General description
Protein C from human plasma is encoded by the gene PROC. In human chromosome, the gene is localised on chromosome 2q14. Activated protein C (APC) cleaves protease activated receptor 1 (PAR1) resulting in cytoprotective and anti-inflammatory effects. Clinical trials with APC implicates its use in treating severe early onset preeclampsia in pregnant women and prolongs pregnancy and helps in perinatal outcomes.
Application
Protein C from human plasma has been used for pre-treatment of endothelial cells prior to antibody-inhibition assay. It has also been used in activated protein C (APC) assay to determine its inhibitory effect on copper.
Biochem/physiol Actions
In addition, activated protein C has been shown to inhibit TNF-α induced expression of the inflammatory proteins VCAM, ICAM-I, and Ilk-8 in endothelial cells.
Protein C is a plasma, vitamin κ-dependent zymogen of a serine protease that can inhibit blood coagulation by inhibiting thrombin formation, selectively inactivating Factors Va and VIIIa.
Protein C is a plasma, vitamin κ-dependent zymogen of a serine protease that can inhibit blood coagulation by inhibiting thrombin formation, selectively inactivating Factors Va and VIIIa. The Protein C anticoagulant pathway is triggered when thrombin binds to the endothelial cell proteoglycan, thrombomodulin. This complex, which cannot clot blood, is a potent activator of the protein C zymogen. Activation involves the release of a dodecapeptide from the N-terminal domain of the heavy chain. The activated Protein C (APC) then binds to protein S on cell surfaces and inactivates the coagulation factors Va and VIIIa by proteolysis. APC has also been shown to bind to receptors on the endothelium of large blood vessels.
