Chromatin structure-remodeling complex subunit RSC9

UniProtKB accession:  Q03124

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Component of the chromatin structure-remodeling complex (RSC), which is involved in transcription regulation and nucleosome positioning (PubMed:11931764, PubMed:8980231, PubMed:10025404, PubMed:10329629, PubMed:12072455). RSC is responsible for the transfer of a histone octamer from a nucleosome core particle to naked DNA (PubMed:10025404, PubMed:10329629). The reaction requires ATP and involves an activated RSC-nucleosome intermediate (PubMed:12183366). Remodeling reaction also involves DNA translocation, DNA twist and conformational change (PubMed:12183366). 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 (PubMed:12072455, PubMed:12697820). This subunit plays a role in transcriptional response to stress (PubMed:11931764). It is involved in both repression and activation of mRNAs regulated by the target of rapamycin (TOR) kinases, and in the synthesis of rRNA (PubMed:11931764, PubMed:10329629).
