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 SWI/SNF, which is required for transcriptional activation of genes normally repressed b… WebNov 26, 2024 · These findings suggest that a subunit switching event from BRG1 to BRM, normally associated with myogenesis 29, may be impaired in the maintenance of RMS cell dedifferentiation and proliferative...

WebDec 23, 2024 · Small cell carcinoma of the ovary, hypercalcemic type (SCCOHT) is a rare and aggressive form of ovarian cancer. SCCOHT tumors have inactivating mutations in SMARCA4 (BRG1), one of the two mutually exclusive ATPases of the SWI/SNF chromatin remodeling complex. To address the role that BRG1 loss plays in SCCOHT … WebDec 2, 2024 · In this study, we show that the catalytic subunit of the mammalian SWI/SNF (BAF) chromatin remodeling complex, BRG1 (encoded by SMARCA4 ), maintains glioma stem cells in an OPC-like state and describe the functional impact of SMARCA4 loss in H3K27M-glioma cells. hypodense hepatic parenchyma
