Abstract excerpt
BACKGROUND: The protein ZPI (Z-dependent protease inhibitor) binds to PZ (protein Z), which enables ZPI to inhibit membrane-bound FXa (activated factor X). ZPI also inhibits FXIa (activated factor XI) independently of PZ. METHODS: To study the PZ-independent ZPI function, we tested the in vitro and in vivo effect of disrupting the ZPI-PZ interaction by mutating ZPI Asp 293 to Ala (D293A). RESULTS: D293A mutation...
