Distinct specificity and functions of PRC2 subcomplexes in human stem cells and cardiac differentiation
Much et al. reveal that the PRC2 subcomplexes PRC2.1 and PRC2.2 play distinct roles in the epigenetic repression of developmental genes in human stem cells. Interactions between the PRC2 core and its accessory proteins, DNA, and H3K36me3 dictate PRC2 activity and, ultimately, modulate cardiac differentiation and function.
