Comments:

The enzyme, characterized from yeast, catalyses the successive methylation of lysine36 of histone H3 (H3K36), forming the trimethylated form. These modifications influence the binding of chromatin-associated proteins. The enzyme couples the methylation reactions with transcriptional elongation through an interaction with the large subunit of RNA polymerase II. In mammals this activity is catalysed by two different enzymes, EC 2.1.1.357, [histone H3]-lysine36 N-dimethyltransferase and EC 2.1.1.358, [histone H3]-dimethyl-L-lysine36 N-methyltransferase.
