Function

SMYD3 is a histone methyltransferase that plays a role in transcriptional regulation as a member of an RNA polymerase complex.[5]

Model organisms have been used in the study of SMYD3 function. A conditional knockout mouse line, called Smyd3^{tm2a(KOMP)Wtsi}[10][11] was generated as part of the International Knockout Mouse Consortium program — a high-throughput mutagenesis project to generate and distribute animal models of disease to interested scientists — at the Wellcome Trust Sanger Institute.[12][13][14]

Male and female animals underwent a standardized phenotypic screen to determine the effects of deletion.[8][15] Twenty three tests were carried out on homozygous mutant adult mice, however no significant abnormalities were observed.[8]

Interactions

SMYD3 has been shown to interact with Heat shock protein 90kDa alpha (cytosolic), member A1[16] and POLR2A.[16]

SMYD3 trimethylates a lysine residue on MAP3K2, which causes crosstalk into the MAP kinase signaling pathway in Ras-driven cancers.[17]
