Macro domains as metabolite sensors on chromatin
Cellular and molecular life sciences : CMLS(2013)
摘要
How metabolism and epigenetics are molecularly linked and regulate each other is poorly understood. In this review, we will discuss the role of direct metabolite-binding to chromatin components and modifiers as a possible regulatory mechanism. We will focus on globular macro domains, which are evolutionarily highly conserved protein folds that can recognize NAD + -derived metabolites. Macro domains are found in histone variants, histone modifiers, and a chromatin remodeler among other proteins. Here we summarize the macro domain-containing chromatin proteins and the enzymes that generate relevant metabolites. Focusing on the histone variant macroH2A, we further discuss possible implications of metabolite binding for chromatin function.
