Involved in transcriptional activation and repression of select genes by chromatin remodeling (alteration of DNA-nucleosome topology). Component of SWI\/SNF chromatin remodeling complexes that carry out key enzymatic activities, changing chromatin structure by altering DNA-histone contacts within a nucleosome in an ATP-dependent manner. Binds DNA non-specifically. 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 postmitotic 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 postmitotic 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).\u003c\/p\u003e\u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e\u003cul\u003e\u003cli\u003eUse of recombinant standards to improve assay calibration and cross-study comparability.\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003eInvolved in transcriptional activation and repression of select genes by chromatin remodeling (alteration of DNA-nucleosome topology).
