Pharmacodynamics

Protein S acts as an anticoagulant serves as a negative feedback mechanism in the coagulation cascade 1.

Mechanism of action

Thrombin converts protein C to activated protein C (APC) 1. Protein S functions as a cofactor for APC and together they proteolytically cleave factor Va and VIIIa 1 2. This inhibits the activities of the prothrombinase and tenase complexes respectively and leads to a reduction in thrombin generation. The reduction in thrombin generation suppresses the coagulation cascade preventing additional clotting from occuring. Protein S is suggested to inhibit factors Va and Xa through protein-protein interactions 4 1. Protein S is also suggested to inhibit production of factor Xa by the tenase complex by competing for binding to phospholipids via its gamma-carboxyglutamic acid domain.

Protein S is thought to exert an anti-inflammatory effect in addition to its anticoagulant properties. The protein S-C4b-binding protein complex is believed to bind to phosphotidylserines on the cell membranes of apoptotic cells and interact with macrophages, signalling them to phagocytose the cell before it can rupture 3.
