The modulation of chromatin structure is an essential component in the regulation of transcriptional activation and repression. Modifications can be made by at least two evolutionarily conserved strategies, through the disruption of histone-DNA contacts by ATP-dependent chromatin remodelers, or by histone tail modifications including methylation and acetylation. One of the four classes of ATP-dependent histone remodelers is the SWI/SNF complex, the central catalytic subunit of which is Brg1 or the highly related protein hBRM (1). This SWI/SNF complex contains varying subunits but its association with either Brg1 or hBRM remains constant (1). SWI/SNF complexes have been shown to regulate gene activation, cell growth, the cell cycle and differentiation (1). Brg1/hBRM have been shown to regulate transcription through enhancing transcriptional activation of glucocorticoid receptors (2). Although usually associated with transcriptional activation, Brg1/hBRM have also been found in complexes associated with transcriptional repression including with HDACs, Rb and Tif1b (3-5). Brg1/hBRM plays a vital role in the regulation of gene transcription during early mammalian embryogenesis. In addition, Brg1/hBRM also play a role as a tumor suppressors and Brg1 is mutated in several tumor cell lines (6-8).

NCBI Description

The protein encoded by this gene is a member of the SWI/SNF family of proteins and is similar to the brahma protein of Drosophila. Members of this family have helicase and ATPase activities and are thought to regulate transcription of certain genes by altering the chromatin structure around those genes. The encoded protein is part of the large ATP-dependent chromatin remodeling complex SNF/SWI, which is required for transcriptional activation of genes normally repressed by chromatin. In addition, this protein can bind BRCA1, as well as regulate the expression of the tumorigenic protein CD44. Mutations in this gene cause rhabdoid tumor predisposition syndrome type 2. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, May 2012]

Uniprot Description

SMARCA4: a member of the SWI/SNF nucleosome remodeling complex with ATP-dependent DNA helicase activity. SWI/SNF complexes are required for mammalian development and are mutated in ~20% of all human primary tumors. Mutated in 35% (13/37) of NSCLC and 5% (1/19) of SCLC human lung cancer cell lines . A component of the CREST-BRG1 complex, a multiprotein complex that regulates promoter activation by orchestrating a calcium-dependent release of a repressor complex and a recruitment of an activator complex. Belongs to the neural progenitor-specific chromatin remodeling complex (npBAF complex) and the neuron-specific chromatin remodeling complex (nBAF complex). Component of the BAF53 complex which acetylates histone H4 and H2A within nucleosomes. Transcriptional coactivator of nuclear hormone receptors. Acts as a corepressor of ZEB1 to regulate E-cadherin transcription, and is required for induction of epithelial-mesenchymal transition (EMT) by ZEB1. Can bind BRCA1, as well as regulate the expression of the tumorigenic protein CD44. SMARCA4, in consort with ZEB1, represses the transcription of E-cadherin and promotes the epithelial-to-mesenchymal transisition (EMT). SMARCA4 is required for stem cell maintenance in the mouse intestinal epithelium. Its loss inhibits aberrant Wnt-signalling and prevents tumorigenesis in the mouse small intestine. SMARCA4 mutations are the cause of a familial cancer syndrome predisposing to renal or extrarenal malignant rhabdoid tumors and to a variety of tumors of the central nervous system, including choroid plexus carcinoma, medulloblastoma, and central primitive neuroectodermal tumors. Rhabdoid tumors are the most aggressive and lethal malignancies occurring in early childhood. Belongs to the SNF2/RAD54 helicase family. The human protein includes 5 isoforms produced by alternative splicing.
