Protein: ATP-dependent helicase brm (EC 3.6.4.12) (Homeotic gene regulator) (Protein brahma) (P25439)
Organism: Drosophila melanogaster (Fruit fly)
Function: Transcriptional regulator. Acts as a coactivator, assisting one or more dedicated transcriptional activators of ANTC and BXC homeotic gene clusters. Can counteract the repressive effect of Polycomb protein. ATPase subunit of the Brahma complex, a multiprotein complex which is the equivalent of the yeast SWI/SNF complex and acts by remodeling the chromatin by catalyzing an ATP-dependent alteration in the structure of nucleosomal DNA. This complex can both serve as a transcriptional coactivator or corepressor, depending on the context. In type II neuroblast lineage, as part of the Brm remodeling complex, suppresses the formation of ectopic neuroblasts probably through interaction with erm and HDAC3.
Subcellular location: Nucleus.
