WebbJ Biol Chem. April 18, 2024. Tissue factor pathway inhibitor (TFPI), the main inhibitor of initiation of coagulation, exerts an important anticoagulant role through the factor Xa (FXa)-dependent inhibition of tissue factor/factor VIIa (FVIIa). Protein S is a TFPI cofactor, enhancing the efficiency of FXa inhibition.
