Introduction

Full name: Euchromatic Histone Lysine Methyltransferase 2. EHMT2 is a ubiquitously expressed SET domain-containing protein that was originally characterized as a molecule encoded by a gene mapped in the class III region of the human major histocompatibility complex locus(1).EHMT2 contains a SET domain which can bind effectively to unmodified and H3K9me1 peptides,an ankyrin repeats which binds with strong preference to N-terminal H3 peptides containing mono- or dimethyl K9(2,3).EHMT2 is a histone methyltransferase that specifically mono- and dimethylate lysine 9 of histone H3(H3K9me1 and H3K9me2) in euchromatin,mediates monomethylation of lysine 56 of histone(H3K56me1) in G1 phase,weakly methylates lysine 27 of histone H3(2-5).

Function and Interaction

EHMT2 promotes interaction between histone H3 and PCNA and regulates DNA replication by mediates monomethylation of lysine 56 of histone H3(H3K56me1) in G1 phase(4).EHMT2 methylates DNA ligase 1 (LIG1) which recruits UHRF1 to DNA replication sites and is required for DNA methylation maintenance(6).EHMT2 regulates breast cancer growth by modulating iron homeostasis through the repression of ferroxidase hephaestin(7).EHMT2 has a dominant function in transcriptional repression of K(+) channels and in acute-to-chronic pain transition after nerve injury(8).EHMT2 promotes neuron differentiation and creates a positive feedback loop that reinforces cellular commitment to differentiation(9).

Disease Association

EHMT2 is associated with retinal neurodegenerative diseases such as borderline glaucoma(10).
