PRC2 operates as two holocomplexes, PRC2.1 and PRC2.2, with EPOP serving as a PRC2.1-specific accessory subunit. Here the authors show that EPOP inhibits PRC2.1 by disrupting its dimeric structure, thereby weakening chromatin association to prevent excessive gene repression during early differentiation.
