CC   -!- FUNCTION: Involved in chromatin-remodeling. Core component of the BAF
CC       (SWI/SNF) complex. This ATP-dependent chromatin-remodeling complex
CC       plays important roles in cell proliferation and differentiation, in
CC       cellular antiviral activities and inhibition of tumor formation.
CC       Belongs to the neural progenitors-specific chromatin remodeling complex
CC       (npBAF complex) and the neuron-specific chromatin remodeling complex
CC       (nBAF complex) and may play a role in neural development (By
CC       similarity). {ECO:0000250|UniProtKB:Q12824}.
CC   -!- SUBUNIT: Component of the multiprotein chromatin-remodeling complexes
CC       SWI/SNF. Component of neural progenitors-specific chromatin remodeling
CC       complex (npBAF complex) and the neuron-specific chromatin remodeling
CC       complex (nBAF complex) (By similarity). Component of the BAF (SWI/SNF)
CC       chromatin remodeling complex. Component of the SWI/SNF-B (PBAF)
CC       chromatin remodeling complex. Binds to double-stranded DNA (By
CC       similarity). {ECO:0000250|UniProtKB:Q12824,
CC       ECO:0000250|UniProtKB:Q9Z0H3}.
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250}.
CC   -!- DOMAIN: The N-terminal DNA-binding region is structurally similar to
CC       winged helix domains. {ECO:0000250|UniProtKB:Q12824}.
CC   -!- SIMILARITY: Belongs to the SNF5 family. {ECO:0000305}.
