  • Function

    Cleaves the alpha-chain at multiple sites and the beta-chain between 'Lys-53' and 'Lys-54' but not the gamma-chain of fibrinogen and therefore does not initiate the formation of the fibrin clot and does not cause the fibrinolysis directly. It does not cleave (activate) prothrombin and plasminogen but converts the inactive single chain urinary plasminogen activator (pro-urokinase) to the active two chain form. Activates coagulation factor VII.
  • Tissue specificity

    Ubiquitously expressed.
  • Sequence similarities

    Belongs to the peptidase S1 family.
    Contains 3 EGF-like domains.
    Contains 1 kringle domain.
    Contains 1 peptidase S1 domain.
  • Post-translational

    Proteolytic cleavage at Gly-23 or Met-27 can give rise to the 50 kDa heavy chain and cleavage at Arg-313 or Lys-319 can give rise to the 27 kDa light chain. The heavy chain can undergo further proteolytic cleavage at Lys-169 or Arg-170 to give rise to 2 inactive 26 kDa fragments and the light chain can undergo further proteolytic cleavage at Arg-480 to give rise to inactive 17 kDa and 8 kDa fragments.
  • Cellular localization

    Secreted. Secreted as an inactive single-chain precursor and is then activated to a heterodimeric form.
