SMARCA1: Proteins and Enzymes

The SWI/SNF-related, matrix-associated, actin-dependent regulators of chromatin (SMARC), also called BRG1-associated factors (BAFs), have been identified as components of the human SWI/SNF-like chromatin-remodeling protein complexes. Member of this family have helicase and ATPase activities that alter chromatin structure to facilitate gene transcription. SMARCA1/SNF2L is a component of the human NURF (nucleosome remodeling factor) involved in the regulation of genes involved in neuronal development. SMARCA1/SNF2L is also a component of the heterodimeric complex CERF [CECR2(cat eye syndrome chromosome region, candidate 2)-containing remodeling factor]. Alternate names for SMARCA1/SNF2L include SWI/SNF-related matrix-associated actin-dependent regulator of chromatin a1, SNF2, SNF2L, SNF2L1, SNF2LB, sucrose nonfermenting 2-like protein 1, NURF140, and ISWI.
