[https://www.uniprot.org/uniprot/EHMT2_HUMAN EHMT2_HUMAN] Histone methyltransferase that specifically mono- and dimethylates 'Lys-9' of histone H3 (H3K9me1 and H3K9me2, respectively) in euchromatin. H3K9me represents a specific tag for epigenetic transcriptional repression by recruiting HP1 proteins to methylated histones. Also mediates monomethylation of 'Lys-56' of histone H3 (H3K56me1) in G1 phase, leading to promote interaction between histone H3 and PCNA and regulating DNA replication. Also weakly methylates 'Lys-27' of histone H3 (H3K27me). Also required for DNA methylation, the histone methyltransferase activity is not required for DNA methylation, suggesting that these 2 activities function independently. Probably targeted to histone H3 by different DNA-binding proteins like E2F6, MGA, MAX and/or DP1. May also methylate histone H1. In addition to the histone methyltransferase activity, also methylates non-histone proteins: mediates dimethylation of 'Lys-373' of p53/TP53. Also methylates CDYL, WIZ, ACIN1, DNMT1, HDAC1, ERCC6, KLF12 and itself.<ref>PMID:8457211</ref> <ref>PMID:11316813</ref> <ref>PMID:18438403</ref> <ref>PMID:20118233</ref> <ref>PMID:22387026</ref>

G9a is a histone lysine methyltransferase responsible for the methylation of histone H3 lysine 9. The discovery of A-366 arose from a unique diversity screening hit, which was optimized by incorporation of a propyl-pyrrolidine subunit to occupy the enzyme lysine channel. A-366 is a potent inhibitor of G9a (IC50: 3.3 nM) with greater than 1000-fold selectivity over 21 other methyltransferases.
