General description

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.

Immunogen

GST-tagged recombinant protein corresponding to human BRG1.

The nucleolar 58-kDa microspherule protein (MSP58) protein is a candidate oncogene implicated in modulating cellular proliferation and malignant transformation. In this study, we show that knocking down MSP58 expression caused aneuploidy and led to apoptosis, whereas ectopic expression of MSP58

Mutations in the SMARCA4/BRG1 gene resulting in complete loss of its protein (BRG1) occur frequently in non-small cell lung cancer (NSCLC) cells. Currently, no single therapeutic agent has been identified as synthetically lethal with SMARCA4/BRG1 loss. We identify AURKA activity

Genome-wide studies have revealed that genes commonly have a high density of RNA polymerase II just downstream of the transcription start site. This has raised the possibility that genes are commonly regulated by transcriptional elongation, but this remains largely untested
