Description

Protein S is a vitamin K-dependent cofactor for activated protein C. Approximately 40% of protein S is present in the blood in the active free form,
and approximately 60% is bound to C4b binding protein and therefore remains inactive.

Protein S deficiencies can be hereditary or acquired. Acquired deficiency can be observed during pregnancy, oral anticoagulant therapy, oral contraceptives,
liver disease, in newborns, and in other clinical situations. Protein S deficiency may be associated with a high risk of developing venous thromboembolism, particularly in young people.
