Histone Methylation Proteins

Histone methyltransferase (HMT) proteins are involved in the post-translational modification called histone methylation which causes transcription repression or activation, depending on the target sites. Protein arginine methyltransferases (PRMTs) catalyze the methylation of arginine residues and histone methyltransferases (HMTs) catalyze the methylation of lysine residues.
