Description

The recombinant human transmembrane protease serine 2 (TMPRSS2) (R255Q) is expressed in the mammalian cells with N-terminally tagged 10xHis motif. Its expression region corresponds to amino acid residues 106-493 of the human TMPRSS2 protein. The purity of this recombinant protein is over 90% determined by the SDS-PAGE. Its endotoxin content is less than 1.0 EU/ug measured by the LAL method. Validation of its ability to cleave fluorogenic peptide substrate (Boc-Gln-Ala-Arg-AMC) shows this protein is active. It is available now. The target protein TMPRSS2 is a cell surface protein mainly expressed by endothelial cells across the respiratory and digestive tracts. It participates in the cleavage of peptide bonds of proteins that have serine as the nucleophilic amino acid within the active site acts. Emerging evidence has shown that TMPRSS2 acts to activate the SARS-CoV-2 spike (S) protein and facilitate viral entry into host cells.

Target Background

Function

Plasma membrane-anchored serine protease that participates in proteolytic cascades of relevance for the normal physiologic function of the prostate. Androgen-induced TMPRSS2 activates several substrates that include pro-hepatocyte growth factor/HGF, the protease activated receptor-2/F2RL1 or matriptase/ST14 leading to extracellular matrix disruption and metastasis of prostate cancer cells. In addition, activates trigeminal neurons and contribute to both spontaneous pain and mechanical allodynia.; (Microbial infection) Facilitates human coronaviruses SARS-CoV and SARS-CoV-2 infections 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. Upon SARS-CoV-2 infection, increases syncytia formation by accelerating the fusion process. Proteolytically cleaves and activates the spike glycoproteins of human coronavirus 229E (HCoV-229E) and human coronavirus EMC (HCoV-EMC) and the fusion glycoproteins F0 of Sendai virus (SeV), human metapneumovirus (HMPV), human parainfluenza 1, 2, 3, 4a and 4b viruses (HPIV). Essential for spread and pathogenesis of influenza A virus (strains H1N1, H3N2 and H7N9); involved in proteolytic cleavage and activation of hemagglutinin (HA) protein which is essential for viral infectivity.
