Informations
A cofactor is a chemical substance, which binds to a protein, and which is necessary for the biological activity of the latter. These proteins are often enzymes, and coFactors can be thought of as "helper molecules" aiding in biochemical transformations. Protein S is a 69 kDa-dependent vitamin K eglycoprotein synthesized by hepatocytes, endothelial cells, megakaryodytes and osteoblasts. It is a physiological inhibitor of coagulation.
Protein S acts as a cofactor of activated protein C by promoting the inactivation by proteaolysis of factors Va and VIIIa.
Protein S inhibits the activation of prothrombin and the formation of the prothrombinase complex on phospholipids as well as the activation of FX.
