CC   -!- FUNCTION: Involved in transcriptional activation and repression of
CC       select genes by chromatin remodeling (alteration of DNA-nucleosome
CC       topology). Component of SWI/SNF chromatin remodeling complexes that
CC       carry out key enzymatic activities, changing chromatin structure by
CC       altering DNA-histone contacts within a nucleosome in an ATP-dependent
CC       manner. Belongs to the neuron-specific chromatin remodeling complex
CC       (nBAF complex), as such plays a role in remodeling mononucleosomes in
CC       an ATP-dependent fashion, and is required for postmitotic neural
CC       development and dendritic outgrowth. During neural development a switch
CC       from a stem/progenitor to a postmitotic chromatin remodeling mechanism
CC       occurs as neurons exit the cell cycle and become committed to their
CC       adult state. The transition from proliferating neural stem/progenitor
CC       cells to postmitotic neurons requires a switch in subunit composition
CC       of the npBAF and nBAF complexes. As neural progenitors exit mitosis and
CC       differentiate into neurons, npBAF complexes which contain ACTL6A/BAF53A
CC       and PHF10/BAF45A, are exchanged for homologous alternative
CC       ACTL6B/BAF53B and DPF1/BAF45B or DPF3/BAF45C subunits in neuron-
CC       specific complexes (nBAF). The npBAF complex is essential for the self-
CC       renewal/proliferative capacity of the multipotent neural stem cells.
CC       The nBAF complex along with CREST plays a role regulating the activity
CC       of genes essential for dendrite growth. ACTL6B/BAF53B is not essential
CC       for assembly of the nBAF complex but is required for targeting the
CC       complex and CREST to the promoter of genes essential for dendritic
CC       growth. Essential for neuronal maturation and dendrite development (By
CC       similarity). {ECO:0000250|UniProtKB:O94805,
CC       ECO:0000250|UniProtKB:Q99MR0}.
CC   -!- SUBUNIT: Component of the multiprotein chromatin-remodeling complexes
CC       SWI/SNF: SWI/SNF-A (BAF), SWI/SNF-B (PBAF) and related complexes. The
CC       canonical complex contains a catalytic subunit (either
CC       SMARCA4/BRG1/BAF190A or SMARCA2/BRM/BAF190B) and at least SMARCE1,
CC       ACTL6A/BAF53, SMARCC1/BAF155, SMARCC2/BAF170, and SMARCB1/SNF5/BAF47.
CC       Other subunits specific to each of the complexes may also be present
CC       permitting several possible combinations developmentally and tissue
CC       specific (By similarity).Component of the BAF complex, which includes
CC       at least actin (ACTB), ARID1A/BAF250A, ARID1B/BAF250B, SMARCA2/BRM,
CC       SMARCA4/BRG1/BAF190A, ACTL6A/BAF53, ACTL6B/BAF53B, SMARCE1/BAF57,
CC       SMARCC1/BAF155, SMARCC2/BAF170, SMARCB1/SNF5/INI1, and one or more
CC       SMARCD1/BAF60A, SMARCD2/BAF60B, or SMARCD3/BAF60C (By similarity).
CC       Component of neuron-specific chromatin remodeling complex (nBAF
CC       complex) composed of at least, ARID1A/BAF250A or ARID1B/BAF250B,
CC       SMARCD1/BAF60A or SMARCD2/BAF60B or SMARCD3/BAF60C,
CC       SMARCA2/BRM/BAF190B, SMARCA4/BRG1/BAF190A, SMARCB1/BAF47,
CC       SMARCC1/BAF155, SMARCE1/BAF57, SMARCC2/BAF170, DPF1/BAF45B,
CC       DPF3/BAF45C, ACTL6B/BAF53B and actin (ACTB). Note that the nBAF complex
CC       is polymorphic in regard to the ATPase, SMARCA2 and SMARCA4 occupying
CC       mutually exclusive positions (By similarity). May be a component of the
CC       SWI/SNF-B (PBAF) chromatin remodeling complex, at least composed of
CC       SMARCA4/BRG1, SMARCB1/BAF47/SNF5, ACTL6A/BAF53A or ACTL6B/BAF53B,
CC       SMARCE1/BAF57, SMARCD1/BAF60A, SMARCD2/BAF60B, perhaps SMARCD3/BAF60C,
