USAGE For Research Use Only! Not For Use in Humans.


The transmembrane serine protease 2 (TMPRSS2) plays an important role in the infection mechanism of human coronaviruses such as SARS-CoV-2. Cell entry of SARS-CoV-2 depends on the binding of the viral spike (S) glycoprotein to the ACE2 receptor and S protein priming by TMPRSS2. The protease domain of TMPRSS2 is also theorized to be cleaved and secreted extracellularly after autocleavage. Additionally, TMPRSS2 is shown to be upregulated by androgen in prostate cancer cells and downregulated in androgen-independent prostate cancer.
