May be a transcriptional activator. May be involved in chromatin remodeling. Plays a role in the regulation of cell morphology and cytoskeletal organization. Required in the control of cell shape. Interacts with SMARCA4. Ubiquitously expressed. Broadly expressed during development. Expression begins to increase at 7.5 dpc, peaks at 10.5-11.5 dpc, and decreases from 14.5 dpc. Weakly expressed at late embryonic stages.
