DESCRIPTION

Also known as BAZ2B_HUMAN, BAZ2B, KIAA1476. Regulatory subunit of the ATP-dependent BRF-1 and BRF-5 ISWI chromatin remodeling complexes, which form ordered nucleosome arrays on chromatin and facilitate access to DNA during DNA-templated processes such as DNA replication, transcription, and repair (PubMed:28801535). Both complexes regulate the spacing of nucleosomes along the chromatin and have the ability to slide mononucleosomes to the center of a DNA template (PubMed:28801535). The BRF-1 ISWI chromatin remodeling complex has a lower ATP hydrolysis rate than the BRF-5 ISWI chromatin remodeling complex (PubMed:28801535). Chromatin reader protein, which may play a role in transcriptional regulation via interaction with ISWI (By similarity) (PubMed:10662543). Involved in positively modulating the rate of age-related behavioral deterioration (By similarity). Represses the expression of mitochondrial function-related genes, perhaps by occupying their promoter regions, working in concert with histone methyltransferase EHMT1 (By similarity). Component of the BRF-1 ISWI chromatin remodeling complex, at least composed of SMARCA1 and BAZ2B, which regulates the spacing of histone octamers on the DNA template to facilitate access to DNA (PubMed:28801535). Within the BRF-1 ISWI chromatin remodeling complex interacts with SMARCA1; the interaction is direct (PubMed:28801535). Component of the BRF-5 ISWI chromatin remodeling complex, at least composed of SMARCA5/SNF2H and BAZ2B, which regulates the spacing of histone octamers on the DNA template to facilitate access to DNA (PubMed:28801535). Within the BRF-5 ISWI chromatin remodeling complex interacts with SMARCA5/SNF2H; the interaction is direct (PubMed:28801535). Interacts with acetylated lysine residues on histone H1.4, H2A, H2B, H3 and H4 (in vitro). Interacts with EHMT1 (By similarity).
