Polar localization of the MinD protein of Bacillus subtilis and its role in selection of the mid-cell division site

Article Abstract:

Rod-shaped bacteria divide cells by forming a ring of the protein FtsZ at mid-cell, and the MinCD protein is sequestered at cell poles to prevent further division. The Bacillus subtilis DivIVA protein controls how the MinCD behaves. Locating MinCD at cell poles also releases the next sites for division, yet this mechanism is entirely different from this action of the MinE protein, although both systems use MinCD as a division inhibitor.

mSin3-associated protein, mSds3, is essential for pericentric heterochromatin formation and chromosome segregation in mammalian cells

Article Abstract:

Research demonstrates that for proper chromosome segregation and distribution during cell division, mammalian cells require mSin3 protein and its associated histone acetyl transferases and deacetylases (HDACs), which initiate the cascade of pericentric heterochromatic-specific modifications for the process.

Division site selection protein DivIVA of Bacillus subtilis has a second distinct function in chromosome segregation during sporulation

Article Abstract:

Division site selection protein DivIVA of Bacillus subtilis has been found to have another distinct function in chromosome segregation during sporulation. Mutations in divIVA that separate the protein's role in sporulation from its vegetative function in cell division were isolated.
