Article Abstract:
A meeting was sponsored last Sep, 1992 at Woods Hole, MA, by the Society of General Physiologists to understand how carrier proteins are able to achieve their transport functions via changes in conformation. In general, the research thrust regarding transport proteins is geared toward the elucidation of structure-function relationships, made possible by the rapidly developing techniques in molecular biology. Some of the recent developments in this field of protein chemistry are discussed.

Article Abstract:
The role played by desmosomal cadherin domains in plaque assembly and intermediate-sized filament (IF) anchorage during the formation of gap junctions was investigated. The results showed that the long splice form of the transmembranous region of desmocollin contains sufficient information to recruit desmoplakin and plakoglobin to gap junctions. Desmoglein did not elicit similar results, indicating that desmocollin plays an important role in the formation of desmosomal plaques.

Article Abstract:
The mechanism involved in the actin assembly was studied in the intracellular bacterial pathogen, Listeria. Listeria is a bacterial pathogen capable of causing fatal illnesses, especially in immune-compromised individuals. The organism contained an ActA protein responsible for assembling filamentous actin on its surface within the host cytoplasm. The N-terminal ActA domain facilitated actin nucleation and assembly of the comet tail.
