Background: TMPRSS4

TMPRSS4, previously known as TMPRSS3, is a 437 amino acid type II transmembrane serine protease located on human chromosome 11q23.3 that encodes 5 isoforms containing a complete coding sequence. This serine protease has a predicted molecular weight of 48 kDa with 2 glycosylation sites and the cleaved soluble protease domain has been detected in cell culture media. Functions of TMPRSS4 include embryo development, viral infection, and cancer. TMPRSS4 plays a role in the epithelial-mesenchymal transition (EMT) process and mediates cell invasion, migration, proliferation and metastasis. Overexpression of TMPRSS4 has been reported for multiple solid tumors including pancreatic, ovarian, thyroid, colorectal, lung, breast, cervical, gallbladder, gastric, and liver cancer, and has been associated with poor overall survival and reduced time to tumor progression (1,2).
TMPRSS4 has also been shown to play a 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 or potentially by TMPRSS4 at the cell surface to facilitate viral entry (3).
