Does protein C inactivate Factor 5?
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.
Is Thrombophilia the same as protein C deficiency?
Protein C deficiency is a congenital or acquired condition that leads to increased risk for thrombosis. Congenital protein C deficiency is one of several inherited thrombophilias, which are a heterogeneous group of genetic disorders associated with an elevated risk of venous thromboembolism.
Is factor V Leiden a protein?
A particular mutation in the F5 gene causes factor V Leiden thrombophilia. The F5 gene provides instructions for making a protein called coagulation factor V. This protein plays a critical role in the coagulation system, which is a series of chemical reactions that forms blood clots in response to injury.
