Function
RUVB2_YEAST DNA helicase which participates in several chromatin remodeling complexes, including the SWR1 and the INO80 complexes. The SWR1 complex mediates the ATP-dependent exchange of histone H2A for the H2A variant HZT1 leading to transcriptional regulation of selected genes by chromatin remodeling. The INO80 complex remodels chromatin by shifting nucleosomes. Its ability to induce transcription of some phosphate-responsive genes is modulated by inositol polyphosphates. The INO80 complex is involved in DNA repair by associating to 'Ser-129' phosphorylated H2A histones as a response to DNA damage. During transcription may recruit SPT15/TBP to the TATA-boxes of involved genes. Required for box C/D and box H/ACA snoRNA accumulation and involved in pre-rRNA processing.[1] [2] [3] [4] [5] [6] [7] [8] [9]
