Background: TMPRSS2

TMPRSS2, also called Epitheliasin in mice, is a 492 amino acid type II transmembrane serine protease located on human chromosome 21q22.3 that encodes at least 2 isoforms. This glycosylated serine protease (theoretical molecular weight 70kDa) is regulated by androgens and expressed on the plasma membrane of human bronchial epithelial cells, nasal goblet cells, small intestine epithelia, gastrointestinal tract, the stomach, kidneys and pancreas, with the greatest abundance found in the prostate gland. While the physiological function of TMPRSS2 remains unknown, the serine protease domain undergoes autocleavage and the 32 kDa domain is secreted enabling its interaction with the extracellular matrix. Fusions between TMPRSS2 and the ETS transcription factor genes ERG, ETV1, and ETV4 have been reported in prostate cancer with the TMPRSS2 ERG gene fusion resulting in ERG overexpression in 40-80% of these cases and often producing a more aggressive phenotype. Androgen signaling is disrupted in prostate cancers with the TMPRSS2 ERG fusion which contributes to the switch from androgen dependent to androgen independent prostate cancer (1,2).

TMPRSS2 has also been shown to play a critical role in the process of viral entry for coronaviruses and influenza viruses thru proteolytic activation of key viral glycoproteins. One pathway for SARS-CoV-2 infection, which causes the COVID-19 disease, involves binding of the SARS-CoV-2 Spike 'S' glycoprotein to the human ACE2 receptor and cleavage of S by TMPRSS2 at the cell surface to facilitate viral entry. TMPRSS2 mediates viral entry in a similar mechanism for other coronaviruses such as SARS-CoV and MERS. The broad-spectrum serine protease inhibitor, Camostat, is a TMPRSS2 inhibitor demonstrated to protect mice with lethal SARS-CoV infections (3).
