Ordered recruitment of transcription and chromatin remodeling factors to a cell cycle - and developmentally regulated promoter

Article Abstract:

A study was conducted to understand how adenosine triphosphate-dependent multisubunit chromatin remodeling complexes Swi/Snf and histone acetyltransferases SAGA are recruited to become promoters of gene activation as cells exit from mitosis. Results of experiments on budding yeast Saccharomyces cerevisiae suggest that Swi/Snf are recruited by the cycle-dependent transcription factor called Swi5p, This process then triggers the recruitment of SAGA by Swi/Snf to the mother cell.

Chromosomal cohesin forms a ring

Article Abstract:

Research points out that cohesin holds sister DNAs within a single ring and that all SMC protein complexes, like cohesin, allow passage of DNA inside two arms held together by Scc1-like bridges that open and close. This mechanism regulate the DNA packing within cells.
