Background: Homo sapiens transmembrane protease, serine 2 (TMPRSS2) encodes a protein that belongs to the serine protease family. Serine proteases are known to be involved in many physiological and pathological processes. Some coronavirus viruses, including HCoV-229E, MERS-CoV, SARS-CoV, and SARS-CoV-2 virus, are found to use this protein for the entry into host cells via two independent mechanisms, proteolytic cleavage of ACE2 receptor which promotes viral uptake, and cleavage of coronavirus spike glycoproteins which activates the glycoprotein for host cell entry. SARS-CoV-2 uses the SARS-CoV receptor ACE2 for entry and the serine protease TMPRSS2 for S protein priming. A TMPRSS2 inhibitor approved for clinical use blocked entry and might constitute a treatment option. The viral S glycoprotein is cleaved by TMPRSS2, thus facilitating viral activation and representing one of the essential host factors for SARS-CoV-2 pathogenicity.
