BAZ2B
Function
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).
Sequence Similarities
Belongs to the WAL family.
Tissue Specificity
Expressed at varying levels in several tissues, whereas a smaller transcript was expressed specifically in testis.
