Involved in chromatin-remodeling. Core component of the BAF (SWI/SNF) complex. This ATP-dependent chromatin-remodeling complex plays important roles in cell proliferation and differentiation, in cellular antiviral activities and inhibition of tumor formation. Belongs to the neural progenitors-specific chromatin remodeling complex (npBAF complex) and the neuron-specific chromatin remodeling complex (nBAF complex) and may play a role in neural development (By similarity). Component of the multiprotein chromatin-remodeling complexes SWI/SNF. Component of neural progenitors-specific chromatin remodeling complex (npBAF complex) and the neuron-specific chromatin remodeling complex (nBAF complex) (By similarity). Component of the BAF (SWI/SNF) chromatin remodeling complex. Component of the SWI/SNF-B (PBAF) chromatin remodeling complex. Binds to double-stranded DNA. The N-terminal DNA-binding region is structurally similar to winged helix domains. Belongs to the SNF5 family.
