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,
CC SMARCC1/BAF155, SMARCC2/BAF170, PBRM1/BAF180, ARID2/BAF200 and actin
CC (By similarity). {ECO:0000250|UniProtKB:O94805,
CC ECO:0000250|UniProtKB:Q99MR0}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250|UniProtKB:Q99MR0}.
CC -!- SIMILARITY: Belongs to the actin family. {ECO:0000305}.
