== Function ==
== Function ==
[[http://www.uniprot.org/uniprot/EZH2_HUMAN EZH2_HUMAN]] Polycomb group (PcG) protein. Catalytic subunit of the PRC2/EED-EZH2 complex, which methylates 'Lys-9' (H3K9me) and 'Lys-27' (H3K27me) of histone H3, leading to transcriptional repression of the affected target gene. Able to mono-, di- and trimethylate 'Lys-27' of histone H3 to form H3K27me1, H3K27me2 and H3K27me3, respectively. Compared to EZH2-containing complexes, it is more abundant in embryonic stem cells and plays a major role in forming H3K27me3, which is required for embryonic stem cell identity and proper differentiation. The PRC2/EED-EZH2 complex may also serve as a recruiting platform for DNA methyltransferases, thereby linking two epigenetic repression systems. Genes repressed by the PRC2/EED-EZH2 complex include HOXC8, HOXA9, MYT1, CDKN2A and retinoic acid target genes. EZH2 can also methylate non-histone proteins such as the transcription factor GATA4 and the nuclear receptor RORA.<ref>PMID:14532106</ref> <ref>PMID:15385962</ref> <ref>PMID:15231737</ref> <ref>PMID:15225548</ref> <ref>PMID:16179254</ref> <ref>PMID:16618801</ref> <ref>PMID:16357870</ref> <ref>PMID:16936726</ref> <ref>PMID:17210787</ref> <ref>PMID:17344414</ref> <ref>PMID:19026781</ref> <ref>PMID:18285464</ref> <ref>PMID:20935635</ref> <ref>PMID:23063525</ref>
