SET and MYND domain containing 2 is a protein that in humans is encoded by the SMYD2 gene.^[5]

Function

SMYD2 belongs to the SET and MYND domain-containing (SMYD) family of protein lysine methyltransferases, which methylate lysine residues in both histone and non-histone substrates.^[6]

This enzyme methylates histone H3 at lysine 4 and lysine 36. In addition, it methylates a broad range of non-histone proteins, including the tumor suppressors p53 and Rb, the molecular chaperone Hsp90, estrogen receptor α, and PARP1. This methylation affects the stability and function of target proteins and hence is able to regulate a signicant number of cellular processes including apoptosis and cell cycle progression.^[7]

Clinical significance

Because SMYD2 methylation of p53 and Rb interferes with their tumor suppressor function, over expression of SMYD2 has been associated with worse outcomes in numerous types of cancer, including esophageal squamous cell carcinoma, breast, gastric, hepatocellular, and pancreatic ductal adenocarcinoma.^[5] These cancer associations have lead to the development of small-molecule inhibitors of SMYD2 that suppress the proliferation of cancer cell lines.^[5]
