This entry describes a group of enzymes that catalyse a single methylation of monomethylated lysine20 of histone H4 (H4K20m1, generated by EC, [histone H4]-lysine20 N-methyltransferase), forming the dimethylated form. This modification is broadly distributed across the genome and is likely important for general chromatin-mediated processes. The double-methylated form of lysine20 in histone H4 is the most abundant methylation state of this residue and is found on ~80% of all histone H4 molecules. Full activity of the enzyme requires that the lysine at position 9 of histone H3 is trimethylated.
