[[http://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> | [[http://www.uniprot.org/uniprot/SMYD2_HUMAN SMYD2_HUMAN]] Protein-lysine N-methyltransferase that methylates both histones and non-histone proteins.

| + | A lack of useful small molecule tools has precluded thorough interrogation of the biological function of SMYD2, a lysine methyltransferase with known tumor-suppressor substrates. Systematic exploration of the structure-activity relationships of a previously known benzoxazinone compound led to the synthesis of A-893, a potent and selective SMYD2 inhibitor (IC50: 2.8 nM). A cocrystal structure reveals the origin of enhanced potency, and effective suppression of p53K370 methylation is observed in a lung carcinoma (A549) cell line. | ||
