What is the function of this protein?
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.  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).  Binds DNA non-specifically (PubMed:14982958, PubMed:15170388).
