Glioma tumor suppressor candidate region gene 1 (GLTSCR1) and its paralog GLTSCR1-like form SWI/SNF chromatin remodeling subcomplexes.

ABSTRACT: The mammalian SWI/SNF chromatin remodeling complex is a heterogeneous collection of related protein complexes required for gene regulation and genome integrity. It contains a central ATPase (BRM or BRG1) and various combinations of 10-14 accessory subunits (BAFs for BRM/BRG1 Associated Factors). Two distinct complexes differing in size, BAF and the slightly larger polybromo-BAF (PBAF), share many of the same core subunits but are differentiated primarily by having either AT-rich interaction domain 1A/B (ARID1A/B in BAF) or ARID2 (in PBAF). Using density gradient centrifugation and immunoprecipitation, we have identified and characterized a third and smaller SWI/SNF subcomplex. We termed this complex GBAF because it incorporates two mutually exclusive paralogs, G
