Polycomb repressive complex 2 (PRC2) and its histone H3 lysine-27 methylation activity are crucial for multicellular development by virtue of their role in maintaining transcriptional repression patterns. The recruitment and enzymatic activity of PRC2 are controlled by a series of intricate mechanisms whose molecular details have been emerging at a rapid pace. Recent studies have uncovered intriguing modes of PRC2 regulation by facultative PRC2 subunits, PRC1, and specific features of the chromatin environment. Together, these findings have produced a rich and fast-evolving picture of the biochemical signals that govern PRC2 function, with many exciting questions still remaining.
