Targeting the membrane-anchored serine protease testisin with a novel engineered anthrax toxin prodrug to kill tumor cells and reduce tumor burden
The membrane-anchored serine proteases are a unique group of trypsin-like serine proteases that are tethered to the cell surface via transmembrane domains or glycosyl-phosphatidylinositol-anchors. Overexpressed in tumors, with pro-tumorigenic properties, they are attractive targets for protease-activated prodrug-like anti-tumor therapies. Here, we sought to engineer anthrax toxin protective ant...
متن کاملThe cutting edge: membrane-anchored serine protease activities in the pericellular microenvironment.
The serine proteases of the trypsin-like (S1) family play critical roles in many key biological processes including digestion, blood coagulation, and immunity. Members of this family contain N- or C-terminal domains that serve to tether the serine protease catalytic domain directly to the plasma membrane. These membrane-anchored serine proteases are proving to be key components of the cell mach...
متن کاملThe membrane-anchored serine protease, TMPRSS2, activates PAR-2 in prostate cancer cells.
TMPRSS2 is a type II transmembrane-bound serine protease that has gained interest owing to its highly localized expression in the prostate and its overexpression in neoplastic prostate epithelium. Once activated, the serine protease domain of TMPRSS2 is released from the cell surface into the extracellular space. PAR (protease-activated receptor)-2 belongs to a family of G-protein-coupled recep...
متن کاملDelineation of proteolytic and non-proteolytic functions of the membrane-anchored serine protease prostasin.
The membrane-anchored serine proteases prostasin (PRSS8) and matriptase (ST14) initiate a cell surface proteolytic pathway essential for epithelial function. Mice expressing only catalytically inactive prostasin are viable, unlike prostasin null mice, indicating that at least some prostasin functions are non-proteolytic. Here we used knock-in mice expressing catalytically inactive prostasin (Pr...
متن کاملTestisin, a glycosyl-phosphatidylinositol-linked serine protease, promotes malignant transformation in vitro and in vivo.
Human testisin, a serine protease, is highly expressed in ovarian cancer and premeiotic spermatocytes with relatively little expression in other normal tissues. We first showed that testisin was localized on the surface of cultured tumor cells as a glycosyl-phosphatidylinositol-linked protein. We next explored the biological function of testisin in malignant transformation through manipulation ...
