Anti-SMYD3 from rabbit

Histone-lysine N-methyltransferase SMYD3 (UniProt: Q9H7B4; also known as EC: 2.1.1.43, SET and MYND domain-containing protein 3, Zinc finger MYND domain-containing protein 1) is encoded by the SYMD3 (also known as ZMYND1, ZNFN3A1) gene (Gene ID: 64754) in human. SMYD3 is a member of the class V-like SAM-binding methyltransferase superfamily that specifically methylates 'Lys-4' of histone H3, inducing di- and tri-methylation, but not monomethylation. The SET domain of SMYD3 shows histone H3-lysine 4 (H3-K4)-specific methyltransferase activity, which is enhanced in the presence of HSP90A. SMYD3 also contains a MYND-type zinc finger domain (aa 49-87). It plays an important role in transcriptional activation as a member of an RNA polymerase II complex. SMYD3 is mainly cytoplasmic when cells are arrested at G0/G1, but accumulates in the nucleus at S phase and G2/M phases. It is expressed in skeletal muscles and testis and its overexpression has been shown in a majority of colorectal and hepatocellular carcinomas. Introduction of SMYD3 into NIH3T3 cells is reported to enhance cell growth and the knockdown of this gene with SiRNA induces growth suppression in cancer cells. (Ref.: Hamamoto, R et al. (2004). Nat.
