The endothelial protein C receptor (EPCR), also known as CD201, is a transmembrane glycoprotein expressed on vascular endothelial cells and functions as a negative regulator of thrombosis (1). Mature human EPCR consists of a 193 amino acid (aa) extracellular domain (ECD), a 21 aa transmembrane segment, and a 7 aa cytoplasmic tail (2). Within the ECD, human EPCR shares 63% and 66% aa sequence identity with mouse and rat EPCR, respectively. EPCR inhibits thrombosis through its interactions with Protein C, activated Protein C (APC), and Coagulation Factors VII, and VIIa (3, 4). It enhances the activation of Protein C in response to complexes of Thrombin-Thrombomodulin (5). In humans, a soluble form of EPCR can be produced by alternative splicing or ADAM17/TACE mediated shedding (6-9), and this protein inhibits the anti-coagulant activity of APC (10, 11). EPCR can be degraded on the surface of endothelial cells by Neutrophil Elastase (12). Activation of EPCR also protects vascular endothelial cells from Thrombin-induced apoptosis (13). EPCR binds to CD11b/CD18 (Mac-1) on monocytes and mediates monocyte adhesion to the vascular endothelium (14). In addition, EPCR binds to the antigen receptor on gamma δ T cells (15), promotes hematopoietic stem cell retention in the bone marrow (9), and binds to surface proteins of some species of Plasmodium, contributing to pathogenicity in severe malaria (16).
