Function
Polycomb group (PcG) protein. Catalytic subunit of the PRC2/EED-EZH2 complex, which methylates 'Lys-9' and 'Lys-27' 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. -
Tissue specificity
Expressed in many tissues. Overexpressed in numerous tumor types including carcinomas of the breast, colon, larynx, lymphoma and testis. -
Sequence similarities
Belongs to the histone-lysine methyltransferase family. EZ subfamily.
Contains 1 SET domain. -
Developmental stage
Expression decreases during senescence of embryonic fibroblasts (HEFs). Expression peaks at the G1/S phase boundary. -
Post-translational
modificationsPhosphorylated by AKT1. Phosphorylation by AKT1 reduces methyltransferase activity. -
