== Function ==
[https://www.uniprot.org/uniprot/SMYD2_HUMAN SMYD2_HUMAN] Protein-lysine N-methyltransferase that methylates both histones and non-histone proteins. Specifically methylates histone H3 'Lys-4' (H3K4me) and dimethylates histone H3 'Lys-36' (H3K36me2). Has also methyltransferase activity toward non-histone proteins such as p53/TP53 and RB1. Monomethylates 'Lys-370' of p53/TP53, leading to decreased DNA-binding activity and subsequent transcriptional regulation activity of p53/TP53. Monomethylates 'Lys-860' of RB1/RB.<ref>PMID:17108971</ref> <ref>PMID:17805299</ref> <ref>PMID:18065756</ref> <ref>PMID:20870719</ref>
