Description:
TECHNICAL FIELD
[0001]The present invention provides a novel sodium-dependent bile acid transporter protein, an Na.sup.+/H.sup.+ exchange transporter protein, a P-type ATPase protein, a vanilloid receptor protein, polynucleotides encoding these proteins, antisense polynucleotides to the polynucleotides, antibodies to these proteins, compounds that promote or inhibit the activities of the proteins, a method of screening compounds that promote or inhibit the activities of the proteins, compounds obtained by the screening method, and the like.
BACKGROUND ART
[0002]Bile acid is synthesized in the liver and secreted into a small intestine, and plays an important role in promoting absorption of lipids, lipid-soluble vitamins and cholesterols in the small intestine. Bile acid is re-absorbed efficiently through the small intestine (ileum), returned via a portal vein to the liver and excreted again into bile (enterohepatic circulation). The cholesterol pool size in the body is subject to feedback regulation not only by cholesterol in a meal but also by bile acid in enterohepatic circulation, and thus hypercholesterolemia therapy is conducted by suppression of re-absorption of bile acid into intestines by using a bile acid adsorbent (anion exchange resin).
[0003]The sodium-dependent bile acid transporter is considered to contribute to transport of bile acid. In humans, two isoforms of sodium-dependent bile acid transporter have been identified, and NTCP (Na.sup.+/taurocholate cotransporting polypeptide) is expressed mainly in the liver (J. Clin. Invest., 93, 1326-1331, 1994), while ISBT (ileal sodium/bile salt cotransporter) is expressed mainly in the ileum/kidney (J. Biol. Chem., 270, 27228-27234, 1995). With respect to ISBT, direct relationship between a gene mutation accompanied by amino acid substitution and insufficient absorption of bile acid is suggested (J. Clin. Invest., 99, 1880-1887, 1997).
[0004]A Na.sup.+/H.sup.+ exchange transporter (NHE) is a typical cation antiporter, which couples in animal cells with Na.sup.+ inflow to discharge H.sup.+. NHE is divided into 2 major regions, that is, an amino terminal (N) region containing about 500 amino acids comprising a 10- to 13-times transmembrane region and a carboxyl terminal (C) region comprising about 300 amino acids, and its whole structure is common among isoforms. It is known that the former is an ion transport region comprising an amyloride-binding site, and the latter functions as an activity regulatory region.
[0005]As isoforms of NHE in humans, 6 kinds of isoforms i.e. NHE1 to NHE3 and NHE5 to NHE7 are reported. NHE1 is distributed broadly in tissues, and involved in regulation of intracellular pH and cell volume. The activity of NHE1 is promoted by a growth factor or simulation with high osmotic pressure, resulting in an increase in intracellular pH. NHE3 is expressed in the kidney and small intestine, and plays an important role in absorption of Na.sup.+. It is thus known that the respective isoforms are different in their expression distribution, regulatory mechanism, and the effect of inhibitor.
[0006]NHE1 is considered as one factor increasing intracellular Na.sup.+ levels after ischemia and participating in causing myocardial difficulties. It is also reported that the activity of NHE1 in patients with hypertension is significantly higher than in healthy persons. In mice spontaneously developing epilepsy, it is confirmed that the disease is caused by a mutation in NHE (Cell, 91, 139-148, 1997).
[0007]P-type ATPase is a membrane enzyme participating in transport of various substrates by utilizing energy upon hydrolysis of ATP. The P-type ATPase is divided into 3 classes, depending on its substrate. Type-1 utilizes heavy metals such as Cu2+ ion and Cd2+ ion as the substrate, possesses an N-terminal characteristic structure involved in binding to heavy metals, and has an 8-times transmembrane structure. Wilson's disease is a disease accompanying an abnormality in Cu2+-ATPase participating in excretion of copper in the liver. Type-2 utilizes alkali metals (K.sup.+ ion, Na.sup.+ ion), alkaline earth metals (Ca2+ ion) or proton (H.sup.+) as the substrate. In particular, H.sup.+, K.sup.+-ATPase (proton pump) in stomach acid-secreting cells is a target of chemicals such as proton pump inhibitors (omeplazole, lansoprazole etc.) that are therapeutic products for stomach ulcer/duodenum ulcer/reflux esophagitis. Further, Na.sup.+, K.sup.+-ATPase (sodium pump) is a target of chemicals such as cardiac glycosides used for cardiac diseases, and its activity is inhibited by ouabain. Type-3 is the latest determined type, and utilizes aminophospholipids as the substrate. It is also called aminophospholipid translocase (flippase), and reversely transfer phospholipids selectively from outer to inner layers by using energy generated upon hydrolysis of ATP. It is estimated that uneven distribution of lipids on the biomembrane is thereby maintained. No significant difference in structure is recognized between type-2 and type-3, both of which have a 10-times transmembrane structure (Biochemistry, 34, 15607-15613, 1995; Science, 272, 1495-1497, 1996).
[0008]Up to now, 17 isoforms of P-type ATPase of type-3 have been identified in mammals. Among them, FIC1 is expressed in tissues such as the pancreas, small intestine, liver etc., and the relationship between an alteration in its gene and hereditary cholestasis is reported (Nature Genet., 18, 219-224, 1998).
[0009]The P-type ATPase of type 3 is considered to play an important role in transport of aminophospholipids and in uneven distribution of lipids on the biomembrane, but the detailed functions and structure of each isoform and the relationship thereof with the disease are not so revealed.
[0010]As a pain receptor, a vanilloid receptor subtype 1 (VR1) is a non-selective cation channel with high Ca2+ permeability having outward rectification. It is known that VR1 has a 6-times transmembrane region, possesses an H5 region regarded as forming a pore between fifth and sixth transmembrane sites, and has 3 ankyrin repeat domains at the N-terminal thereof. In addition to VR1 (Biochemical and Biophysical Research Communications, 281, 1183, 2001), VRL (vanilloid receptor-like protein) 1 and VRL2 in humans have been cloned up to now, and have about 40% homology with VR1 respectively (Physiol Genomics 4, 165-174, 2001).
[0011]Capsaicin has a vanillyl group and is thus called vanilloid, and is an extraneous ligand of vanilloid receptor. No intrinsic ligand has been revealed. Single electric current measurement revealed that VR1 is activated electrophysiologically directly by capsaicin. Further, VR1 is a receptor of multi-stimuli, which is activated not only by chemical stimulation with capsaicin or the like but also by heat stimulation regarded pain stimulation (at a temperature of higher than 43° C. that is a threshold temperature at which pain is induced in humans) and acid stimulation (tissues are acidified in inflammations and ischemia).
[0012]VR1 is activated by stimuli (for example capsaicin, heat, proton) causing pain in the living body, and in a morbid state, these stimuli are considered to occur not singly but simultaneously. Receptiveness of every pain in the living body is not elucidated by only VR1, and the presence of other homologues and cofactors is also estimated. In the previously reported VR family, there are various expression sites and stimulation receptivity, and these are considered to function depending on one another, to transmit pain stimulation.
[0013]The sodium-dependent bile acid transporter is considered to play an important role in transport of bile acid in the liver and small intestine, but its detailed mechanism and the relationship thereof with the disease are not so revealed. Full elucidation of the substrate specificity of the sodium-dependent bile acid transporter and its role in bile acid metabolism leads to development of therapeutic products for diseases associated with bile acid metabolism.
[0014]As described above, NHE is involved in many morbid states, and elucidation of the mechanism of activation and regulation of each isoform of NHE leads to development of therapeutic products.
[0015]Elucidation of detailed functions of P-type ATPase of type 3 leads to development of therapeutic products for diseases such as metabolic diseases, central nerve diseases, genital diseases and cancers associated with P-type ATPase of type 3.
[0016]The above-mentioned capsaicin is used as an analgesic for relieving pains in diabetic neurosis and articular rheumatism, and thus elucidation of the structure, function and mutual relationship of VR family is considered to lead to development of therapeutic products for pains as a whole.

[0100]As salts of the protein or partial peptide of the present invention, use is made of salts with physiologically acceptable acids (e.g., inorganic acids or organic acids) or bases (e.g., alkali metal salts), preferably physiologically acceptable acid addition salts. Examples of such salts are salts with inorganic acids (e.g., hydrochloric acid, phosphoric acid, hydrobromic acid, sulfuric acid), salts with organic acids (e.g., acetic acid, formic acid, propionic acid, fumaric acid, maleic acid, succinic acid, tartaric acid, citric acid, malic acid, oxalic acid, benzoic acid, methanesulfonic acid, benzenesulfonic acid) and the like.
[0101]The protein or partial peptide of the present invention or salts thereof may be manufactured from the human and other warm-blooded animal cells or tissues described above by a publicly known protein purification method, or by culturing a transformant that comprises the DNA encoding the protein of the present invention. Furthermore, the protein or partial peptide or salts thereof may also be manufactured by the peptide synthesis method, which will be described below.
[0102]Where the protein or its salts are manufactured from human and other mammalian tissues or cells, human or other mammalian tissues or cells are homogenized, then extracted with an acid or the like, and the extract is isolated and purified by a combination of chromatography techniques such as reverse phase chromatography, ion exchange chromatography, and the like.
[0103]To synthesize the protein of the present invention, its partial peptide, or salts or amides thereof according to the present invention, commercially available resins that are used for protein synthesis may be used. Examples of such resins include chloromethyl resin, hydroxymethyl resin, benzhydrylamine resin, aminomethyl resin, 4-benzyloxybenzyl alcohol resin, 4-methylbenzhydrylamine resin, PAM resin, 4-hydroxymethylmethylphenyl acetamidomethyl resin, polyacrylamide resin, 4-(2',4'-dimethoxyphenylhydroxymethyl)phenoxy resin, 4-(2',4'-dimethoxyphenyl-Fmoc-aminoethyl) phenoxy resin, etc. Using these resins, amino acids in which α-amino groups and functional groups on the side chains are appropriately protected are condensed on the resin in the order of the sequence of the objective protein according to various condensation methods publicly known in the art. At the end of the reaction, the protein is excised from the resin and at the same time, the protecting groups are removed. Then, intramolecular disulfide bond-forming reaction is performed in a highly diluted solution to obtain the objective protein or the partial peptide, or amides thereof.
[0104]For condensation of the protected amino acids described above, a variety of activation reagents for protein synthesis may be used, and carbodiimides are particularly preferable. Examples of such carbodiimides include DCC, N,N'-diisopropylcarbodiimide, N-ethyl-N'-(3-dimethylaminopropyl)carbodiimide, etc. For activation by these reagents, the protected amino acids in combination with a racemization inhibitor (e.g., HOBt, HOOBt) are added directly to the resin, or the protected amino acids are previously activated in the form of symmetric acid anhydrides, HOBt esters or HOOBt esters, followed by adding the thus activated protected amino acids to the resin.
[0105]Solvents suitable for use to activate the protected amino acids or condense with the resin may be appropriately chosen from solvents known to be usable for protein condensation reactions. Examples of such solvents are acid amides such as N,N-dimethylformamide, N,N-dimethylacetamide, N-methylpyrrolidone, etc.; halogenated hydrocarbons such as methylene chloride, chloroform, etc.; alcohols such as trifluoroethanol, etc.; sulfoxides such as dimethylsulfoxide, etc.; ethers such as pyridine, dioxane, tetrahydrofuran, etc.; nitriles such as acetonitrile, propionitrile, etc.; esters such as methyl acetate, ethyl acetate, etc.; and appropriate mixtures of these solvents. The reaction temperature is appropriately chosen from the range known to be applicable to protein binding reactions and is usually selected in the range of approximately -20° C. to 50° C. The activated amino acid derivatives are used generally in an excess of 1.5 to 4 times. The condensation is examined by a test using the ninhydrin reaction; when the condensation is insufficient, the condensation can be completed by repeating the condensation reaction without removal of the protecting groups. When the condensation is yet insufficient even after repeating the reaction, unreacted amino acids are acetylated with acetic anhydride or acetylimidazole to cancel any possible adverse effect on the subsequent reaction.
[0106]Examples of the protecting groups used to protect the amino groups of the starting materials include Z, Boc, t-pentyloxycarbonyl, isobornyloxycarbonyl, 4-methoxybenzyloxycarbonyl, Cl--Z, Br--Z, adamantyloxycarbonyl, trifluoroacetyl, phthaloyl, formyl, 2-nitrophenylsulphenyl, diphenylphosphinothioyl, Fmoc, etc.
[0107]A carboxyl group can be protected by, e.g., alkyl esterification (in the form of linear, branched or cyclic alkyl esters of the alkyl moiety such as methyl, ethyl, propyl, butyl, t-butyl, cyclopentyl, cyclohexyl, cycloheptyl, cyclooctyl, 2-adamantyl, etc.), aralkyl esterification (e.g., esterification in the form of benzyl ester, 4-nitrobenzyl ester, 4-methoxybenzyl ester, 4-chlorobenzyl ester, benzhydryl ester, etc.), phenacyl esterification, benzyloxycarbonyl hydrazidation, t-butoxycarbonyl hydrazidation, trityl hydrazidation, or the like.
[0108]The hydroxyl group of serine can be protected through, for example, its esterification or etherification. Examples of groups appropriately used for the esterification include a lower (C1-6) alkanoyl group, such as acetyl group, an aroyl group such as benzoyl group, and a group derived from carbonic acid such as benzyloxycarbonyl group, ethoxycarbonyl group, etc. Examples of a group appropriately used for the etherification include benzyl group, tetrahydropyranyl group, t-butyl group, etc.
[0109]Examples of groups for protecting the phenolic hydroxyl group of tyrosine include Bzl, Cl2-Bzl, 2-nitrobenzyl, Br--Z, t-butyl, etc.
[0110]Examples of groups used to protect the imidazole moiety of histidine include Tos, 4-methoxy-2,3,6-trimethylbenzenesulfonyl, DNP, benzyloxymethyl, Bum, Boc, Trt, Fmoc, etc.
[0111]Examples of the activated carboxyl groups in the starting materials include the corresponding acid anhydrides, azides, activated esters (esters with alcohols (e.g., pentachlorophenol, 2,4,5-trichlorophenol, 2,4-dinitrophenol, cyanomethyl alcohol, p-nitrophenol, HONB, N-hydroxysuccimide, N-hydroxyphthalimide, HOBt)). As the activated amino acids in which the amino groups are activated in the starting material, the corresponding phosphoric amides are employed.
[0112]To eliminate (split off) the protecting groups, there are used catalytic reduction under hydrogen gas flow in the presence of a catalyst such as Pd-black or Pd-carbon; an acid treatment with anhydrous hydrogen fluoride, methanesulfonic acid, trifluoromethane-sulfonic acid or trifluoroacetic acid, or a mixture solution of these acids; a treatment with a base such as diisopropylethylamine, triethylamine, piperidine or piperazine; and reduction with sodium in liquid ammonia. The elimination of the protecting group by the acid treatment described above is carried out generally at a temperature of approximately -20° C. to 40° C. In the acid treatment, it is efficient to add a cation scavenger such as anisole, phenol, thioanisole, m-cresol, p-cresol, dimethylsulfide, 1,4-butanedithiol or 1,2-ethanedithiol, which is activated by ligand. Furthermore, 2,4-dinitrophenyl group known as the protecting group for the imidazole of histidine is removed by a treatment with thiophenol. Formyl group used as the protecting group of the indole of tryptophan is eliminated by the aforesaid acid treatment in the presence of 1,2-ethanedithiol or 1,4-butanedithiol, as well as by a treatment with an alkali such as a dilute sodium hydroxide solution and dilute ammonia.
[0113]Protection of functional groups that should not be involved in the reaction of the starting materials, protecting groups, elimination of the protecting groups and activation of functional groups involved in the reaction may be appropriately selected from publicly known groups and publicly known means.
[0114]In another method for obtaining the amides of the protein or partial peptide, for example, the α-carboxyl group of the carboxy terminal amino acid is first protected by amidation, and the peptide (protein) chain is then extended from the amino group side to a desired length. Thereafter, a protein or partial peptide in which only the protecting group of the N-terminal α-amino group in the peptide chain has been eliminated from the protein and a protein or partial peptide in which only the protecting group of the C-terminal carboxyl group has been eliminated are prepared. The two proteins or peptides are condensed in a mixture of the solvents described above. The details of the condensation reaction are the same as described above. After the protected protein or peptide obtained by the condensation is purified, all the protecting groups are eliminated by the method described above to give the desired crude protein or peptide. This crude protein or peptide is purified by various known purification means. Lyophilization of the major fraction gives the amide of the desired protein or peptide.
[0115]To prepare the esterified protein or peptide, for example, the α-carboxyl group of the carboxy terminal amino acid is condensed with a desired alcohol to prepare the amino acid ester, which is followed by procedure similar to the preparation of the amidated protein or peptide above to give the ester form of the desired protein or peptide.
[0116]The partial peptide of the present invention or its salts can be manufactured by publicly known methods for peptide synthesis, or by cleaving the protein of the present invention with an appropriate peptidase. For the methods for peptide synthesis, for example, either solid phase synthesis or liquid phase synthesis may be used. That is, the partial peptide or amino acids that can construct the partial peptide of the present invention are condensed with the remaining part. Where the product contains protecting groups, these protecting groups are removed to give the desired peptide. Publicly known methods for condensation and elimination of the protecting groups are described in (a) to (e) below.

[0158]Thus, the transformant transformed with the expression vector comprising the DNA encoding the protein can be obtained.
[0159]Where the host is bacteria belonging to the genus Escherichia or the genus Bacillus, the transformant can be appropriately incubated in a liquid medium which contains materials required for growth of the transformant such as carbon sources, nitrogen sources, inorganic materials, and so on.

[0160]A preferred example of the medium for incubation of the bacteria belonging to the genus Escherichia is M9 medium supplemented with glucose and Casamino acids (Miller, Journal of Experiments in Molecular Genetics, 431-433, Cold Spring Harbor Laboratory, New York, 1972). If necessary and desired, a chemical such as 3β-indolylacrylic acid can be added to the medium to activate the promoter efficiently.
[0161]Where the bacteria belonging to the genus Escherichia are used as the host, the transformant is usually cultivated at about 15° C. to about 43° C. for about 3 hours to about 24 hours. If necessary and desired, the culture may be aerated or agitated.
[0162]Where the bacteria belonging to the genus Bacillus are used as the host, the transformant is cultivated generally at about 30° C. to about 40° C. for about 6 hours to about 24 hours. If necessary and desired, the culture can be aerated or agitated.

[0166]As described above, the protein of the present invention can be produced in the cell, in the cell membrane or out of the cell of the transformant.
[0167]The protein of the present invention can be separated and purified from the culture described above by the following procedures.
[0168]When the protein of the present invention is extracted from the culture or cells after cultivation, the transformants or cells are collected by a publicly known method and suspended in an appropriate buffer. The transformants or cells are then disrupted by publicly known methods such as ultrasonication, a treatment with lysozyme and/or freeze-thaw cycling, followed by centrifugation, filtration, etc. Thus, the crude extract of the protein of the present invention can be obtained. The buffer used for the procedures may contain a protein modifier such as urea or guanidine hydrochloride, or a surfactant such as TRITON X-100® (Polyoxyethylene (10) Octylphenyl Ether), etc. When the protein is secreted in the culture, the supernatant after completion of the cultivation can be separated from the transformants or cells to collect the supernatant by a publicly known method.
[0169]The protein contained in the supernatant or the extract thus obtained can be purified by appropriately combining the publicly known methods for separation and purification. Such publicly known methods for separation and purification include a method utilizing difference in solubility such as salting out, solvent precipitation, etc.; a method utilizing mainly difference in molecular weight such as dialysis, ultrafiltration, gel filtration, SDS-polyacrylamide gel electrophoresis, etc.; a method utilizing difference in electric charge such as ion exchange chromatography, etc.; a method utilizing difference in specific affinity such as affinity chromatography, etc.; a method utilizing difference in hydrophobicity such as reverse phase high performance liquid chromatography, etc.; a method utilizing difference in isoelectric point such as isoelectrofocusing electrophoresis; and the like.

[Preparation of Monoclonal Antibody]
(a) Preparation of Monoclonal Antibody-Producing Cells
[0175]The protein of the present invention is administered to mammals either solely or together with carriers or diluents to the site where the production of antibody is possible by the administration. In order to potentiate the antibody productivity upon the administration, complete Freund's adjuvants or incomplete Freund's adjuvants may be administered. The administration is usually carried out once in every two to six weeks and 2 to 10 times in total. Examples of the applicable warm-blooded animals are monkeys, rabbits, dogs, guinea pigs, mice, rats, sheep, goats and chickens, with mice and rats being preferred.
[0176]In the preparation of monoclonal antibody-producing cells, warm-blooded animals, e.g., mice, immunized with an antigen wherein the antibody titer is noted is selected, then the spleen or lymph node is collected after 2 to 5 days from the final immunization and antibody-producing cells contained therein are fused with myeloma cells from an animal of the same or different species to give monoclonal antibody-producing hybridomas. Measurement of the antibody titer in antisera may be made, for example, by reacting a labeled form of the protein, which will be described later, with the antiserum followed by assaying the binding activity of the labeling agent bound to the antibody. The fusion may be operated, for example, by the known Koehler and Milstein method (Nature, 256, 495, 1975). Examples of the fusion accelerator are polyethylene glycol (PEG), Sendai virus, etc., among which PEG is preferably employed.
[0177]Examples of the myeloma cells are warm-blooded animal myeloma cells such as NS-1, P3U1, SP2/0, AP-1 etc., among which P3U1 is particularly preferably employed. A preferred ratio of the count of the antibody-producing cells used (spleen cells) to the count of myeloma cells is within a range of approximately 1:1 to 20:1. When PEG (preferably, PEG 1000 to PEG 6000) is added in a concentration of approximately 10 to 80% followed by incubation at about 20 to about 40° C., preferably at about 30 to about 37° C. for about 1 to about 10 minutes, an efficient cell fusion can be carried out.
[0178]Various methods can be used for screening of a monoclonal antibody-producing hybridoma. Examples of such methods include a method which comprises adding the supernatant of hybridoma to a solid phase (e.g., microplate) adsorbed with the protein etc. as an antigen directly or together with a carrier, adding an anti-immunoglobulin antibody (when mouse cells are used for the cell fusion, anti-mouse immunoglobulin antibody is used) labeled with a radioactive substance or an enzyme, or Protein A and detecting the monoclonal antibody bound to the solid phase, and a method which comprises adding the supernatant of hybridoma to a solid phase adsorbed with an anti-immunoglobulin antibody or Protein A, adding the protein labeled with a radioactive substance or an enzyme and detecting the monoclonal antibody bound to the solid phase.
[0179]The monoclonal antibody can be selected by publicly known methods or by modifications of these methods. In general, the selection can be effected in a medium for animal cells supplemented with HAT (hypoxanthine, aminopterin and thymidine). Any selection and growth medium can be employed as far as the hybridoma can grow therein. For example, RPMI 1640 medium containing 1% to 20%, preferably 10% to 20% fetal bovine serum, GIT medium (Wako Pure Chemical Industries, Ltd.) containing 1% to 10% fetal bovine serum, a serum free medium for cultivation of a hybridoma (SFM-101, Nissui Seiyaku Co., Ltd.) and the like can be used for the selection and growth medium. The cultivation is carried out generally at 20° C. to 40° C., preferably at about 37° C., for 5 days to 3 weeks, preferably 1 to 2 weeks. The cultivation can be conducted normally in 5% CO2. The antibody titer of the culture supernatant of hybridomas can be determined as in the assay for the antibody titer in antisera described above.
(b) Purification of Monoclonal Antibody
[0180]Separation and purification of a monoclonal antibody can be carried out by methods applied to conventional separation and purification of immunoglobulins, as in the conventional methods for separation and purification of polyclonal antibodies [e.g., salting-out, alcohol precipitation, isoelectric point precipitation, electrophoresis, adsorption and desorption with ion exchangers (e.g., DEAE), ultracentrifugation, gel filtration, or a specific purification method which comprises collecting only an antibody with an activated adsorbent such as an antigen-binding solid phase, Protein A, Protein G, etc. and dissociating the binding to obtain the antibody].
[Preparation of Polyclonal Antibody]
[0181]The polyclonal antibody of the present invention can be manufactured by publicly known methods or modifications thereof. For example, an immunogen (antigen such as the protein) itself or a complex prepared from an immunogen and a carrier protein is used to immunize a warm-blooded animal a manner similar to the method described above for the manufacture of monoclonal antibodies. The product containing the antibody to the protein of the present invention is collected from the immunized animal followed by separation and purification of the antibody.
[0182]In the complex of an immunogen and a carrier protein used to immunize a warm-blooded animal, the type of carrier protein and the mixing ratio of a carrier to hapten may be any type and in any ratio, as long as the antibody is efficiently produced to the hapten immunized by crosslinking to the carrier. For example, bovine serum albumin, bovine thyroglobulins, hemocyanin, etc. is coupled to hapten in a carrier-to-hapten weight ratio of approximately 0.1 to 20, preferably about 1 to about 5.
[0183]A variety of condensing agents can be used for the coupling of a carrier to hapten. Glutaraldehyde, carbodiimide, maleimide-activated ester, activated ester reagents containing thiol group or dithiopyridyl group, etc. are used for the coupling.
[0184]The condensation product is administered to warm-blooded animals either solely or together with carriers or diluents to the site in which the antibody can be produce by the administration. In order to potentiate the antibody productivity upon the administration, complete Freund's adjuvant or incomplete Freund's adjuvant may be administered. The administration is usually made once approximately in every 2 to 6 weeks and about 3 to about 10 times in total.
[0185]The polyclonal antibody can be collected from the blood, ascites, etc., preferably from the blood of warm-blooded animals immunized by the method described above.
[0186]The polyclonal antibody titer in antiserum can be assayed by the same procedure as that for the determination of serum antibody titer described above. The separation and purification of the polyclonal antibody can be carried out, following the method for the separation and purification of immunoglobulins performed as applied to the separation and purification of monoclonal antibodies described hereinabove.
[0187]The antisense polynucleotide having a complementary or substantially complementary base sequence, or a part of thereof, to the DNA encoding the protein or partial peptide of the present invention (which in the following description of the antisense polynucleotide, is referred to sometimes as the DNA of the present invention) can be any antisense polynucleotide so long as it possesses a complementary or substantially complementary base sequence, or a part thereof, to that of the DNA of the present invention and capable of suppressing expression of the DNA. The antisense polynucleotide is preferably antisense DNA.
[0188]The base sequence substantially complementary to the DNA of the present invention includes, for example, a base sequence having at least about 70% homology, preferably at least about 80% homology, more preferably at least about 90% homology and most preferably at least about 95% homology, to the full-length base sequence or partial base sequence of the base sequence complementary to the DNA of the present invention (i.e., complementary strand to the DNA of the present invention). The base sequence substantially complementary to the DNA of the present invention is particularly an antisense polynucleotide having at least about 70% homology, preferably at least about 80% homology, more preferably at least about 90% homology and most preferably at least about 95% homology to the complementary strand of the base sequence encoding the N-terminal site of the protein of the present invention (e.g., the base sequence around the initiation codon), in the entire base sequence of the complementary strand to the DNA of the present invention.
[0189]Specifically, the base sequence substantially complementary to the DNA of the present invention is an antisense polynucleotide having a complementary or substantially complementary base sequence, or a part thereof, to the base sequence of DNA having the base sequence represented by SEQ ID NO: 2, SEQ ID NO: 11, SEQ ID NO: 12, SEQ ID NO: 13, SEQ ID NO: 19, SEQ ID NO: 41, SEQ ID NO: 43, SEQ ID NO: 60, SEQ ID NO: 61, SEQ ID NO: 62, SEQ ID NO: 67, SEQ ID NO: 103, SEQ ID NO: 105 or SEQ ID NO: 112, preferably an antisense polynucleotide having a complementary or substantially complementary base sequence, or a part thereof, to the base sequence of DNA having the base sequence represented by SEQ ID NO: 2, SEQ ID NO: 11, SEQ ID NO: 12, SEQ ID NO: 13, SEQ ID NO: 19, SEQ ID NO: 41, SEQ ID NO: 43, SEQ ID NO: 60, SEQ ID NO: 61, SEQ ID NO: 62, SEQ ID NO: 67, SEQ ID NO: 103, SEQ ID NO: 105 or SEQ ID NO: 112.
[0190]The antisense polynucleotide is composed of usually about 10 to 40 bases, preferably about 15 to 30 bases.
[0191]For preventing degradation by hydrolases such as nuclease etc., phosphoric acid residues (phosphates) of nucleotides constituting the antisense DNA may be substituted by chemically modified phosphoric acid residues such as phosphorothioate, methylphosphonate, phosphorodithionate etc. These antisense polynucleotides can be manufactured by a publicly known DNA synthesizer and the like.
[0192]According to the present invention, antisense polynucleotides (nucleic acids) which can inhibit the replication or expression of the gene for the protein of the present invention and which correspond to the gene can be designed and synthesized based on the base sequence information of the cloned or determined DNA encoding the protein. Such antisense polynucleotide is capable of hybridizing with RNA of the protein gene of the present invention to inhibit the synthesis or function of said RNA or capable of modulating or controlling the expression of the protein gene of the invention via interaction with the protein-associated RNA of the invention. Polynucleotides complementary to the selected sequences of the protein-RNA of the invention, and polynucleotides specifically hybridizable with the protein-associated RNA of the invention, are useful in modulating or controlling the expression of the protein gene of the invention in vivo and in vitro, and useful for the treatment or diagnosis of diseases. The term "corresponding" is used to mean homologous to or complementary to a particular sequence of the nucleotide, base sequence or nucleic acid including the gene. The term "corresponding" between nucleotides, base sequences or nucleic acids and proteins usually refer to amino acids of a protein under the order derived from the sequence of nucleotides (nucleic acids) or their complements. In the protein genes, the 5' end hairpin loop, 5' end 6-base-pair repeats, 5' end untranslated region, polypeptide translation initiation codon, protein coding region, ORF translation termination codon, 3' end untranslated region, 3' end palindrome region, and 3' end hairpin loop, may be selected as preferred target regions, though any other region may be selected as a target in the protein genes.
[0193]The relationship between the targeted nucleic acids and the polynucleotides complementary to at least a part of the target, or the relationship between the target and the polynucleotides hybridizable with the target, can be denoted to be "antisense". Examples of the antisense polynucleotides include polydeoxynucleotides containing 2-deoxy-D-ribose, polynucleotides containing D-ribose, any other type of polynucleotides which are N-glycosides of a purine or pyrimidine base, or other polymers containing non-nucleotide backbones (e.g., protein nucleic acids and synthetic sequence-specific nucleic acid polymers commercially available) or other polymers containing nonstandard linkages (provided that the polymers contain nucleotides having such a configuration that allows base pairing or base stacking, as is found in DNA or RNA), etc. The antisense polynucleotides may be double-stranded DNA, single-stranded DNA, double-stranded RNA, single-stranded RNA or a DNA:RNA hybrid, and may further include unmodified polynucleotides (or unmodified oligonucleotides), those with publicly known types of modifications, for example, those with labels known in the art, those with caps, methylated polynucleotides, those with substitution of one or more naturally occurring nucleotides by their analogue, those with intramolecular modifications of nucleotides such as those with uncharged linkages (e.g., methyl phosphonates, phosphotriesters, phosphoramidates, carbamates, etc.) and those with charged linkages or sulfur-containing linkages (e.g., phosphorothioates, phosphorodithioates, etc.), those having side chain groups such as proteins (nucleases, nuclease inhibitors, toxins, antibodies, signal peptides, poly-L-lysine, etc.), saccharides (e.g., monosaccharides, etc.), those with intercalators (e.g., acridine, psoralen, etc.), those containing chelators (e.g., metals, radioactive metals, boron, oxidative metals, etc.), those containing alkylating agents, those with modified linkages (e.g., α anomeric nucleic acids, etc.), and the like. Herein the terms "nucleoside", "nucleotide" and "nucleic acid" are used to refer to moieties that contain not only the purine and pyrimidine bases, but also other heterocyclic bases, which have been modified. Such modifications may include methylated purines and pyrimidines, acylated purines and pyrimidines and other heterocyclic rings. Modified nucleotides and modified nucleotides also include modifications on the sugar moiety, wherein, for example, one or more hydroxyl groups may optionally be substituted with a halogen atom(s), an aliphatic group(s), etc., or may be converted into the corresponding functional groups such as ethers, amines, or the like.

Specific examples of the modified nucleic acid include, but are not limited to, sulfur and thiophosphate derivatives of nucleic acids and those resistant to degradation of polynucleoside amides or oligonucleoside amides. The antisense polynucleotides of the present invention can be modified preferably based on the following design, that is, by increasing the intracellular stability of the antisense polynucleotide, increasing the cellular permeability of the antisense polynucleotide, increasing the affinity of the polynucleotide to the targeted sense strand to a higher level, or minimizing the toxicity, if any, of the antisense polynucleotide. Many of such modifications are reported for example in Pharm. Tech. Japan, Vol. 8, p. 247 or 395, 1992, Antisense Research and Applications, CRC Press, 1993, etc.
[0195]The antisense polynucleotide of the present invention may contain altered or modified sugars, bases or linkages. The antisense polynucleotide may also be provided in a specialized form such as liposomes, microspheres, or may be applied to gene therapy, or may be provided in combination with attached moieties. Such attached moieties include polycations such as polylysine that act as charge neutralizers of the phosphate backbone, or hydrophobic moieties such as lipids (e.g., phospholipids, cholesterols, etc.) that enhance the interaction with cell membranes or increase uptake of the nucleic acid. Preferred examples of the lipids to be attached are cholesterols or derivatives thereof (e.g., cholesteryl chloroformate, cholic acid, etc.). These moieties may be attached to the nucleic acid at the 3' or 5' ends thereof and may also be attached thereto through a base, sugar, or intramolecular nucleoside linkage. Other moieties may be capping groups specifically placed at the 3' or 5' ends of the nucleic acid to prevent degradation by nucleases such as exonuclease, RNase, etc. Such capping groups include, but are not limited to, hydroxyl protecting groups known in the art, including glycols such as polyethylene glycol, tetraethylene glycol and the like.

[2] Screening of a Candidate Drug for Diseases
[0235]The protein of the present invention is useful as a reagent for screening a compound or its salt that promotes or inhibits the activity of the protein of the present invention.
[0236]The present invention provides (1) a method of screening a compound or a salt thereof (also referred to hereinafter as a promoter and inhibitor) that promotes or inhibits the activity (e.g., an activity of transporting substrate A etc.) of the protein A of the invention, which comprises using the protein A of the present invention. More specifically, the present invention provides, for example,
(2) a method of screening a promoter or an inhibitor, which comprises comparing (i) the substrate A transport activity of a cell having an ability to produce the protein A of the present invention with (ii) the substrate A transport activity of a mixture of a test compound and a cell having an ability to produce the protein A of the present invention.
[0237]Specifically, the amount of the substrate A in a labeled form incorporated into the cell is measured and compared between (i) and (ii) in the screening method described above.
[0238]As the labeling agent, use is made of, for example, radioisotopes (for example, [3H], [125I], [14C], [32P], [33P], [35S], etc.), fluorescent substances (for example, cyanine fluorescent dyes (e.g., Cy2, Cy3, Cy5, Cy5.5, Cy7 (Amersham Bioscience) etc), fluorescein etc.), luminescent substances (for example, luminol etc.), enzymes (for example, peroxidase etc.) or lanthanide elements.
[0239]As the labeled substrate A, use is made of, for example, [6,7-3H(N)]-estrone sulfate or [1,2,6,7-3H(N)]-dehydroepiandrosterone sulfate.
[0240]Examples of the test compounds include peptides, proteins, non-peptide compounds, synthetic compounds, fermentation products, cell extracts, plant extracts, animal tissue extracts, etc. and these compounds may be novel compounds or publicly known compounds.
[0241]To perform the screening method described above, a protein preparation is prepared by suspending cells having an ability to produce the protein A of the present invention, in a buffer appropriate for screening. A buffer such as a phosphate buffer or a borate buffer having a pH value of about 4 to 10 (preferably pH of about 6 to 8) can be used so long as it does not inhibit the activity of the protein A of the present invention.
[0242]As the cells having an ability to produce the protein A of the present invention, for example a host (transformant) transformed with a vector comprising the DNA encoding the protein A of the present invention described above is used. As the host, animal cells such as CHO cells are preferably used. In the screening, for example a transformant expressing the protein A of the present invention on a cell membrane by culturing it by the method described above is preferably used.
[0243]The substrate A transport activity can be measured according to known methods, for example a method described in Am. J. Physiol., 274, G157-169, 1998 or a modification thereto.
[0244]For example, a compound or a salt thereof that promotes the substrate A transport activity in (ii) above by about at least 20%, preferably at least 30%, more preferably about at least 50% as compared with the activity in (i) above can be selected as a compound or a salt thereof that promotes the activity of the protein A of the present invention.
[0245]For example, a compound or a salt thereof that inhibits the substrate A transport activity in (ii) above by about at least 20%, preferably at least 30%, more preferably about at least 50% as compared with the activity in (i) above can be selected as a compound or a salt thereof that inhibits (or suppresses) the activity of the protein A of the present invention.

As the host, animal cells such as CHO cells are preferably used. In the screening, for example a transformant expressing the protein of the present invention on a cell membrane by culturing it by the method described above is preferably used.
[0272]The cation channel activity of the protein D of the present invention can be measured according to known methods, for example a method described in Nature, 389, 816, 1997 or a modification thereto.
[0273]For example, a test compound that promotes the cation channel activity in (ii''') above by about at least 20%, preferably at least 30%, more preferably about at least 50% as compared with the activity in (i''') above can be selected as a compound or a salt thereof that promotes the activity of the protein D of the present invention.

[0275]Alternatively, after a gene for secretory alkaline phosphatase, luciferase or the like is inserted into a region downstream from a promoter of the protein D gene of the present invention and the gene is expressed in the cells described above, a compound or a salt thereof that promotes or inhibits the expression of the protein D of the present invention (that is, a compound or a salt thereof that promotes or inhibits the activity of the protein D of the present invention) can be screened by examining whether a test compound when brought into contact with the cells activates or inhibits the enzyme activity.
[0276]Using the protein D of the present invention, or using the ligand binding assay system of the expression system constructed using a recombinant of the protein D of the present invention, compounds (e.g., peptides, proteins, non-peptide compounds, synthetic compounds, fermentation products, etc.) or salt forms thereof that alter the binding property between the protein D of the present invention and its ligand (hereinafter referred to as the ligand of the present invention) can be efficiently screened.
[0277]Specifically, the case (i) where the ligand of the present invention is brought into contact with the protein D of the present invention is compared with the case (ii) where the ligand of the present invention and a test compound are brought into contact with the protein D of the present invention. In this comparison, for example the amount of the ligand of the present invention bound to the protein D of the present invention is measured.
[0278]Specifically, the screening method of the present invention includes, for example:
(a) a method of screening a compound or its salt that alters the binding property between the ligand of the present invention and the protein D of the present invention, which comprises measuring and comparing the amount of the ligand of the invention bound to the protein D of the invention in the case where the ligand of the invention is brought into contact with the protein D of the invention, with that in the case where the ligand of the invention and a test compound are brought into contact with the protein D of the invention,(b) a method of screening a compound or its salt that alters the binding property between the ligand of the present invention and the protein D of the present invention, which comprises measuring and comparing the amount of the ligand of the invention bound to cells containing the protein D of the invention or a membrane fraction of the cells in the case where the ligand of the invention is brought into contact with the cells or the cell membrane fraction, with that in the case where the ligand of the invention and a test compound are brought into contact with the cells or the cell membrane fraction,(c) the screening method according to the above-mentioned (b), wherein the protein D of the present invention is the protein D of the present invention which was expressed on a cell membrane by culturing a transformant comprising DNA encoding the protein D of the present invention, and(d) the screening method according to the above-mentioned (a) to (c), wherein the ligand of the present invention is a labeled ligand.
[0279]The protein D of the present invention is preferably the one in membrane fractions from organs in humans or warm-blooded animals. However, acquisition of human-derived organs is extremely difficult, and thus the protein D used in screening is preferably the one expressed in a large amount by a transformant.
[0280]For producing the protein D of the present invention, the above-described process for producing the protein D of the resent invention is used.
[0281]When cells containing the protein D of the present invention or a membrane fraction of the cells is used in the screening method described above, a preparation method described later may be followed.
[0282]Where cells containing the protein D of the present invention are used, the cells may be fixed using glutaraldehyde, formalin, etc. The fixation can be made by a publicly known method.
[0283]The cells containing the protein D of the present invention are host cells that have expressed the protein D of the present invention, and the host cells include Escherichia coli, Bacillus subtilis, yeast, insect cells, animal cells, and the like. The method of producing the cells is the same as described above.
[0284]The cell membrane fraction refers to a fraction abundant in cell membrane obtained by cell disruption and subsequent fractionation by a publicly known method. Useful cell disruption methods include cell squashing using a Potter-Elvehjem homogenizer, disruption using a Waring blender or Polytron (manufactured by Kinematica Inc.), disruption by ultrasonication, and disruption by cell spraying through thin nozzles under an increased pressure using a French press or the like. Cell membrane fractionation is effected mainly by fractionation using a centrifugal force, such as centrifugation for fractionation and density gradient centrifugation. For example, cell disruption fluid is centrifuged at a low speed (500 rpm to 3,000 rpm) for a short period of time (normally about 1 to about 10 minutes), the resulting supernatant is then centrifuged at a higher speed (15,000 rpm to 30,000 rpm) normally for 30 minutes to 2 hours. The precipitate thus obtained is used as the membrane fraction. The membrane fraction is rich in the protein D expressed and membrane components such as cell-derived phospholipids and membrane proteins.
[0285]The amount of the protein D of the invention in the cells containing the protein D and in the membrane fraction of the cells is preferably 103 to 108 molecules per cell, more preferably 105 to 107 molecules per cell. As the amount of expression increases, the ligand binding activity per unit of membrane fraction (specific activity) increases so that not only the highly sensitive screening system can be constructed but also large quantities of samples can be assayed with the same lot.
[0286]To carry out the screening method described above, for example a fraction of the protein D of the present invention and the ligand of the present invention (for example, the labeled ligand of the present invention) are used. The fraction of the protein D of the present invention is preferably a fraction of the naturally occurring protein D of the present invention or the recombinant protein D of the present invention having an activity equivalent to that of the natural protein. Herein, the equivalent activity is intended to mean a ligand binding activity etc. As the labeled ligand, use can be made of ligands labeled for example with radioisotopes (for example, [3H], [125I], [14C], [32P], [33P], [35S], etc.), fluorescent substances (for example, cyanine fluorescent dyes (e.g., Cy2, Cy3, Cy5, Cy5.5, Cy7 (Amersham Bioscience) etc), fluorescein etc.), luminescent substances (for example, luminol etc.), enzymes (for example, peroxidase etc.) or lanthanide elements.
[0287]Specifically, to screen the compounds or salts thereof that alter the binding property between the ligand of the present invention and the protein D of the present invention, first, the receptor standard is prepared by suspending cells or cell membrane fraction containing the protein D of the present invention in a buffer appropriate for the screening. For the buffer, any buffer that does not interfere with the binding of the ligand to the protein is usable and examples of such a buffer are phosphate buffer, Tris-hydrochloride buffer, etc., having a pH value of 4 to 10 (preferably a pH value of 6 to 8). To minimize a non-specific binding, a surfactant such as CHAPS, TWEEN-80® (Polyoxyethylene (20) Sorbitan Monooleate) (Kao-Atlas Co.), digitonin, deoxycholate, etc. may be added to the buffer. To inhibit degradation of the protein D of the present invention by proteases, protease inhibitors such as PMSF, leupeptin, E-64 (manufactured by Peptide Research Laboratory, Co.), and pepstatin may be added. A predetermined amount (5,000 to 500,000 cpm) of the labeled ligand of the present invention is added to 0.01 to 10 ml solution of the protein in the coexistence of 10-10 to 10-7 M test compound. To examine non-specific binding (NSB), a reaction tube containing the unlabeled ligand of the present invention in large excess is also prepared. The reaction is carried out at approximately 0 to 50° C., preferably about 4 to 37° C. for about 20 minutes to about 24 hours, preferably about 30 minutes to about 3 hours. After completion of the reaction, the reaction mixture is filtrated through glass fiber filter paper, etc. and washed with an appropriate volume of the same buffer. The residual radioactivity on the glass fiber filter paper is then measured by means of a liquid scintillation counter or γ-counter. Assuming that the count (B0-NSB) obtained by subtracting the amount of non-specific binding (NSB) from the count obtained in the absence of any competitive substance (B0) is 100%, the test compound by which the amount of specific binding (B-NSB) is reduced for example to 50% or less can be selected as a candidate substance having a potential of competitive inhibition.

[3] Quantification of the Protein of the Present Invention, its Partial Peptide, or its Salt
[0326]The antibody of the present invention is capable of specifically recognizing the protein of the present invention and can thus be used for quantification of the protein of the present invention in a test sample fluid, in particular, for quantification by the sandwich immunoassay.
[0327]That is, the present invention provides:
(i) a method for quantification of the protein of the present invention in a test sample fluid, which comprises competitively reacting the antibody of the present invention, a test sample fluid and a labeled form of the protein of the present invention, and measuring the ratio of the labeled protein of the present invention bound to the antibody; and(ii) a method for quantification of the protein of the present invention in a test sample fluid, which comprises reacting the test sample fluid simultaneously or continuously with the antibody of the present invention immobilized on a carrier and a labeled form of the antibody of the present invention, and then measuring the activity of the labeling agent on the insoluble carrier.
[0328]In the quantification method in the above-mentioned (ii), it is desirable that one antibody is an antibody recognizing the N-terminal region of the protein of the present invention, and the other antibody is an antibody reacting with the C-terminal region of the protein of the present invention.
[0329]The monoclonal antibody to the protein of the present invention (hereinafter sometimes referred to as the monoclonal antibody of the present invention) may be used to quantify the protein of the present invention. Besides, the protein of the present invention may also be detected by means of tissue staining. For these purposes, the antibody molecule per se may be used or F(ab')2, Fab' or Fab fractions of the antibody molecule may be used as well.
[0330]There is no particular limitation to the method of quantifying the protein of the present invention using the antibody of the present invention; any method may be used so far as it relates to a method in which the amount of antibody, antigen or antibody-antigen complex can be detected by a chemical or a physical means, depending on or corresponding to the amount of antigen (e.g., the amount of the protein) in a test sample fluid to be assayed, and then calculated using a standard curve prepared by a standard solution containing the known amount of antigen. Advantageously used are, for example, nephrometry, competitive method, immunometric method and sandwich method; in terms of sensitivity and specificity, the sandwich method, which will be later described, is particularly preferred.
[0331]Examples of the labeling agent used in the assay method using the labeling substance are radioisotopes (for example, [125I], [131I], [3I], [14C] etc.), fluorescent substances [for example, cyanine fluorescent dyes (e.g., Cy2, Cy3, Cy5, Cy5.5, Cy7 (Amersham Bioscience) etc), fluorescamine, fluorescein isothiocyanate etc.], enzymes (for example, β-galactosidase, β-glucosidase, alkaline phosphatase, peroxidase, malate dehydrogenase etc), luminescent substances (for example, luminol, a luminol derivative, luciferin, lucigenin etc.), biotin, and lanthanide elements. Furthermore, the biotin-avidin system may also be used for binding of an antibody or antigen to a labeling agent.
[0332]For immobilization of antigen or antibody, physical adsorption may be used. Chemical binding methods conventionally used for insolubilization or immobilization of proteins or enzymes may also be used. For the carrier, for example, insoluble polysaccharides such as agarose, dextran, cellulose, etc.; synthetic resin such as polystyrene, polyacrylamide, silicon, etc., and glass or the like. are used.
[0333]In the sandwich method, the immobilized monoclonal antibody of the present invention is reacted with a test fluid (primary reaction), then with the labeled monoclonal antibody of the present invention (secondary reaction), and the activity of the label on the immobilizing carrier is measured, whereby the amount of the protein of the present invention in the test fluid can be quantified. The order of the primary and secondary reactions may be reversed, and the reactions may be performed simultaneously or with an interval. The methods of labeling and immobilization can be performed by the methods described above. In the immunoassay by the sandwich method, the antibody used for immobilized or labeled antibodies is not necessarily one species, but a mixture of two or more species of antibody may be used to increase the measurement sensitivity.
[0334]In the method for assaying the protein of the present invention by the sandwich method according to the present invention, preferred monoclonal antibodies of the present invention used for the primary and the secondary reactions are antibodies whose binding sites to the protein of the present invention are different from one another. Thus, the antibodies used in the primary and the secondary reactions are those wherein, when the antibody used in the secondary reaction recognizes the C-terminal region of the protein of the present invention, the antibody recognizing the site other than the C-terminal region, e.g., recognizing the N-terminal region, is preferably used in the primary reaction.
[0335]The monoclonal antibody of the present invention may be used in an assay system other than the sandwich method, such as a competitive method, an immunometric method, nephrometry, etc.
[0336]In the competitive method, an antigen in a test sample fluid and a labeled antigen are competitively reacted with an antibody, then the unreacted labeled antigen (F) and the labeled antigen bound to the antibody (B) are separated (B/F separation) and the labeled amount of either B or F is measured to determine the amount of the antigen in the test sample fluid. In the reactions for such a method, there are a liquid phase method in which a soluble antibody is used as the antibody and the B/F separation is effected by polyethylene glycol while a second antibody to the antibody described above is used, and a solid phase method in which an immobilized antibody is used as the first antibody or a soluble antibody is used as the first antibody while an immobilized antibody is used as the second antibody.
[0337]In the immunometric method, an antigen in a test sample fluid and an immobilized antigen are competitively reacted with a given amount of a labeled antibody followed by separating the solid phase from the liquid phase; or an antigen in a test sample fluid and an excess amount of labeled antibody are reacted, then an immobilized antigen is added to bind an unreacted labeled antibody to the solid phase, and the solid phase is separated from the liquid phase. Thereafter, the labeled amount of any of the phases is measured to determine the antigen amount in the test sample fluid.
[0338]In the nephrometry, the amount of insoluble sediment, which is produced as a result of the antigen-antibody reaction in a gel or in a solution, is measured. Even when the amount of an antigen in a test sample fluid is small and only a small amount of the sediment is obtained, laser nephrometry utilizing laser scattering can be suitably used.
[0339]In applying each of those immunoassays to the quantification method of the present invention, any special conditions or operations are not required to set forth. The assay system for the protein of the present invention may be constructed in addition to conditions or operations conventionally used for each of the methods, taking the technical consideration by one skilled in the art into account. For the details of such conventional technical means, a variety of reviews, reference books, etc. may be referred to (for example, Hiroshi Irie (ed.): "Radioimmunoassay" (published by Kodansha, 1974); Hiroshi Irie (ed.): "Radioimmunoassay; Second Series" (published by Kodansha, 1979); Eiji Ishikawa, et al.

[6] Creation of an Animal Having the DNA of the Present Invention
[0374]The present invention provides a non-human mammal having the DNA encoding the protein of the present invention, which is exogenous (hereinafter simply referred to as the exogenous DNA of the present invention) or its mutant DNA (sometimes simply referred to as the exogenous mutant DNA of the present invention).
[0375]Thus, the present invention provides:
(1) a non-human mammal having the exogenous DNA of the present invention or its mutant DNA;(2) the mammal according to (1), wherein the non-human mammal is a rodent;(3) the mammal according to (2), wherein the rodent is mouse or rat; and(4) a recombinant vector comprising the exogenous DNA of the present invention or its mutant DNA and capable of expression in a mammal.
[0376]The non-human mammal having the exogenous DNA of the present invention or its mutant DNA (hereinafter simply referred to as the DNA transgenic animal of the present invention) can be created by transfecting a desired DNA into an unfertilized egg, a fertilized egg, a spermatozoon, a germinal cell containing a primordial germinal cell thereof, or the like, preferably in the embryogenic stage in the development of a non-human mammal (more preferably in the single cell or fertilized cell stage and generally before the 8-cell phase) by standard means such as the calcium phosphate method, the electric pulse method, the lipofection method, the agglutination method, the microinjection method, the particle gun method, the DEAE-dextran method, etc. Also, it is possible to transfect the exogenous DNA of the present invention into a somatic cell, a living organ, a tissue cell or the like, by the DNA transfection methods, and utilize the transformant for cell culture, tissue culture, etc. In addition, these cells may be fused with the above-described germinal cell by a publicly known cell fusion method to create the transgenic animal of the present invention.
[0377]Examples of the non-human mammal that can be used include bovine, swine, sheep, goat, rabbits, dogs, cats, guinea pigs, hamsters, mice, rats and the like. Above all, preferred are rodents, especially mice (e.g., C57BL/6 strain, DBA2 strain, etc. for a pure line and for a cross line, B6C3F1 strain, BDF1 strain, B6D2F1 strain, BALB/c strain, ICR strain, etc.) or rats (Wistar, SD, etc.) and the like, since they are relatively short in ontogeny and life cycle from a standpoint of creating model disease animals, and are easy in breeding.
[0378]"Mammals" in a recombinant vector that can be expressed in mammals include human etc. in addition to the aforesaid non-human mammals.
[0379]The exogenous DNA of the present invention refers to the DNA of the present invention that is once isolated and extracted from mammals, not the DNA of the present invention inherently possessed by the non-human mammals.
[0380]The mutant DNA of the present invention includes mutants resulting from variation (e.g., mutation, etc.) in the base sequence of the original DNA of the present invention, specifically DNAs resulting from base addition, deletion, substitution with other bases, etc. and further including abnormal DNA.
[0381]The abnormal DNA is intended to mean the DNA that expresses the abnormal protein of the present invention and exemplified by such a DNA that expresses a protein suppressing the functions of the normal protein of the present invention, or the like.
[0382]The exogenous DNA of the present invention may be any one of those derived from a mammal of the same species as, or a different species from, the mammal as the target animal. In transfecting the DNA of the present invention to the target animal, it is generally advantageous to use the DNA as a DNA construct in which the DNA is ligated downstream a promoter capable of expressing the DNA in the target animal. For example, in the case of transfecting the human DNA of the present invention, a DNA transgenic mammal that expresses the DNA of the present invention to a high level can be prepared by microinjecting a DNA construct (e.g., vector, etc.) ligated with the human DNA of the present invention into a fertilized egg of the target mammal, e.g., a fertilized egg of mouse, downstream the various promoters capable of expressing the DNA derived from various mammals (e.g., rabbits, dogs, cats, guinea pigs, hamsters, rats, mice, etc.) having the DNA of the present invention highly homologous to the human DNA.
[0383]As expression vectors for the protein of the present invention, there are Escherichia coli-derived plasmids, Bacillus subtilis-derived plasmids, yeast-derived plasmids, bacteriophages such as λ phage, etc., retroviruses such as Moloney leukemia virus, etc., animal viruses such as vaccinia virus, baculovirus, etc. Of these vectors, Escherichia coli-derived plasmids, Bacillus subtilis-derived plasmids, yeast-derived plasmids, etc. are preferably used.
[0384]Examples of these promoters for regulating the DNA expression include (i) promoters for DNA derived from viruses (e.g., simian virus, cytomegalovirus, Moloney leukemia virus, JC virus, breast cancer virus, poliovirus, etc.), and (ii) promoters derived from various mammals (human, rabbits, dogs, cats, guinea pigs, hamsters, rats, mice, etc.), for example, promoters of albumin, insulin II, uroplakin II, elastase, erythropoietin, endothelin, muscular creatine kinase, glial fibrillary acidic protein glutathione S-transferase, platelet-derived growth factor β, keratins K1, K10 and K14, collagen types I and II, cyclic AMP-dependent protein kinase βI subunit, dystrophin, tartarate-resistant alkaline phosphatase, atrial natriuretic factor, endothelial receptor tyrosine kinase (generally abbreviated as Tie2), sodium-potassium adenosine triphosphorylase (Na, K-ATPase), neurofilament light chain, metallothioneins I and IIA, metalloproteinase 1 tissue inhibitor, MHC class I antigen (H-2L), H-ras, renin, dopamine β-hydroxylase, thyroid peroxidase (TPO), polypeptide chain elongation factor 1α(EF-1α), β actin, α and β myosin heavy chains, myosin light chains 1 and 2, myelin base protein, thyroglobulins, Thy-1, immunoglobulins, H-chain variable region (VNP), serum amyloid component P, myoglobin, troponin C, smooth muscle α actin, preproencephalin A, vasopressin, etc. Among them, cytomegalovirus promoters, human peptide elongation factor 1α (EF-1α) promoters, human and chicken β actin promoters etc., which can achieve high expression in the whole body, are preferred.
[0385]It is preferred that the vectors described above have a sequence for terminating the transcription of the desired messenger RNA in the DNA transgenic animal (generally called a terminator); for example, a sequence of each DNA derived from viruses and various mammals. SV40 terminator of the simian virus, etc. are preferably used.
[0386]In addition, for the purpose of increasing the expression of the desired exogenous DNA to a higher level, the splicing signal and enhancer region of each DNA, a portion of the intron of an eukaryotic DNA may also be ligated at the 5, upstream of the promoter region, or between the promoter region and the translational region, or at the 3' downstream of the translational region, depending upon purposes.
[0387]The normal translational region of the protein of the present invention can be prepared as the whole or a part of genomic DNA from DNA derived from liver, kidney, thyroid cells, fibroblasts etc. derived from humans or mammals (for example, rabbit, dog, cat, guinea pig, hamster, rat, mouse etc.) and a wide variety of commercial DNA libraries, or from complementary DNA as a starting material prepared by a known method from RNA derived from liver, kidney, thyroid cells, fibroblasts etc. As the extraneous abnormal DNA, a translational region can be prepared by point mutation of the normal translational region of the polypeptide obtained from the above cells or tissues.
[0388]The translational region can be prepared, as a DNA construct capable of being expressed in the transgenic animal, by a conventional DNA engineering technique, in which the DNA is ligated downstream the aforesaid promoter and if desired, upstream the translation termination site.
[0389]The exogenous DNA of the present invention is transfected at the fertilized egg cell stage in a manner such that the DNA is certainly present in all the germinal cells and somatic cells of the target mammal. The fact that the exogenous DNA of the present invention is present in the germinal cells of the animal prepared by DNA transfection means that all offspring of the prepared animal will maintain the exogenous DNA of the present invention in all of the germinal cells and somatic cells thereof. The offspring of the animal that inherits the exogenous DNA of the present invention also have the exogenous DNA of the present invention in all of the germinal cells and somatic cells thereof.
[0390]The non-human mammal, in which the normal exogenous DNA of the present invention has been transfected can be passaged as the DNA-bearing animal under ordinary rearing environment, by confirming that the exogenous DNA is stably retained by mating.
[0391]By the transfection of the exogenous DNA of the present invention at the fertilized egg cell stage, the DNA is retained to be excess in all of the germinal and somatic cells of the target mammal. The fact that the exogenous DNA of the present invention is excessively present in the germinal cells of the prepared animal after transfection means that all of the offspring of the animal prepared have the exogenous DNA of the present invention excessively in all of the germinal cells and somatic cells thereof. The offspring of the animal of this kind that inherits the exogenous DNA of the present invention excessively have the DNA of the present invention in all of the germinal cells and somatic cells thereof.
[0392]By obtaining a homozygotic animal having the transfected DNA in both of homologous chromosomes and mating a male and female of the animal, all offspring can be passaged to excessively retain the DNA.
[0393]In a non-human mammal bearing the normal DNA of the present invention, the normal DNA of the present invention is expressed to a high level, and may eventually develop the hyperfunction of the protein of the present invention by promoting the functions of endogenous normal DNA. Therefore, the animal can be utilized as a pathologic model animal for such a disease. Specifically, using the normal DNA transgenic animal of the present invention, it becomes possible to elucidate the hyperfunction of the protein of the present invention and to clarify the pathological mechanism of the disease associated with the protein of the present invention and to determine how to treat these diseases.
[0394]Furthermore, since a mammal transfected with the exogenous normal DNA of the present invention exhibits an increasing symptom of the librated protein of the present invention, the animal is usable for screening of therapeutic agents agent for the disease associated with the protein of the present invention.
[0395]On the other hand, non-human mammal having the exogenous abnormal DNA of the present invention can be passaged under normal breeding conditions as the DNA-bearing animal by confirming the stable retaining of the exogenous DNA via crossing. In addition, the objective exogenous DNA can be utilized as a starting material by inserting the objective exogenous DNA into the plasmid described above. The DNA construct with a promoter can be prepared using conventional DNA engineering techniques. The transfection of the abnormal DNA of the present invention at the fertilized egg cell stage is preserved to be present in all of the germinal and somatic cells of the mammals to be targeted. The fact that the abnormal DNA of the present invention is present in the germinal cells of the animal after DNA transfection means that all of the offspring of the prepared animal have the abnormal DNA of the present invention in all of the germinal and somatic cells. The offspring of such an animal that inherits the exogenous DNA of the present invention has the abnormal DNA of the present invention in all the germinal and somatic cells. A homozygous animal having the introduced DNA on both of homologous chromosomes can be acquired and then by mating these male and female animals, all the offspring can be bred to have the DNA.
[0396]Since the non-human mammal having the abnormal DNA of the present invention expresses the abnormal DNA of the present invention at a high level, the animal may cause the function inactive type inadaptability of the protein of the present invention by inhibiting the functions of the endogenous normal DNA, and can be utilized as its disease model animal. For example, using the abnormal DNA-transferred animal of the present invention, it is possible to elucidate the mechanism of the function inactive type inadaptability of the protein of the present invention and to study a method for treatment of this disease.
[0397]In its specific applicability, the transgenic animal of the present invention expressing the abnormal DNA of the present invention to a high level is also expected to serve as a model for the elucidation of the mechanism of the functional inhibition (dominant negative effect) of a normal protein by the abnormal protein of the present invention in the function inactive type inadaptability of the protein of the present invention.
[0398]A mammal bearing the abnormal exogenous DNA of the present invention is also expected to serve for screening a candidate drug for the treatment of the function inactive type inadaptability of the protein of the present invention, since the protein of the present invention is increased in such an animal in its free form.
[0399]Other potential applicability of the two kinds of the transgenic animals described above includes:
[0400](i) use as a cell source for tissue culture;
[0401](ii) elucidation of the association with a peptide that is specifically expressed or activated by the protein of the present invention, through direct analysis of DNA or RNA in tissue of the DNA transgenic animal of the present invention or by analysis of the peptide tissue expressed by the DNA;
[0402](iii) research in the function of cells derived from tissues that are cultured usually only with difficulty, using cells of tissue bearing the DNA cultured by a standard tissue culture technique;
[0403](iv) screening for a drug that enhances the functions of cells using the cells described in (iii) above; and,
[0404](v) isolation and purification of the variant protein of the present invention and preparation of an antibody thereto.
[0405]Furthermore, clinical conditions of a disease associated with the protein of the present invention, including the function inactive type inadaptability of the protein of the present invention can be determined using the DNA transgenic animal of the present invention. Also, pathological findings on each organ in a disease model associated with the protein of the present invention can be obtained in more detail, leading to the development of a new method for treatment as well as the research and therapy of any secondary diseases associated with the disease.
[0406]It is also possible to obtain a free DNA-transfected cell by withdrawing each organ from the DNA transgenic animal of the present invention, mincing the organ and degrading with a proteinase such as trypsin, etc., followed by establishing the line of culturing or cultured cells. Furthermore, the DNA transgenic animal of the present invention can serve as identification of cells capable of producing the protein of the present invention, and as studies on association with apoptosis, differentiation or propagation or on the mechanism of signal transduction in these properties to inspect any abnormality therein. Thus, the DNA transgenic animal of the present invention can provide an effective research material for the protein of the present invention and for elucidating the function and effect thereof.
[0407]To develop pharmaceuticals for the treatment of diseases associated with the protein of the present invention, including the function inactive type inadaptability of the protein of the present invention, using the DNA transgenic animal of the present invention, an effective and rapid method for screening the pharmaceuticals for the treatment of diseases can be provided by using the method for inspection and the method for quantification, etc. described above. It is also possible to investigate and develop a method for DNA therapy for the treatment of diseases associated with the protein of the present invention, using the DNA transgenic animal of the present invention or a vector capable of expressing the exogenous DNA of the present invention.
[7] Knockout Animal
[0408]The present invention provides a non-human mammal embryonic stem cell bearing the DNA of the present invention inactivated and a non-human mammal deficient in expressing the DNA of the present invention.
[0409]Thus, the present invention provides:
[0410](1) a non-human mammal embryonic stem cell in which the DNA of the present invention is inactivated;
[0411](2) the embryonic stem cell according to (1), wherein the DNA is inactivated by introducing a reporter gene (e.g., β-galactosidase gene derived from Escherichia coli);
[0412](3) the embryonic stem cell according to (1), which is resistant to neomycin;
[0413](4) the embryonic stem cell according to (1), wherein the non-human mammal is a rodent;
[0414](5) an embryonic stem cell according to (4), wherein the rodent is mouse;
[0415](6) a non-human mammal deficient in expressing the DNA of the present invention, wherein the DNA of the present invention is inactivated;
[0416](7) the non-human mammal according to (6), wherein the DNA is inactivated by inserting a reporter gene (e.g., β-galactosidase derived from Escherichia coli) therein and the reporter gene is capable of being expressed under the control of a promoter for the DNA of the present invention;
[0417](8) the non-human mammal according to (6), which is a rodent;
[0418](9) the non-human mammal according to (8), wherein the rodent is mouse; and
[0419](10) a method for screening a compound or its salt that promotes or inhibits the promoter activity for the DNA of the present invention, which comprises administering a test compound to the animal of (7) and detecting expression of the reporter gene.
[0420]The non-human mammalian embryonic stem cell, in which the DNA of the present invention is inactivated, refers to a non-human mammalian embryonic stem cell that suppresses the ability of the non-human mammalian to express the DNA by artificially mutating the DNA of the present invention possessed in the non-human mammal, or the DNA has no substantial ability to express the protein of the present invention (hereinafter sometimes referred to as the knockout DNA of the present invention) by substantially inactivating the activities of the protein of the present invention encoded by the DNA (hereinafter merely referred to as ES cell).
[0421]As the non-human mammalian, the same examples as described above apply.
[0422]Techniques for artificially mutating the DNA of the present invention include deletion of a part or all of the DNA sequence and insertion of, or substitution with, other DNA, e.g., by genetic engineering. By these variations, the knockout DNA of the present invention may be prepared, for example, by shifting the reading frame of a codon or by disrupting the function of a promoter or exon.
[0423]Specifically, the non-human mammalian embryonic stem cell, in which the DNA of the present invention is inactivated (hereinafter merely referred to as the ES cell with the DNA of the present invention inactivated or the knockout ES cell of the present invention), can be obtained by, for example, isolating the DNA of the present invention possessed by the target non-human mammal, inserting a DNA strand (hereinafter simply referred to as targeting vector) having a DNA sequence constructed so as to eventually destroy the gene by inserting into its exon site a chemical resistant gene such as a neomycin resistant gene or a hygromycin resistant gene, or a reporter gene such as lacZ (β-galactosidase gene) or cat (chloramphenicol acetyltransferase gene), etc. thereby destroying the functions of exon, or by inserting into the intron site between exons a DNA sequence which terminates gene transcription (e.g., polyA-added signal, etc.) thereby disabling the synthesis of complete messenger RNA, into a chromosome of the animal cells by, e.g., homologous recombination. The thus obtained ES cells are analyzed by the Southern hybridization using as a probe a DNA sequence on or near the DNA of the present invention, or by PCR using as primers a DNA sequence on the targeting vector and another DNA sequence near the DNA of the present invention which is not included in the targeting vector, and the knockout ES cell of the present invention is selected.
[0424]The parent ES cells to inactivate the DNA of the present invention by homologous recombination, etc. may be of a strain already established as described above, or may be originally established in accordance with a modification of the known method by Evans and Kaufman supra. For example, in the case of mouse ES cells, currently it is common practice to use ES cells of the 129 strain. However, since their immunological background is obscure, the C57BL/6 mouse or the BDF1 mouse (F1 hybrid between C57BL/6 and DBA/2), wherein the low ovum collection per C57BL/6 mouse or C57BL/6 has been improved by crossing with DBA/2, may be preferably used, instead of obtaining a pure line of ES cells with the clear immunological genetic background. The BDF1 mouse is advantageous in that when a pathologic model mouse is generated using ES cells obtained therefrom, the genetic background can be changed to that of the C57BL/6 mouse by back-crossing with the C57BL/6 mouse, since its background is of the C57BL/6 mouse, as well as being advantageous in that ovum availability per animal is high and ova are robust.
[0425]In establishing ES cells, blastocytes of 3.5 days after fertilization are commonly used. A large number of early stage embryos may be acquired more efficiently, by collecting the embryos of the 8-cell stage and using the same after culturing until the blastocyte stage.
[0426]Although the ES cells used may be of either sex, male ES cells are generally more convenient for generation of a germ cell line chimera and are therefore preferred. It is desirable to identify sexes as soon as possible also in order to save painstaking culture time.
[0427]As an example of the method for sex identification of the ES cell, mention may be made of a method in which a gene in the sex-determining region on the Y-chromosome is amplified by PCR and detected. When this method is used, ES cells (about 50 cells) corresponding to almost 1 colony are sufficient, whereas karyotype analysis hitherto required about 106 cells; therefore, the first selection of ES cells at the early stage of culture can be based on sex identification, and male cells can be selected early, which saves a significant amount of time at the early stage of culture.
[0428]Second selection can be achieved by, for example, number of chromosome confirmation by the G-banding method. It is usually desirable that the chromosome number of the obtained ES cells be 100% of the normal number. However, when it is difficult to obtain the cells having the normal number of chromosomes due to physical operation etc. in cell establishment, it is desirable that the ES cell be again cloned to a normal cell (e.g., in mouse cells having the number of chromosomes being 2n=40) after the gene of the ES cells is rendered knockout.
[0429]Although the embryonic stem cell line thus obtained shows a very high growth potential, it must be subcultured with great care, since it tends to lose its ontogenic capability. For example, the embryonic stem cell line is cultured at about 37° C. in a carbon dioxide incubator (preferably about 5% carbon dioxide and about 95% air, or about 5% oxygen, about 5% carbon dioxide and about 90% air) in the presence of LIF (1-10000 U/ml) on appropriate feeder cells such as STO fibroblasts, treated with a trypsin/EDTA solution (normally about 0.001 to about 0.5% trypsin/about 0.1 to 5 mM EDTA, preferably about 0.1% trypsin/about 1 mM EDTA) at the time of passage to obtain separate single cells, which are then seeded on freshly prepared feeder cells. This passage is normally conducted every 1 to 3 days; it is desirable that cells be observed at passage and cells found to be morphologically abnormal in culture, if any, be abandoned.
[0430]By allowing ES cells to reach a high density in mono-layers or to form cell aggregates in suspension under appropriate conditions, it is possible to differentiate them to various cell types, for example, parietal and visceral muscles, cardiac muscle or the like [M. J. Evans and M. H. Kaufman, Nature, 292, 154, 1981; G. R. Martin, Proc. Natl. Acad. Sci. U.S.A., 78, 7634, 1981; T. C. Doetschman et al., Journal of Embryology Experimental Morphology, 87, 27, 1985]. The cells deficient in expression of the DNA of the present invention, which are obtainable from the differentiated ES cells of the present invention, are useful for studying the functions of the protein of the present invention or the protein of the present invention in vitro cytologically or molecular biologically.
[0431]The non-human mammal deficient in expression of the DNA of the present invention can be identified from a normal animal by measuring the amount of mRNA in the subject animal by a publicly known method, and indirectly comparing the levels of expression.
[0432]As the non-human mammal, the same examples supra apply.
[0433]With respect to the non-human mammal deficient in expression of the DNA of the present invention, the DNA of the present invention can be made knockout by transfecting a targeting vector, prepared as described above, to mouse embryonic stem cells or mouse oocytes thereof, and conducting homologous recombination in which a targeting vector DNA sequence, wherein the DNA of the present invention is inactivated by the transfection, is replaced with the DNA of the present invention on a chromosome of a mouse embryonic stem cell or mouse oocyte.
[0434]The cells with the DNA of the present invention in which the DNA of the present invention is rendered knockout can be identified by the Southern hybridization analysis using as a probe a DNA sequence on or near the DNA of the present invention, or by PCR analysis using as primers a DNA sequence on the targeting vector and another DNA sequence which is not included in the DNA of the present invention derived from mouse, which is used as the targeting vector. When non-human mammalian embryonic stem cells are used, the cell line wherein the DNA of the present invention is inactivated is cloned by homologous recombination; the resulting cloned cell line is injected to, e.g., a non-human mammalian embryo or blastocyte, at an appropriate stage such as the 8-cell stage. The resulting chimeric embryos are transplanted to the uterus of the pseudo-pregnant non-human mammal. The resulting animal is a chimeric animal composed of both cells having the normal locus of the DNA of the present invention and those having an artificially mutated locus of the DNA of the present invention.
[0435]When some germ cells of the chimeric animal have a mutated locus of the DNA of the present invention, an individual, in which all tissues are composed of cells having an artificially mutated locus of the DNA of the present invention, can be selected from a series of offspring obtained by crossing between such a chimeric animal and a normal animal, e.g., by coat color identification, etc. The individuals thus obtained are normally deficient in heterozygous expression of the protein of the present invention. The individuals deficient in homozygous expression of the protein of the present invention can be obtained from offspring of the intercross between the heterozygotes.
[0436]When an oocyte is used, a DNA solution may be injected, e.g., to the prenucleus by microinjection thereby obtaining a transgenic non-human mammal having a targeting vector introduced into its chromosome. From such transgenic non-human mammals, those having a mutation at the locus of the DNA of the present invention can be obtained by selection based on homologous recombination.
[0437]As described above, individuals wherein the DNA of the present invention is rendered knockout permit passage rearing under ordinary rearing conditions, after it is confirmed that in the animal individuals obtained by their crossing, the DNA has been knockout.
[0438]Furthermore, the genital system may be obtained and maintained by conventional methods. That is, by crossing male and female animals each having the inactivated DNA, homozygote animals having the inactivated DNA in both loci can be obtained. The homozygotes thus obtained may be reared so that one normal animal and two or more homozygotes are produced from a mother animal to efficiently obtain such homozygotes. By crossing male and female heterozygotes, homozygotes and heterozygotes having the inactivated DNA are proliferated and passaged.
[0439]The non-human mammalian embryonic stem cell, in which the DNA of the present invention is inactivated, is very useful for preparing a non-human mammal deficient in expression of the DNA of the present invention.
[0440]Since the non-human mammal, in which the DNA of the present invention fails to express, lacks various biological activities induced by the protein of the present invention, such an animal can be a disease model suspected of inactivated biological activities of the protein of the present invention and thus, offers an effective study to investigate causes for and therapy for these diseases.
[7a] Method for Screening of Compounds Having Therapeutic/Prophylactic Effects for Diseases Caused by Deficiency, Damages, etc. of the DNA of the Present Invention
[0441]The non-human mammal deficient in expression of the DNA of the present invention can be used to screen compounds having therapeutic/prophylactic effects for diseases caused by deficiency, damages, etc. of the DNA of the present invention.
[0442]That is, the present invention provides a method for screening of a compound or its salt having therapeutic/prophylactic effects for diseases caused by deficiency, damages, etc. of the DNA of the present invention, which comprises administering a test compound to the non-human mammal deficient in expression of the DNA of the present invention, and observing and measuring a change having occurred in the animal.
[0443]As the non-human mammal deficient in expression of the DNA of the present invention used for the screening method, the same examples as given hereinabove apply.
[0444]Examples of the test compounds include peptides, proteins, non-peptide compounds, synthetic compounds, fermentation products, cell extracts, plant extracts, animal tissue extracts, blood plasma, etc. and these compounds may be novel compounds or publicly known compounds.
[0445]Specifically, the non-human mammal deficient in the expression of the DNA of the present invention is treated with a test compound, comparison is made with an intact animal for control and a change in each organ, tissue, disease conditions, etc. of the animal is used as an indicator to assess the therapeutic/prophylactic effects of the test compound.
[0446]For treating an animal to be tested with a test compound, for example, oral administration, intravenous injection, etc. are applied and the treatment is appropriately selected depending upon conditions of the test animal, properties of the test compound, etc. Furthermore, the amount of a test compound administered can be appropriately selected depending on administration route, nature of the test compound, or the like.
[0447]For example, when a compound having a therapeutic effect on hyperlipemia is screened, a test compound is administered into a non-human mammalian animal deficient in expressing DNA encoding the protein A of the present invention, raised with common feed or cholesterol-containing common feed, and then the amount of total bile acid in feces or total serum cholesterol in the animal is measured with time.
[0448]For example, when a compound having a prophylactic/therapeutic effect on renal insufficiency is screened, a test compound is administered into a non-human mammalian animal deficient in expressing DNA encoding the protein B of the present invention, and then the amount of blood creatine or urine protein in the animal is measured with time.
[0449]For example, when a compound having a therapeutic effect on diabetics is screened, a non-human mammalian animal deficient in expressing DNA encoding the protein C of the present invention is subjected to a sugar loading treatment, a test compound is administered before or after the sugar loading treatment, and blood sugar level, body weight change, etc. of the animal are measured with time.
[0450]For example, when a compound having a prophylactic/therapeutic effect on chronic articular rheumatism is screened, a test compound is administered into a non-human mammalian animal deficient in expressing DNA encoding the protein D of the present invention, and then the volume of a swelling in a joint in the animal is measured with time, or the damage in the joint is evaluated by X-ray, MRI. histological techniques etc.
[0451]The compound obtained by the above screening is a compound selected from the test compounds described above, and has therapeutic/prophylactic effects on diseases caused by deficiency, damages, etc. of the protein of the present invention, and can thus be used as a safe and low toxic drug for the treatment/prevention, etc. for these diseases. A compound derived from the compound obtained by the screening can also be similarly used.
[0452]The compound obtained by the screening method may form a salt, and as the salts of the compound, there may be used salts with physiologically acceptable acids (e.g., inorganic acids or organic acids) or bases (e.g., alkali metals), preferably physiologically acceptable acid addition salts. Examples of such salts are salts with inorganic acids (e.g., hydrochloric acid, phosphoric acid, hydrobromic acid, sulfuric acid), salts with organic acids (e.g., acetic acid, formic acid, propionic acid, fumaric acid, maleic acid, succinic acid, tartaric acid, citric acid, malic acid, oxalic acid, benzoic acid, methanesulfonic acid, benzenesulfonic acid) and the like.
[0453]A medicine comprising the compound or salts thereof obtained by the above screening method may be manufactured in a manner similar to the method for preparing the medicine comprising the protein of the present invention described hereinabove.
[0454]Since the medicine thus obtained is safe and low toxic, it can be administered to humans or other mammals (e.g., rat, mouse, guinea pig, rabbit, sheep, swine, bovine, horse, cat, dog, monkey, etc.).
[0455]The dose of the above compound or its salt may vary depending on its action, target disease, subject to be administered, route for administration, etc. When the compound is orally administered, the compound is administered to adult (as 60 kg) as a patient with hyperlipemia generally in a daily dose of approximately 0.1 mg to 100 mg, preferably approximately 1.0 mg to 50 mg, more preferably approximately 1.0 to 20 mg. When the compound is parenterally administered, a single dose of the compound may vary depending on subject to be administered, target disease, etc. When the compound is administered in the form of an injection to adult (as 60 kg body weight) as a patient with hyperlipemia, it is convenient to administer the compound by intravenous injection generally in a daily dose of approximately 0.01 to 30 mg, preferably approximately 0.1 to 20 mg, more preferably approximately 0.1 to 10 mg. For other animal species, the corresponding dose as converted per 60 kg weight can be administered.
[7b] Method of Screening a Compound that Promotes or Inhibits the Activities of a Promoter for the DNA of the Present Invention
[0456]The present invention provides a method of screening a compound or its salt that promotes or inhibits the activities of a promoter for the DNA of the present invention, which comprises administering a test compound to a non-human mammal deficient in expression of the DNA of the present invention and detecting expression of the reporter gene.
[0457]In the screening method described above, the non-human mammal deficient in expression of the DNA of the present invention is selected from the aforesaid non-human mammal deficient in expression of the DNA of the present invention for an animal, in which the DNA of the present invention is inactivated by introducing a reporter gene and the reporter gene can be expressed under the control of a promoter for the DNA of the present invention.
[0458]The same examples given above for the test compound apply to the test compound.
[0459]As the reporter gene, the same specific examples given above apply to the reporter gene, with β-galactosidase (lacZ), soluble alkaline phosphatase gene, luciferase gene, etc. being preferred.
[0460]In the non-human mammal deficient in expression of the DNA of the present invention wherein the DNA of the present invention is substituted with a reporter gene, the reporter gene is present under the control of a promoter for the DNA of the present invention. Thus, the activity of the promoter can be detected by tracing the expression of a substance encoded by the reporter gene.
[0461]For example, when a part of the DNA region encoding the protein of the present invention is substituted with, e.g., β-galactosidase gene (lacZ) derived from Escherichia coli, β-galactosidase is expressed in a tissue where the protein of the present invention should originally be expressed, in place of the protein of the present invention. Thus, the expression state of the protein of the present invention can be readily observed in vivo in an animal, by staining with a reagent, e.g., 5-bromo-4-chloro-3-indolyl-β-galactopyranoside (X-gal), which is a substrate for β-galactosidase. Specifically, a mouse deficient in the protein of the present invention, or its tissue section, is fixed with glutaraldehyde, etc. After washing with phosphate buffered saline (PBS), the system is reacted with a staining solution containing X-gal at room temperature or about 37° C. for approximately 30 minutes to 1 hour. After the β-galactosidase reaction is terminated by washing the tissue preparation with 1 mM EDTA/PBS solution, the color formed is observed. Alternatively, mRNA encoding lacZ may be detected in a conventional manner.
[0462]The compound or salts thereof obtained using the screening methods supra are compounds selected from the test compounds described above, which promote or inhibit the promoter activity for the DNA of the present invention.
[0463]The compound obtained by the screening methods may be in the form of salts. The salts of the compound used are salts with physiologically acceptable acids (e.g., inorganic acids) or bases (e.g., organic acids), and physiologically acceptable acid addition salts are preferred. Examples of such salts are salts with inorganic acids (e.g., hydrochloric acid, phosphoric acid, hydrobromic acid, sulfuric acid), salts with organic acids (e.g., acetic acid, formic acid, propionic acid, fumaric acid, maleic acid, succinic acid, tartaric acid, citric acid, malic acid, oxalic acid, benzoic acid, methanesulfonic acid, benzenesulfonic acid) and the like.

[0486]As the protein D used in the method of determining ligands, any material comprising the protein D of the present invention or the partial peptide of the present invention may be used, but the protein produced in a large amount by animal cells is appropriate.
[0487]The protein D of the present invention can be manufactured by the expression method described above, preferably by expressing DNA encoding the protein D in mammalian or insect cells. As DNA fragments encoding the desired portion of the protein, complementary DNA is generally used but not necessarily limited thereto. For example, gene fragments or synthetic DNA may also be used. For introducing a DNA fragment encoding the protein D of the present invention into host animal cells and efficiently expressing the same, it is preferred to insert the DNA fragment downstream a polyhedrin promoter of nuclear polyhedrosis virus (NPV), which is a baculovirus having insect hosts, an SV40-derived promoter, a retrovirus promoter, a metallothionein promoter, a human heat shock promoter, a cytomegalovirus promoter, an SRα promoter or the like. The amount and quality of the channel expressed can be determined by a publicly known method. For example, this determination can be made by the method described in the literature (Nambi, P., et al., J. Biol. Chem., 267, 19555-19559 (1992)).
[0488]Accordingly, the subject containing the protein D of the present invention, its partial peptides or salts thereof in the method for determining the ligand according to the present invention may be the protein D, its partial peptides or salts thereof purified by publicly known methods, cells containing the protein D, or membrane fractions of such cells.

[0490]The cells containing the protein D of the present invention are host cells that have expressed the protein D. As the host cells, Escherichia coli, Bacillus subtilis, yeast, insect cells, animal cells and the like are used.
[0491]The cell membrane fraction refers to a fraction abundant in cell membrane obtained by cell disruption and subsequent fractionation by a publicly known method. Cell disruption methods include cell squashing using a Potter-Elvehjem homogenizer, disruption using a Waring blender or Polytron (manufactured by Kinematica Inc.), disruption by ultrasonication, and disruption by cell spraying through thin nozzles under an increased pressure using a French press or the like. Cell membrane fractionation is effected mainly by fractionation using a centrifugal force, such as centrifugation for fractionation and density gradient centrifugation. For example, cell disruption fluid is centrifuged at a low speed (500 rpm to 3,000 rpm) for a short period of time (normally about 1 to about 10 minutes), and the resulting supernatant is then centrifuged at a higher speed (15,000 rpm to 30,000 rpm) normally for 30 minutes to 2 hours. The precipitate thus obtained is used as the membrane fraction. The membrane fraction is rich in the protein D expressed and membrane components such as cell-derived phospholipids and membrane proteins.
[0492]The amount of the protein D in the protein D-containing cells or membrane fraction is preferably 103 to 108 molecules per cell, more preferably 105 to 107 molecules per cell. As the amount of expression increases, the ligand binding activity per unit of membrane fraction (specific activity) increases so that not only the highly sensitive screening system can be constructed but also large quantities of samples can be assayed with the same lot.
[0493]To perform the methods (i) through (iii) supra for determination of a ligand to the protein D of the present invention or its salt, an appropriate protein D fraction and a labeled test compound are required.
[0494]The protein D fraction is preferably a fraction of naturally occurring protein D or a recombinant channel fraction having an equivalent activity to that of the natural protein. Herein, the term "equivalent activity" is intended to mean a ligand binding activity, a cation channel activity or the like that is equivalent to that possessed by the naturally occurring protein.
[0495]Preferred examples of labeled test compounds include angiotensin, bombesin, canavinoid, cholecystokinin, glutamine, serotonin, melatonin, neuropeptide Y, opioid, purines, vasopressin, oxytocin, PACAP (e.g., PACAP27, PACAP38), secretin, glucagon, calcitonin, adrenomedulin, somatostatin, GHRH, CRF, ACTH, GRP, PTH, VIP (vasoactive intestinal polypeptide), somatostatin, dopamine, motilin, amylin, bradykinin, CGRP (calcitonin gene-related peptide), leukotrienes, pancreastatin, prostaglandins, thromboxane, adenosine, adrenaline, a chemokine superfamily (e.g., CXC chemokine subfamily such as IL-8, GROα, GROβ, GROγ, NAP-2, ENA-78, GCP-2, PF4, IP10, Mig, PBSF/SDF-1, etc.; CC chemokine subfamily such as MCAF/MCP-1, MCP-2, MCP-3, MCP-4, eotaxin, RANTES, MIP1-α, MIP-1β, HCC-1, MIP-3α/LARC, MIP-3β/ELC, I-309, TARC, MIPF-1, MIPF-2/eotaxin-2, MDC, DC-CK1/PARC, SLC, etc.; C chemokine subfamily such as lymphotactin; and CX3C chemokine subfamily such as/fractalkine, etc.), endothelin, enterogastrin, histamin, neurotensin, TRH, pancreatic polypeptide, galanin, lysophosphatidic acid (LPA) or sphingosine 1-phosphate, vanilloid, nucleotide etc.), which are labeled with [3H], [125I], [14C], [35S], etc.
[0496]Specifically, the ligand to the protein D of the present invention or its salt is determined by the following procedures. First, a standard channel preparation is prepared by suspending cells containing the protein D of the present invention or the membrane fraction thereof in a buffer appropriate for use in the determination method. Any buffer can be used so long as it does not inhibit the ligand-protein D binding, such buffers including a phosphate buffer or a Tris-HCl buffer having pH of 4 to 10 (preferably pH of 6 to 8). For the purpose of minimizing non-specific binding, a surfactant such as CHAPS, TWEEN-80® (Polyoxyethylene (20) Sorbitan Monooleate) (manufactured by Kao-Atlas Inc.), digitonin or deoxycholate, and various proteins such as bovine serum albumin or gelatin, may optionally be added to the buffer. Further for the purpose of suppressing the degradation of the receptors or ligands by proteases, a protease inhibitor such as PMSF, leupeptin, E-64 (manufactured by Peptide Institute, Inc.) and pepstatin may also be added. A given amount (5,000 to 500,000 cpm) of the test compound labeled with [3H], [125I], [14C], [35S] or the like is added to 0.01 ml to 10 ml of the protein solution. To determine the amount of non-specific binding (NSB), a reaction tube containing an unlabeled test compound in large excess is also prepared. The reaction is carried out at approximately 0 to 50° C., preferably about 4 to 37° C. for about 20 minutes to about 24 hours, preferably about 30 minutes to about 3 hours. After completion of the reaction, the reaction mixture is filtrated through glass fiber filter paper, etc. and washed with an appropriate volume of the same buffer. The residual radioactivity on the glass fiber filter paper is then measured by means of a liquid scintillation counter or γ-counter. A test compound exceeding 0 cpm in count obtained by subtracting nonspecific binding (NSB) from the total binding (B) (B minus NSB) can be selected as a ligand to the protein D of the present invention or its salt.
[0497]The method (iv) above for determination of a ligand to the protein D of the present invention or its salt can be performed as follows. The protein D-mediated cation channel activities (e.g., Ca2+ channel activity etc.) may be determined by a publicly known method, or using an assay kit commercially available. Specifically, cells containing the protein D are first cultured on a multi-well plate, etc. Prior to the ligand determination, the medium is replaced with fresh medium or with an appropriate non-cytotoxic buffer, followed by incorporation of a fluorescent Ca2+ probe (for example, Fura-2, Fuo-3 or the like) and subsequent measurement of fluorescence density by FLIPR (Molecular Devices, Ltd.) etc. for a given period of time in the presence of a test compound, etc. The kit of the present invention for determination of the ligand that binds to the protein D of the present invention or its salt comprises the protein D of the present invention or its salt, the partial peptide of the present invention or its salt, cells comprising the protein D of the present invention, or the membrane fraction of the cells containing the protein D of the present invention.

[0678]Using two primer DNAs, i.e. primer OF (SEQ ID NO: 3) and primer OR1 (SEQ ID NO: 4), human small intestine Marathon-Ready cDNA and human skeletal muscle Marathon-Ready cDNA (both of which were manufactured by Clontech) were subjected to primary PCR with Pyrobest DNA Polymerase (Takara Shuzo Co., Ltd.) under the following conditions (1) to (3):
[0679](1) reaction at 94° C. for 2 minutes,
[0680](2) 30 cycles each consisting of reaction at 98° C. for 10 seconds, at 68° C. for 30 seconds and at 72° C. for 3 minutes, and
[0681](3) reaction at 72° C. for 10 minutes.
[0682]Using the primary PCR product as a template, nested PCR was conducted with primer OF1 (SEQ ID NO: 5), primer OR (SEQ ID NO: 6) and Pyrobest DNA polymerase (Takara Shuzo Co., Ltd.) under the following conditions (4) to (6):
[0683](4) reaction at 94° C. for 2 minutes,
[0684](5) 35 cycles each consisting of reaction at 98° C. for 10 seconds, at 68° C. for 30 seconds, and at 72° C. for 3 minutes,
[0685](6) reaction at 72° C. for 10 minutes.
[0686]The resulting amplification product was cloned by using the Zero Blunt TOPO Cloning Kit (Invitrogen, Inc.), to give plasmid pCR-BluntII-TCH230.
[0687]This product was reacted with primer DNAs [primer SP6 (SEQ ID NO: 7), primer T7 (SEQ ID NO: 8), primer B1 (SEQ ID NO: 9), primer F1 (SEQ ID NO. 10)] and BigDye Terminator Cycle Sequencing Kit (Applied Biosystems), and the base sequence of the inserted cDNA fragment was determined by DNA sequencer ABI PRISM 3100 DNA analyzer (Applied Biosystems). The result indicated that the clone obtained from human small intestine cDNA had 1152-base sequence (SEQ ID NO. 11). The cDNA fragment (SEQ ID NO: 2) coded for a 377-amino acid sequence (SEQ ID NO. 1), and the protein having the amino acid sequence was designated human TCH230 (SEQ ID NO:1) protein.
[0688]A transformant having a plasmid comprising the cDNA fragment was designated Escherichia coli TOP10/pCR-BluntII-TCH230.
[0689]In the clone obtained from the human skeletal muscle cDNA, base substitution was recognized in one site (position 340 in the base sequence represented by SEQ ID NO. 11). This base substitution A340G is accompanied by amino acid substitution of Ile→Val, and it is considered that there is a possibility to be derived from single nucleotide polymorphisms (SNPs). The base sequence of the full-length cDNA possessed by this clone is shown in SEQ ID NO. 12, and the base sequence of ORF in this base sequence is shown in SEQ ID NO. 13. The amino acid sequence encoded by the base sequence represented by SEQ ID NO. 13 is shown in SEQ ID NO. 14.

Using this PCR reaction solution as a template, second PCR reaction was conducted with primer F00 and primer R00. The composition of the PCR reaction solution and reaction conditions are shown below.

This DNA was cloned into pCR-Blunt II-TOPO vector according to the protocol of the Zero Blunt TOPO PCR Cloning Kit (Invitrogen, Inc.). The product was transformed into Escherichia coli TOP10 competent cell (Invitrogen, Inc.), and clones having the cDNA insert fragment were selected in a kanamycin-containing LB agar medium to give transformants. The respective clones were cultured overnight in a kanamycin-containing LB medium, and plasmid DNAs were prepared by QIAwell 8 Plasmid Kit (Qiagen) to give pCR-BluntII-TCH200 plasmid clones #1, #2 and #3.

This base substitution C558A was not accompanied by amino acid substitution, and it is considered that the substitution is derived from single nucleotide polymorphisms (SNPs).
[0752]When homology with GENEMBL was conducted by using Blast P [Nucleic Acids Res., 25, 3389, 1997], the cDNA comprising the base sequence represented by SEQ ID NO: 67 was revealed to be a novel gene belonging to human vanilloid receptor (FIG. 11).

A mixture of 2 μg of plasmid DNA and transfection reagents was added to a 6 cm Petri dish on which 3×105 CHO dhfrcells had been plated before 24 hours. The cells were cultured for 1 day in MEMα medium (Invitrogen, Inc.) containing 10% bovine fetal serum (JRH Bioscience), and peeled off by treatment with trypsin, and the recovered cells were plated on a 96-well plate at a density of 10-50 cells/well. After 24 hours, 0.5 mg/ml geneticine (Invitrogen, Inc.) was added to the medium, and then the TCH230 expression cells were selected in a medium containing 0.5-1.0 mg/ml geneticine. 22 wells wherein one to three colonies had grownper well were cultured in a 6-well plate, and from the grown cells, total RNA was prepared by RNeasy Mini Kit or RNeasy 96 Kit (both available from Qiagen). The prepared total RNA was subjected to reverse transcription reaction by TaqMan Reverse Transcription Reagents (Applied Biosystems) to prepare cDNA. This was examined for the expression level of TCH230 by TaqMan PCR with primer TF (SEQ ID NO. 15) and primer TR (SEQ ID NO. 16) used in Example 2 and TaqMan probe T1 (SEQ ID NO. 17). The reaction involved a reaction at 50° C. for 2 minutes and at 95° C. for 10 minutes and 40 cycles each consisting of a reaction at 95° C. for 15 seconds and at 60° C. for 1 minute by using TaqMan Universal PCR Master Mix (Applied Biosystems) in ABI PRISM 7900 sequence detection system (Applied Biosystems), and simultaneously detection was carried out. As cell strains (polyclonal) highly expressing human TCH230 (SEQ ID NO:1) gene, clone Nos. 19 and 26 were selected. Each strain was inoculated into a 96-well plate at a density of 0.5 cell/well, and then cultured for 7 to 10 days in a medium containing geneticine, to give a monoclonal clone. Total RNA was prepared and the expression level of human TCH230 (SEQ ID NO:1) gene was measured by TaqMan PCR. As cell strains (monoclonal) expressing human TCH230 (SEQ ID NO:1), clone No. 19-6 were selected.

Construction of Human TCH212 (SEQ ID NO:42) Expression Vector
[0836]Human TCH212 (SEQ ID NO: 42) expression vector was constructed by the following method.
[0837]Using 10 ng of plasmid obtained in Example 7 as a template, PCR was conducted with primer 2120F (SEQ ID NO. 153) and primer 2120R (SEQ ID NO. 154) and KOD DNA Polymerase (Toyobo) under the following conditions (1) to (3). The 5'-terminal side primer 2120F and the 3'-terminal side primer 2120R were designed such that BamH I site and Not I site were added respectively to the 5'-terminal side for cloning into a vector.
[0838](1) reaction at 94° C. for 2 minutes,
[0839](2) 35 cycles each consisting of reaction at 94° C. for 15 seconds, at 60° C. for 30 seconds and at 68° C. for 3.5 minutes, and
[0840](3) reaction at 68° C. for 3 minutes.
[0841]The PCR reaction solution was subjected to gel electrophoresis, and a major band was purified. The PCR fragment thus obtained was digested with restriction enzymes Bam HI and Not I at 37° C. for 1 hour, and the reaction solution was subjected to gel electrophoresis and purified. The product was ligated to Bam HI site and Not I site of an animal cell expression vector pcDNA3.1(+) (Invitrogen, Inc.) by using Takara ligation kit ver. 2 (Takara Bio). This ligation reaction solution was used to transform a competent cell Escherichia coli JM109 (Takara Bio).
[0842]From a plurality of colonies thus obtained, a plasmid was prepared, and with respect to 2 clones wherein a fragment of about 3.5 kbp was confirmed to be inserted, the base sequence was reacted by using primer DNAs [primer BGH RV (SEQ ID NO. 124), primer T7 (SEQ ID NO: 8), primer A2 (SEQ ID NO: 48), primer B1 (SEQ ID NO: 49), primer B2 (SEQ ID NO: 50), primer F1 (SEQ ID NO: 51), primer F2 (SEQ ID NO: 52), primer F3 (SEQ ID NO: 53), primer F4 (SEQ ID NO: 54), primer F5 (SEQ ID NO: 55), primer R1 (SEQ ID NO: 56), primer R2 (SEQ ID NO: 57), primer R3 (SEQ ID NO: 58), primer R4 (SEQ ID NO: 59)] and BigDye Terminator Cycle Sequencing Kit (Applied Biosystems), and the base sequence was determined by DNA sequencer ABI PRISM 3100 DNA analyzer (Applied Biosystems). As a result, one-base substitution was observed in both the clones as compared with SEQ ID NO: 43. That is, in "clone 1", C at position 1185 in SEQ ID NO: 43 was changed into A, and in "clone 2", A at position 2509 was changed into T, and the change in both cases was a change to a termination codon on the frame.
[0843]Accordingly, the following correction was conducted. To introduce a termination codon on the same frame into an upstream from an initiation codon, the plasmid DNA in "clone 2" was cleaved with Nhe I, blunt-ended, re-cyclized by ligation and introduced into Escherichia coli JM109. The plasmid DNA in the resulting "modified clone 2" was cleaved with Bst EII and Not I, to remove a DNA fragment (about 1.1 kbp) having the one-base substitution at position 2509. Separately, the plasmid DNA in "clone 1" was cleaved with Bst EII and Not I to prepare a DNA fragment (about 1.1 kbp) of predetermined sequence. The above 2 DNA fragments were ligated and introduced into Escherichia coli JM109. After transformation, the transformant was cultured on agar medium at 30° C. for 2 days, and from a colony appearing on the second day, plasmid was extracted. This clone was determined for its base sequence in the same manner as described above, and confirmed to agree with SEQ ID NO: 43. The transformant having this plasmid was designated Escherichia coli JM109/pCDNA3.1 (+)-NheBlunt-TCH212.

[0850]The resulting amplification product was subjected to gel electrophoresis, and a fragment of about 1.1 kb was excised and purified by QIAquick Gel Extraction Kit (Qiagen).
