Sister-of-Mammalian Grainyhead (SOM) is a member of the Grainyhead family of transcription factors. In humans, 3 isoforms are derived from differential first exon usage and alternative splicing and differ only in their N terminal domain. SOM2, the only variant also present in mouse, induces endothelial cell migration and protects against apoptosis. The functions of the human specific isoforms SOM1 and SOM3 have not yet been investigated. Therefore we wanted to elucidate their functions in endothelial cells.
