protein C

Protein C 與Antithrombin III同樣具有血液凝固抑制因子作用，為Vitamin K依存性血漿蛋白之一，Protein C與血管內壁上凝血素受體Thrombin receptor 之Thrombomosulin結合使凝血素活化此活性化Protein與 Calcium、Phospholipids及輔酵素在Protein S 的存在下，活性型的第Va factor，第Va factor分解而失去活性，除有抗凝作用外，活性化Protein C 可使組織自纖維蛋白酉每原活性劑游離增加，或促進纖溶不活化，故Protein C 、Protein S、 AntithrombinIII同樣為檢查凝固纖溶系所引起的疾病Protein C低值：擴散性血管內內凝固 Disseminated intravascular coagulation、慢性肝炎
