In the case of the H3K27 markmark, work by two independent laboratories has suggested that established H3K27 me3 attracts the EED component of the Polycomb Repressive Complex 2 (PRC2), and is required to stimulate the enzymatic activity necessary to maintain this mark on the daughter strands during incorporation of newly synthesized histones [ 79, 80].
