[[https://www.uniprot.org/uniprot/EED_HUMAN EED_HUMAN]] 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.<ref>PMID:9584199</ref> <ref>PMID:10581039</ref> <ref>PMID:14532106</ref> <ref>PMID:15385962</ref> <ref>PMID:15231737</ref> <ref>PMID:15225548</ref> <ref>PMID:16357870</ref> <ref>PMID:18285464</ref> <ref>PMID:20974918</ref>

== Publication Abstract from PubMed ==
Embryonic ectoderm development (EED) is a promising therapeutic target for human cancers and other diseases. We report herein the discovery of exceptionally potent and efficacious EED inhibitors. By conformational restriction of a previously reported EED inhibitor, we obtained a potent lead compound. Further optimization of the lead yielded exceptionally potent EED inhibitors. The best compound EEDi-5273 binds to EED with an IC50 value of 0.2 nM and inhibits the KARPAS422 cell growth with an IC50 value of 1.2 nM. It demonstrates an excellent PK and ADME profile, and its oral administration leads to complete and persistent tumor regression in the KARPAS422 xenograft model with no signs of toxicity. Co-crystal structures of two potent EED inhibitors with EED provide a solid structural basis for their high-affinity binding. EEDi-5273 is a promising EED inhibitor for further advanced preclinical development for the treatment of human cancer and other human diseases.
