Endothelial protein C receptor (EPCR); also known as activated protein C receptor (APC receptor) or PROCR; is a receptor for Protein C. Protein C plays an important role in many metabolism processes in humans and other animals after activated by binding to Endothelial protein C receptor (EPCR). Because of the EPCR is found primarily on endothelial cells (cells on the inside of blood vessels); activated protein C is found maily near endothelial cells. Protein C is pleiotropic; with two main functions: anticoagulation and cytoprotection. Which function will be performed depend on whether or not protein C remains bind to EPCR after activated. The anticoagulation occurs when it does not. In this case; protein C functions as an anticoagulant by irreversibly proteolytically inactivating Factor Va and Factor VIIIa; turning them into Factor Vi and Factor VIIIi respectively. When still bound to EPCR; activated protein C performs its cytoprotective effects; acting on the effector substrate PAR-1; protease-activated receptor-1. To a degree; APC's anticoagulant properties are independent of its cytoprotective ones; in that expression of one pathway is not affected by the existence of the other.
