      Background InformationPolycomb group proteins are important for maintaining transcriptional silencing. One conserved PcG complex, PRC2, is composed of several proteins including the histone methyltransferase EZH2, the WD-repeat protein EED (Embryonic ectoderm development), and the Zn-finger protein Suz12. Transcriptional repression mediated by EED involves histone deacetylation, while the EZH2 methylates histone H3 on lysine 27. EED protein is present in four isoforms. These EED isoforms selectively associate with distinct EZH2-containing complexes, resulting in differential targeting of their associated methyltransferase activity. These complexes play a role in Hox gene silencing, X-inactivation, germline development, stem cell pluripotency and cancer metastasis.

      Entrez Gene Number
      Entrez Gene SummaryThis gene encodes a member of the Polycomb-group (PcG) family. PcG family members form multimeric protein complexes, which are involved in maintaining the transcriptional repressive state of genes over successive cell generations. This protein interacts with enhancer of zeste 2, the cytoplasmic tail of integrin beta7, immunodeficiency virus type 1 (HIV-1) MA protein, and histone deacetylase proteins. This protein mediates repression of gene activity through histone deacetylation, and may act as a specific regulator of integrin function. Two transcript variants encoding distinct isoforms have been identified for this gene.

      Purification MethodPurified
      UniProt Number
      UniProt SummaryFunction: Polycomb group (PcG) protein. Component of the PRC2/EED-EZH2 complex, which methylates Lys9 and Lys27 of histone H3, leading to transcriptional repression of the affected target gene. 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 and CDKN2A.
      Subunit structure: Interacts with MLL. Component of the PRC2/EED-EZH2 complex, which includes EED, EZH2, SUZ12, RBBP4 and RBBP7 and possibly AEBP2. The minimum components required for methyltransferase activity of the PRC2/EED-EZH2 complex are EED, EZH2 and SUZ12. The PRC2 complex may also interact with DNMT1, DNMT3A, DNMT3B and PHF1 via the EZH2 subunit and with SIRT1 via the SUZ12 subunit. Interacts with HDAC, HDAC2, histone H1 and YY1. May interact with the MA protein of HIV-1.
      Subcellular location: Nucleus. Note: Transiently colocalizes with XIST at inactive X chromosomes.
      Tissue specificity: Expressed in brain, colon, heart, kidney, liver, lung, muscle, ovary, peripheral blood leukocytes, pancreas, placenta, prostate, spleen, small intestine, testis, thymus and uterus. Appears to be overexpressed in breast and colon cancer.
      Molecular Weight~53 kDa observed. Uniprot describes three isoforms at 51 kDa (isoform 1), 53 kDa (isoform 2), and 46 kDa (isoform 3).
