Tissue factor pathway inhibitor: the carboxy-terminus is required for optimal inhibition of factor Xa.
Tissue factor pathway inhibitor (TFPI) is a multivalent Kunitz-type protease inhibitor that binds to and inactivates factor Xa directly, and in a factor Xa-dependent fashion inhibits the factor VIIa/tissue factor catalytic complex. TFPI is a slow, tight-binding, competitive, and reversible inhibitor of factor Xa, in which the formation of an initial encounter complex between TFPI and factor Xa ...
متن کاملCaveolae optimize tissue factor-Factor VIIa inhibitory activity of cell-surface-associated tissue factor pathway inhibitor.
TFPI (tissue factor pathway inhibitor) is an anticoagulant protein that prevents intravascular coagulation through inhibition of fXa (Factor Xa) and the TF (tissue factor)-fVIIa (Factor VIIa) complex. Localization of TFPI within caveolae enhances its anticoagulant activity. To define further how caveolae contribute to TFPI anticoagulant activity, CHO (Chinese-hamster ovary) cells were co-transf...
متن کاملPresence of tissue factor pathway inhibitor in human atherosclerotic plaques is associated with reduced tissue factor activity.
BACKGROUND Plaque disruption and exposure of subendothelial procoagulants such as tissue factor (TF) to circulating factor VII/VIIa (FVII/VIIa) lead to intravascular thrombosis. Tissue factor pathway inhibitor (TFPI) is an endogenous inhibitor of TF-induced coagulation that binds to factor Xa and the TF-FVIIa catalytic complex in a two-step process. The aim of this study was to determine the ex...

15 صفحه اولA novel anticoagulant activity assay of tissue factor pathway inhibitor I (TFPI).
Tissue factor (TF) pathway inhibitor I (TFPI) is the physiological inhibitor of TF-induced blood coagulation. Circulating blood contains full-length TFPI and TFPI truncated at the C-terminal end. Previous studies have shown that full-length TFPI exerts a stronger anticoagulant effect on diluted prothrombin time (DPT) than truncated TFPI, and it has been suggested that full-length TFPI is biolog...
