Background: TMPRSS2

Recombinant Transmembrane protease serine 2 (TMPRSS2), also referred to as serine protease 10 (PRSS10), is a member of the type II transmembrane serine protease (TTSP) peptidase S1 family (1). Similar to other members of the TTSP family, TMPRSS2 is produced as a zymogen and undergoes post-transcriptional modifications to allow proteolytic autoactivation into a non-catalytic chain, composed of an LDLR-A and SRCR domain, and a catalytic chain with a highly conserved serine protease (SP) domain. The TMPRSS2 SP domain uniquely contains an unpaired cysteine bordered by a hydrophobic patch thought to accommodate various binding partners (2). TMPRSS2 consists of three distinct regions, including an intracellular domain, a single-pass transmembrane domain, and an extracellular domain and can be membrane bound or found in a soluble secreted form (1, 2). The TMPRSS2 gene harbors androgen-responsive elements and expressed through the stimulation of the AR (1) in tissues with epithelial cells at high levels in prostate and relatively lower levels of expression in lungs, colon, liver, kidneys and pancreas (2-4). TMPRSS2 activates protease activated receptor 2 (PAR-2), a G-protein coupled receptor, causing the upregulation of matrix metalloproteinase-2 and -9, key proteases in the metastasis of tumor cells (5) and in prostate cancer has been shown to activate pro-hepatocyte growth factor resulting in subsequent c-MET signaling known to regulate the tumor microenvironment, immune infiltration, and immune response (6,7). TMPRSS2 expression may be involved broadly in cancer prognosis through this pathway as reported in lung adenocarcinoma and breast invasive carcinoma (7). In addition to playing a role in cancer, TMPRSS2 is the host protease determined to be responsible for processing of viral protein to facilitate host entry in several viruses including spike protein in SARS-CoV-2, SARS-CoV, and MERS-CoV and hemagglutinin in influenza A viruses (3,4,8-11). TMPRSS2 represents a prime target for therapeutic intervention in aggressive cancers and to block initial viral influenza and coronavirus infection (2, 3, 11).
