Trithorax group proteins, including COMPASS histone H3 lysine 4 methyltransferase complexes and SWI/SNF chromatin remodelling complexes, play crucial roles in gene regulation, development, and disease. Misregulation of these complexes through genetic abnormalities can lead to pathologies such as developmental disorders and malignancies.
The Trithorax group (TrxG) of proteins is a large family of epigenetic regulators that form multiprotein complexes to counteract repressive developmental gene expression programmes established by the Polycomb group of proteins and to promote and maintain an active state of gene expression. Recent studies are providing new insights into how two crucial families of the TrxG - the COMPASS family of histone H3 lysine 4 methyltransferases and the SWI/SNF family of chromatin remodelling complexes - regulate gene expression and developmental programmes, and how misregulation of their activities through genetic abnormalities leads to pathologies such as developmental disorders and malignancies. In this Review, Cenik and Shilatifard focus on two families of Trithorax group proteins: COMPASS histone H3 lysine 4 methyltransferase complexes and SWI/SNF chromatin remodelling complexes. They discuss the roles of these complexes in gene regulation, development and disease.
