May have an important role in developing neurons by participating in regulation of cell survival, possibly as a neurospecific transcription factor. Belongs to the neuron-specific chromatin remodeling complex (nBAF complex) and plays a role in neural development. Component of neuron-specific chromatin remodeling complex (nBAF complex), a subfamily of ATP-dependent SWI/SNF chromatin remodeling complexes. Belongs to the requiem/DPF family.
