Title: Tissue Factor Pathway Inhibitor
Additional Names: TFPI; lipoprotein-associated coagulation inhibitor; LACI
Literature References: Endogenous inhibitor of the tissue factor mediated pathway of blood coagulation. Glycoprotein containing 276 amino acid residues; mol wt ~42 kDa. Structure consists of an acidic amino terminal region followed by three tandem Kunitz-type protease inhibitory domains and a basic carboxy terminal region. Forms a quaternary inhibitory complex with tissue factor, factor VIIa and factor Xa to block the formation of thrombin from prothrombin. Isoln of factor produced by hepatoma cells: G. J.
