Description
General description
BAF190B (BRG1-associated factor 190B), also known as protein brahma homolog (Brm), and SNF2-alpha, functions as a transcriptional coactivator. This protein contains a helicase domain and is a member of the SWI/SNF family of proteins and is part of the SWI-SNF chromatin remodeling complex. The SWI-SNF complex is involved in the activation of transcription via the remodeling of nucleosome structure in an ATP-dependent manner. This large complex contains multiple proteins. BAF190 (Brm) and Brg-1 (SNF2-beta) are the ATPase subunits of the mammalian SWI-SNF complex. Brm, Brg-1, Ini1 (integrase interactor 1, or SNF5), BAF155 (SRG3) and BAF170 are thought to comprise the functional core of the SWI-SNF complex. Other complex subunits are thought to play regulatory roles. hSNF2L and hSNF2H both appear to be homologs of Drosophila ISWI, a Brm related ATPase that is present in chromatin remodeling complexes other than SWI/SNF, including the NURF (nucleosome remodeling factor).
~140-180 kDa observed. Uncharacterized lower molecular weight bands have been reported in some lysates and may represent splice variants and/or degradation products. See Batsché E, Yaniv M, Muchardt C. Nat Struct Mol Biol. 2006 Jan;13(1):22-29.
