Involved in transcription activity regulation by chromatin remodeling in the context of the neural progenitors-specific chromatin remodeling complex (npBAF complex). May play a role in the proliferation of neural progenitors (By similarity). Component of neural progenitors-specific chromatin remodeling complex (npBAF complex), a subfamily of ATP-dependent SWI/SNF chromatin remodeling complexes. Belongs to the SAYP family. It is uncertain whether Met-1 or Met-83 is the initiator. Truncated N-terminus. Truncated N-terminus.
