  • TMPRSS2 isoform 1 colocalizes with HA and cleaves and activates hemagglutinin (HA)
  • having extended N-terminal cytoplasmic domain (isoform 1)
  • activates the SARS-CoV spike protein for cathepsin L-independent entry into target cells

    basic FUNCTION
  • may contribute to prostate tumour metastasis via the activation of F2RL1
  • important role for TMPRSS2 and possibly TMPRSS4 in influenza virus replication and highlight the former protease as a potential therapeutic target
  • TMPRSS2 and TMPRSS11D are expressed by important influenza and SARS-coronavirus target cells and could thus support viral spread in the human host
  • TMPRSS2 and TMPRSS11D can cleave and activate the spike protein (S) of the severe acute respiratory syndrome coronavirus (SARS-CoV) for membrane fusion
  • plays a major role in in vivo replication of emerging H7N9 and seasonal influenza viruses
  • cleaves and activates the influenza virus and coronavirus surface protein
  • activate the SARS- and MERS-CoV S proteins for cathepsin B/L-independent host cell entry, presumably by cleaving the S proteins at or close to the cell surface
  • activates HCV infection at the postbinding and entry stage
  • is a novel membrane-anchored mediator in cancer pain
  • SARS-2-S employs TMPRSS2 for S protein priming in human lung cells
  • may also play an important role in SARS-CoV-2 cell entry
  • TMPRSS2 is also likely to be a key protease for SARS-CoV-2 replication
    a component
    small molecule
  • TMPRSS2 and potentially related proteases promote SARS-CoV entry by two separate mechanisms: ACE2 cleavage, which might promote viral uptake, and SARS-S cleavage, which activates the S protein for membrane fusion
  • TMPRSS2 was found to compete with the metalloprotease ADAM17 for ACE2 processing, but only cleavage by TMPRSS2 resulted in augmented SARS-S-driven entry
  • role for inflammation-induced oxidative stress in the formation of DNA breaks leading to recurrent TMPRSS2-ERG gene fusions

    tumoral     --over  
    in prostate carcinoma, with down-regulation of KLK11 gene in advanced and more aggressive tumors may open the feasibility of being used as biomarkers distinguishing the tumor aggressiveness
    tumoral fusion      
    with ERG, ETV1 and ETV4 in prostate cancer
    tumoral somatic mutation translocation    
    Loss of PTEN and concomitant activation of AKTcould act in partnership with the TMPRSS2-ERG fusion protein to promote progression to prostate cancer
    tumoral fusion      
    TMPRSS2-ERG gene fusions were observed in 44p 100 of prostate cancer, and over 90p100 of these fusions occurred in ERG exons 3 or 4
    Variant & Polymorphism
    Candidate gene
  • development of the TMPRSS2-ERG fusion gene is a noninvasive tumor marker for therapy assessment, risk stratification, and relapse detection to improve personalized therapy strategies for patients with prostate cancer
  • urinary TMPRSS2:ERG might become a valuable test not only for diagnosing PCa but also for distinguishing the aggressive tumors from the indolent ones
  • Therapy target
    TMPRSS2-related therapeutic agents may be a promising countermeasure against the current and new outbreaks of CoVs
  • Tmprss2 plays a crucial role in viral spread within the airway of murine models infected by SARS-CoV and MERS-CoV and in the resulting immunopathology
