Anti-BRG1/BAF190A Antibody, clone 5B7

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.

~185 kDa observed. 184.6 kDa (human isoform 1), 181.3 kDa (human isoform 2), 181.6 kDa (human isoform 3), 181.7 kDa (human isoform 4), 181.3 kDa (human isoform 5), 181.4 kDa (mouse isoform 1), and 181.5 kDa (mouse isoform 2) calculated. Uncharacterized band(s) may appear in some lysates.

Epitope: N-terminal region.

GST-tagged recombinant internal fragment from the N-terminal region of human BRG1/BAF190A.
