Tissue Factor Protein Overview: Sequence, Structure, Function and Protein Interaction

Tissue Factor Protein Overview

The extrinsic pathway of blood coagulation is initiated by contact of plasma factor VII (F7; 613878) with tissue factor (F3), a cellular membrane glycoprotein that normally is segregated from the bloodstream but can be exposed after tissue injury or newly synthesized in endothelial cells or leukocytes after stimulation by endotoxin and cytokines. Once formed, the tissue factor/factor VII complex converts to a complex of tissue factor and enzymatically active factor VII (F7a); this conversion leads to activation of factors X (F10; 613872) and IX (300746) and prothrombin (176930), and ultimately to formation of fibrin (134570/134580). These processes are regulated by plasma protease inhibitors and by the thrombomodulin (188040)-protein C (612283) pathway. A further regulatory mechanism in the extrinsic pathway is called tissue factor pathway inhibitor (TFPI; 152310). For a review, see Davie et al. (1991).
