  • initiator-like element and potential regulatory element including SREBP, SP1, ERE
  • androgen-responsive promoter elements
  • an enhancer at 13 kb upstream of the TMPRSS2 transcription start site is crucial for the androgen regulation of the TMPRSS2 gene, and the GATA-2 binding sites are involved in the enhancer activity

    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
  • HPN and TMPRSS2 colocalize on the cell surface with the secreted serine proteases KLK4 and KLK14, only in membrane protrusions, suggesting that reciprocal proteolytic interactions occur in defined cellular structures that are important during cancer dissemination for cell migration, invasion and survival
  • 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

    small molecule
    protein
  • 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
  • in contrast with HPN, TMPRSS2 degrades KLK14, and TMPRSS2 cleavage is mediated by KLK14
