  • Function
    Responsible for initiating activation of pancreatic proteolytic proenzymes (trypsin, chymotrypsin and carboxypeptidase A). It catalyzes the conversion of trypsinogen to trypsin which in turn activates other proenzymes including chymotrypsinogen, procarboxypeptidases, and proelastases.
  • Tissue specificity
    Intestinal brush border.
  • Involvement in disease
    Defects in TMPRSS15 are a cause of enterokinase deficiency (ENTKD) [MIM:226200]; a life-threatening intestinal malabsorption disorder characterized by diarrhea and failure to thrive.
  • Sequence similarities
    Belongs to the peptidase S1 family.
    Contains 2 CUB domains.
    Contains 2 LDL-receptor class A domains.
    Contains 1 MAM domain.
    Contains 1 peptidase S1 domain.
    Contains 1 SEA domain.
    Contains 1 SRCR domain.
  • Post-translational
    modifications
    The chains are derived from a single precursor that is cleaved by a trypsin-like protease.
  • Cellular localization
    Membrane.
  • Information by UniProt
