Function
HTL1_YEAST Required for cell cycle progression through G2/M transition at temperatures higher than 33 degrees Celsius. 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. When associated with the RSC complex, may act coordinately with PKC1 to regulate G2/M transition. Together with LDB7, NPL6, RSC3, RSC30 components, defines a fungal-specific module within the RSC complex that plays a role in many cellular functions including the maintenance of cell wall integrity.[1] [2] [3]
