This entry represents the SET domain of SET and MYND domain-containing protein 1 (SMYD1). SMYD1 functions as a histone methyltransferase and regulates downstream gene transcription. It methylates histone H3 at 'Lys-4' (H3K4me), seems able to perform both mono-, di-, and trimethylation. SMYD1 plays a critical role in cardiomyocyte differentiation, cardiac morphogenesis and myofibril organisation, as well as in the regulation of endothelial cells (ECs) [, ]. It is expressed in vascular endothelial cells, it has been shown that knockdown of SMYD1 in endothelial cells impairs EC migration and tube formation [].The SMYD family consists of five members including SMYD1/2/3/4/5. They contain two highly conserved structural and functional domains, the SET and MYND domains. The SET domain is involved in lysine methylation, while the MYND domain is involved in protein-protein interaction. They are essential in several mammalian developmental pathways [, , , ].
