Endothelial protein C receptor
Endothelial protein C receptor (EPCR) also known as activated protein C receptor (APC receptor) is a protein that in humans is encoded by the PROCR gene.[5][6][7] PROCR has also recently been designated CD201 (cluster of differentiation 201).

The protein encoded by this gene is a receptor for protein C that enhances its activation. Protein C is an anti-coagulant serine protease activated by the blood coagulation pathway.
Structure
EPCR protein is an N-glycosylated type I membrane protein that enhances the activation of protein C.[7] It belongs to the MHC class I/CD1 family of proteins, that is characterized by having a deep groove, that in other proteins in the family (but not in EPCR) is usually used for antigen binding.
Like the CD1 series, EPCR has a lipid in the corresponding groove. The bound lipid in EPCR is usually phosphatidylcholine, but it may be phosphatidylethanolamine, and it contributes to protein C binding, though probably not through direct contact [8]
Clinical significance
Mutations in this gene have been associated with venous thromboembolism and myocardial infarction, as well as with late fetal loss during pregnancy.[7]
The protein is also involved in Plasmodium falciparum malaria as subtypes of the Plasmodium falciparum erythrocyte membrane protein 1 (PfEMP1) family use EPCR of the host as a receptor.[9]
