Reaction: SUV39H1 (KMT1A), SUV39H2 (KTM1B), SETDB1 (KMT1E), SETDB2 (KMT1F) methylate dimethyl-lysine-10 of histone H3 (H3K9)
- in pathway: PKMTs methylate histone lysines
SUV39H1 (KMT1A) and SUV39H2 (KMT1B) and SETDB2 (KMT1F) selectively methylate lysine-10 of histone H3 (H3K9) (Rea et al. 2000, Rice et al. 2003, Falandry et al. 2010). Their predominant activity is conversion of dimethylated H3K9 to trimethylated H3K9 (Peters et al. 2003, Rice et al. 2003, Chin et al. 2006). SETDB1 (ESET, KMT1E) also predominantly methylates dimethylated H3K9 (Schultz et al. 2002), most effectively when complexed with ATF7IP (MCAF, hAM) (Wang et al. 2003).
