PubMed Abstract:
Zhang et al suggested that in the crystal structure of a polycomb repressive complex 2 from Chaetomium thermophilum (ctPRC2), a flexible linker region, but not the H3K27M cancer mutant peptide, better fits the electron density. Based on our new data, we agree with this alternative interpretation and provide the crystal structure of ctPRC2 bound to a bona fide H3K27M sequence.
