Crystal structure of the yeast Rsc2 BAH domain

Template:ABSTRACT PUBMED 23907388

Function

[RSC2_YEAST] Component of the chromatin structure remodeling complex (RSC), which is involved in transcription regulation and nucleosome positioning. RSC is responsible for the transfer of a histone octamer from a nucleosome core particle to naked DNA. The reaction requires ATP and involves an activated RSC-nucleosome intermediate. Remodeling reaction also involves DNA translocation, DNA twist and conformational change. As a reconfigurer of centromeric and flanking nucleosomes, RSC complex is required both for proper kinetochore function in chromosome segregation and, via a PKC1-dependent signaling pathway, for organization of the cellular cytoskeleton. This subunit is involved in meiotic sporulation through regulating IME2 expression, and is also essential for 2-micron plasmid maintenance and for normal REP1 protein localization.[1] [2] [3] [4] [5] [6] [7] [8]
