ID:EED_HUMAN DESCRIPTION: RecName: Full=Polycomb protein EED; Short=hEED; AltName: Full=WD protein associating with integrin cytoplasmic tails 1; Short=WAIT-1; FUNCTION: Polycomb group (PcG) protein. Component 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. Also recognizes 'Lys-26' trimethylated histone H1 with the effect of inhibiting PRC2 complex methyltransferase activity on nucleosomal histone H3 'Lys-27', whereas H3 'Lys-27' recognition has the opposite effect, enabling the propagation of this repressive mark. 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: Interacts with MLL (By similarity). 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. Component of the PRC2/EED-EZH1 complex, which includes EED, EZH1, SUZ12, RBBP4 and AEBP2. 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 ITGA4, ITGAE and ITGB7. May interact with the MA protein of HIV-1. INTERACTION: Self; NbExp=2; IntAct=EBI-923794, EBI-923794; P26358:DNMT1; NbExp=3; IntAct=EBI-923794, EBI-719459; Q9Y6K1:DNMT3A; NbExp=2; IntAct=EBI-923794, EBI-923653; Q9UBC3:DNMT3B; NbExp=4; IntAct=EBI-923794, EBI-80125; Q15156:PML-RAR; NbExp=2; IntAct=EBI-923794, EBI-867256; SUBCELLULAR LOCATION: Nucleus. Chromosome. 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. DEVELOPMENTAL STAGE: Expression peaks at the G1/S phase boundary. INDUCTION: Expression is induced by E2F1, E2F2 and E2F3. DOMAIN: The WD repeat domain mediates recognition of trimethylated histone peptides at the consensus sequence Ala-Arg-Lys-Ser. This is achieved through an aromatic cage encircling the methyllysine, and involving Phe-97, Tyr-148 and Tyr-365. PTM: Methylated. Binding to histone H1 'Lys-26' promotes mono-, di-, and trimethylation of internal lysines. SIMILARITY: Belongs to the WD repeat ESC family. SIMILARITY: Contains 7 WD repeats. CAUTION: Two variants of the PRC2 complex have been described, termed PRC3 and PRC4. Each of the three complexes may include a different complement of EED isoforms, although the precise sequences of the isoforms in each complex have not been determined. The PRC2 and PRC4 complexes may also methylate 'Lys- 26' of histone H1 in addition to 'Lys-27' of histone H3 (PubMed:15099518 and PubMed:15684044), although other studies have demonstrated no methylation of 'Lys-26' of histone H1 by PRC2 (PubMed:16431907). SEQUENCE CAUTION: Sequence=AAC23685.1; Type=Erroneous initiation; Sequence=AAC68675.1; Type=Erroneous initiation;
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
