FunctionPlays a role in ATP dependent nucleosome remodeling by SMARCA4 containing complexes. Stimulates nuclear receptor mediated transcription. Belongs to the neural progenitors-specific chromatin remodeling complex (npBAF complex) and the neuron- specific chromatin remodeling complex (nBAF complex). During neural development a switch from a stem/progenitor to a post- mitotic chromatin remodeling mechanism occurs as neurons exit the cell cycle and become committed to their adult state. The transition from proliferating neural stem/progenitor cells to post-mitotic neurons requires a switch in subunit composition of the npBAF and nBAF complexes. As neural progenitors exit mitosis and differentiate into neurons, npBAF complexes which contain ACTL6A/BAF53A and PHF10/BAF45A, are exchanged for homologous alternative ACTL6B/BAF53B and DPF1/BAF45B or DPF3/BAF45C subunits in neuron-specific complexes (nBAF). The npBAF complex is essential for the self-renewal/proliferative capacity of the multipotent neural stem cells. The nBAF complex along with CREST plays a role regulating the activity of genes essential for dendrite growth (By similarity). {ECO:0000250}.

SubunitComponent of the BAF complex, which includes at least actin (ACTB), ARID1A, ARID1B/BAF250, SMARCA2, SMARCA4/BRG1/BAF190A, ACTL6A/BAF53, ACTL6B/BAF53B, SMARCE1/BAF57, SMARCC1/BAF155, SMARCC2/BAF170, SMARCB1/SNF5/INI1, and one or more of SMARCD1/BAF60A, SMARCD2/BAF60B, or SMARCD3/BAF60C. In muscle cells, the BAF complex also contains DPF3. Interacts with SMARCA4/BRG1/BAF190A, the catalytic subunit of the SWI/SNF related nucleosome-remodeling complexes BRG1(I) and BRG1(II). The precise distribution of the related SMARCD1, SMARCD2 and SMARCD3 proteins among these and other SWI/SNF nucleosome-remodeling complexes is not fully known. Also interacts with several nuclear receptors including PPARG/NR1C3, RXRA/NR1F1, ESR1, NR5A1, NR5A2/LRH1 and other transcriptional activators including the HLH protein SREBF1/SREBP1 and the homeobox protein PBX1. May allow recruitment of Swi/SNF containing complexes specifically to promoters where these factors are located.
