Summary
The protein C anticoagulant pathway plays a crucial role as a regulator of the blood
clotting cascade. Protein C is activated on the vascular endothelial cell membrane
by the thrombin-thrombomodulin complex. Once formed, activated protein C (APC) down-regulates
thrombin formation by inactivating factors (F)Va and FVIIIa. Endothelial protein C
receptor (EPCR) is able to bind protein C and increase the rate of protein C activation.
Normal APC generation depends on the precise assemblage, on the surface of endothelial
cells, of thrombin, thrombomodulin, protein C and EPCR.Therefore, any change in the
efficiency of this assemblage may cause reduced/increased APC generation and modify
the risk of thrombosis. This review highlights the different mutations/polymorphisms
reported in the EPCR gene and their association with the risk of thrombosis.
