Biochem/physiol Actions

EED (ectoderm development protein) is required for proper EZH2 (enhancer of zeste homolog 2)-mediated methyltransferase activity. It also associates with PRC1 (polycomb repressive complex 1) and helps in bringing PRC1 to H3K27me3 (trimethylated lysine residue at position 27 in the protein histone H3) loci. EED also increases PRC1-mediated H2A (histone 2A) ubiquitin E3 ligase activity. Mutations in the EED gene are associated with overgrowth, intellectual disability and dysmorphic features. Change in the activity of EED is linked with the pathogenesis of myeloid disorders.

General description

EED (ectoderm development protein) is the part of the polycomb repressive complex 2 (PRC2) where it interacts with EZH2 (enhancer of zeste homolog 2). The protein has seven WD domains (β-transducin domains). The EED gene is mapped to human chromosome 11q14.
Human Embryonic Ectoderm Development (hEED), also known as WAIT-1, GenBank Accession No. NM_003797, amino acids 2-end with N-terminal FLAG-tag, MW = 51kDa, expressed in Sf9 cells via a baculovirus expression system.

Modulators and Proteins for Methylation

DNA methyltransferases are a family of enzymes that catalyze the transfer of a methyl group to DNA. There are five related DNA cytosine-5-methyltransferases (DNMTs) that transfer a methyl group from ...
