This 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. [provided by RefSeq, Jul 2008]

EED: a member of the superfamily of Polycomb group (PcG) methyltransferase proteins with WD-40 repeats. PcG complexes mediate chromatin modifications that contribute to transcriptional silencing during development and carcinogenesis. A part of the Polycomb-repressive complex 2 (PRC2) along with EZH2, SUZ12, RBBP4 and RBBP7 and possibly AEBP2. Interacts with HDAC, HDAC2, histone H1 and YY1. PRC2 trimethylates histone H3 on K9 and K27, transcriptionally repressing target gene including HOXC8, HOXA9, MYT1 and CDKN2A. Appears to be overexpressed in breast and colon cancers. Inhibitors of PRC2-mediated gene repression are being investigated as a cancer therapy. EED and EZH2 are also implicated in the silencing of the inactive X chromosome. Three human isoforms produced by alternative splicing or initiation have been described, and additional isoforms may be produced by alternative initiation.
