Protein C Information and Side Effects
Protein C is a major physiological anticoagulant. It is a vitamin K-dependant serine protease enzyme (EC 18.104.22.168) that is activated by thrombin into activated protein C (APC). The activated form (with protein S as a cofactor) degrades Factor Va and Factor VIIIa.
