Transcription activator BRG1 (UniProt P51532; also known as ATP-dependent helicase SMARCA4, BAF190A, BRG1-associated factor 190A, hSNF2b, Mitotic growth and transcription activator, Protein brahma homolog 1, Protein BRG-1, SNF2-beta, SWI/SNF-related matrix-associated actin-dependent regulator of chromatin subfamily A member 4) is encoded by the SMARCA4 (also known as BAF190A, BRG1, MRD16, RTPS2, SNF2B, SNF2L4) gene (Gene ID 6597) in human. The SWI/SNF-like BRG1/BRM-associated factor (BAF) chromatin-remodeling complexes drive conformational changes of nucleosomes in an ATP-dependent manner and play important roles in cell-cycle progression, DNA repair, and development. The SWI/SNF complexes contain 10-12 interchangeable subunits, with either BRG1/SMARCA4 or BRM/SMARCA2 as the ATPase subunit. Brg1 is also shown to maintain Polycomb-mediated repression of non-mesodermal developmental regulators. Brg1-knockout leads to disruption of murine ESC cardiomyocyte differentiation and dysregulation of lineage-specific gene expression during mesoderm induction.
