Energy-transducing component of NURF (nucleosome- remodeling factor) and CERF (CECR2-containing-remodeling factor) complexes. Both complexes facilitate the perturbation of chromatin structure in an ATP-dependent manner. Potentiates neurite outgrowth. May be involved in brain development by regulating En-1 and En-2 expression. May be involved in the development of luteal cells. Part of the nucleosome-remodeling factor (NURF) complex which consists of SMARCA1; BPTF; RBBP4 and RBBP7. Part of the CECR2-containing-remodeling factor (CERF) complex which contains CECR2 and SMARCA1. Interacts with PRLR. Belongs to the SNF2/RAD54 helicase family. ISWI subfamily. 2 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
