EC 2.1.1.364     
Accepted name: [histone H3]-lysine4 N-methyltransferase
Reaction: S-adenosyl-L-methionine + a [histone H3]-L-lysine4 = S-adenosyl-L-homocysteine + a [histone H3]-N6-methyl-L-lysine4
Other name(s): KMT7 (gene name); SETD7 (gene name); SET7/9 (gene name); KIAA1717 (gene name); KMT2A (gene name); KMT2B (gene name); KMT2C (gene name); KMT2D (gene name); KMT2F (gene name); KMT2G (gene name); MLL1 (gene name); MLL2 (gene name); MLL3 (gene name); MLL4 (gene name); SETD1A (gene name)
Systematic name: S-adenosyl-L-methionine:[histone H3]-L-lysine4 N6-methyltransferase
Comments: This entry describes enzymes that catalyse a single methylation of the L-lysine4 residue of histone H3 (H3K4), generating a monomethylated form. This modifications influence the binding of chromatin-associated proteins and result in gene activation or suppression. Some enzymes that catalyse this reaction continue to generate a dimethyated form, these enzymes are classified under EC 2.1.1.370, [histone H3]-lysine4 N-dimethyltransferase. Other enzymes continue to catalyse a third methylation, those are classified under EC 2.1.1.354, [histone H3]-lysine4 N-trimethyltransferase.
