Protein S

Protein S is a vital protein in the human body that plays an important role in regulating blood clotting. It helps prevent excessive clot formation by acting as a cofactor for another protein called activated protein C. Together, they work to maintain a balance in the blood clotting system, ensuring that clots form when necessary (to stop bleeding) but also dissolve when they are no longer needed. A deficiency in Protein S can lead to an increased risk of abnormal blood clots, which can cause serious health issues like deep vein thrombosis or pulmonary embolism.
