Several histone substrates have been identified for SMYD3; however, the data is controversial. In one study, SMYD3 has been shown to methylate histone H3 Lys4 (both di- and tri-methylation) and interact with RNA polymerase II to activate transcription (1). A second study has shown that SMYD3 preferentially methylates histone H4 Lys20 and interacts with nuclear receptor corepressor complex (NCOR) to repress transcription (2). A third study has shown that SMYD3 preferentially methylates histone H4 Lys5 (mono-, di-, and tri-methylation) (3). In addition, SMYD3 has been shown to methylate the endothelial growth factor receptor 1 (VEGFR1) on Lys831 and stimulate its kinase activity (4). Regardless of the preferred protein substrates, it is clear that SMYD3 functions as an oncogene. Research studies have shown SMYD3 is highly over-expressed in liver, breast, and rectal carcinomas. Over-expression of SMYD3 in multiple cell lines enhances proliferation, adhesion, and migration, while reduced expression results in significant suppression of cell growth (1,5-10). In addition, multiple cancer cell lines express both full length SMYD3 and a cleaved form of SMYD3 lacking the N-terminal 34 amino acids, and the cleaved form shows increased methyltransferase activity toward histone H3 (11).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nbA74P14.1; bA74P14.1 (novel protein); FLJ21080; Histone-lysine N-methyltransferase SMYD3; KMT3E; MGC104324; SET and MYND domain containing 3; SET and MYND domain-containing protein 3; SMYD3; Zinc finger MYND domain-containing protein 1; zinc finger protein, subfamily 3A (MYND domain containing), 1; zinc finger, MYND domain containing 1; ZMYND1; ZNFN3A1\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H Mk\nSENSITIVITY: Endogenous\nMW (kDa): 42\nSource\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46797582205097,"sku":"12859T","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-12859t","provider":"Iright","version":"1.0","type":"link"}
