[https://www.uniprot.org/uniprot/SUZ12_CHATD SUZ12_CHATD] Component of the of the Polycomb Repressive Complex 2 (PRC2), a histone H3 lysine methyltransferase responsible for generating mono-, di-, and tri-methylation on Lys27 (H3K27me1, H3K27me2 and H3K27me3) (PubMed:26472914, PubMed:28008037). The tri-methylated form is known to be critical in gene repression, and its proper placement is essential in defining repression patterns during development (PubMed:26472914, PubMed:28008037). SUZ12 is not a catalytic subunit but is required for the complex regulation of histone H3 lysine methylation by EZH2 (PubMed:26472914).<ref>PMID:26472914</ref> <ref>PMID:28008037</ref> | |||

== Publication Abstract from PubMed == | |||
Jiao and Liu (Research Articles, 16 October 2015, aac4383) reported the crystal structure of the protein complex polycomb repressive complex 2 from Chaetomium thermophilum This landmark structure has brought invaluable insights into the activation mechanism of this essential methyltransferase. However, the analysis of the x-ray data discussed below suggests that the description of oncogenic H3K27M peptide binding to the active site is incorrect. | |||
