General description

Brahma-related gene 1 (Brg1), also known as SWI/SNF related, matrix associated, actin dependent regulator of chromatin, subfamily a, member 4 (SMARCA4), is encoded by the gene mapped to human chromosome 19p13.2. The encoded protein is characterized with a conserved catalytic ATPase domain, a conserved C-terminal bromodomain, AT-hook motif and the less characterized N-terminal region housing QLQ, helicase-SANT-associated (HSA) and BRM and KIS (BRK) domains.

Biochem/physiol Actions

Brahma-related gene 1 (Brg1), acts as a catalytic subunit for various mammalian SWItch/Sucrose non-fermentable (SWI/SNF) complexes, where it helps in transcription regulation through the nucleosome remodelling. Additionally, it plays an essential role in differentiation of myeloid to granulocytes. Mutation in the gene is associated with the development of Coffin-Siris syndrome and rhabdoid tumor predisposition syndrome. Loss of Brg1 expression is used as a potential diagnostic marker for ovarian small cell carcinoma of the hypercalcemic type (SCCOHT).
