Target description

Tissue factor (UniProt: P13726; also known as TF, Coagulation factor III, Thromboplastin, CD142) is encoded by the F3 gene (Gene ID: 2152) in human. Tissue factor (TF) is an integral membrane protein that serves as a high-affinity receptor and cofactor for factor VII/VIIa. It is expressed on perivascular cells and epithelial cells at organ and body surfaces where it forms a hemostatic barrier. It is also reported to provide hemostatic protection to brain, lung, and heart. In normal healthy individuals, levels of TF are very low. Cell-surface levels of TF do not display any directly correlation with its procoagulant activity indicating that TF exists on the cell surface as dormant (encrypted) and active (de-encrypted) form. This allows for a rapid hemostatic response without a need for transcriptional upregulation of the F3 gene. TF normally exists in a partially encrypted state and its de-encryption on circulating monocytes, platelets or endothelial cells by inflammatory mediators can lead to thrombosis. It initiates blood coagulation by forming a complex with circulating factor VII or VIIa and this complex activates factor IX and X by specific, limited proteolysis. TF expression by nonvascular cells plays an essential role in homeostasis; however, TF expression by vascular cells can induce life-threatening intravascular thrombosis in various diseases, such as sepsis, cancer, and atherosclerosis. Inhibition of TF-Factor VIIa activity is shown to reduce coagulation and mortality in animal models of sepsis. Many cancer cells express large amounts of TF, which contributes to tumor angiogenesis and growth. Cancer cells can release TF-positive microparticles into the circulation that can trigger venous thromboembolism. TF on circulating tumor cells can also coat cells with fibrin that traps them within the microvasculature and promote hematogenous metastasis. (Ref.: Carson, S.D., et al. (1987).
