FunctionFunction

Histone methyltransferase (HMT) are histone-lysine N-methyltransferase (KHMT) and histone-arginine N-methyltransferase (RHMT) which catalyzes the transfer of methyl groups to lysine and arginine residues of histones[1]. HMT use S-adenosyl methionine (SAM) or S-adenosyl homocysteine (SAH) as the methyl donor. KHMT can be SET domain-containing or non-SET domain-containing. The SET domain contains the catalytic core of KHMT and targets the lysine tail region of KHMT. CxxC domain is a zinc finger domain.

RelevanceRelevance

Inhibitors of the histone-lysine N-methyltransferase SMYD2 which represses the tumor-suppressing activities of p53 are studied as cancer therapy drugs.

DiseaseDisease

Aberrant HMT plays a role in cancer, intellectual disability syndromes and regulation of tissue aging[2].
