ETV5: Proteins and Enzymes

ETS translocation variant 5 (ETV5), also known as ERM, is an approximately 70 kDa member of the ETS transcription factor family. The expression of ETV5 in Sertoli, granulosa, and cumulus cells is important for the ability of these cells to support spermatogonia stem cell and oocyte development. ETV5 is upregulated at the invasive front of various carcinomas, and it plays a role in tumor cell invasiveness. It is a target of chromosomal translocation in prostate cancer and forms a fusion protein with TMPRSS2. It is also required for branching morphogenesis during early kidney development. ETV5 contains a single Ets DNA-binding domain (aa 367-452).
