Protein C ist eine Protease, die nach Aktivierung (mit Cofaktor Protein S) durch Proteolyse die Gerinnungsfaktoren Faktor. 1 Protein S ist ein Glykoprotein, das als Cofaktor des aktivierten Protein C u.a. die Blutgerinnung hemmt und die Fibrinolyse. 2 Aktiviertes Protein C komplexiert mit Protein S, um dann in der freien Blutbahn die Gerinnungsfaktoren FVa und FVIIIa durch Proteolyse zu inaktivieren. 3 Struktur und Funktion: Protein S ist ein in seiner Synthese Vitamin-K-abhängiges Protein, das in den Hepatozyten gebildet wird. Es gehört – wie auch Protein C –. 4 If you have been diagnosed with a protein C or S deficiency, it's important to talk with your provider whenever you face situations that can trigger blood clots, such as: Surgery Pregnancy Broken bones or other trauma injuries Not moving for long periods of time due to: Bedrest Long car rides or. 5 Should relatives of someone with an inherited protein C or protein S deficiency be tested? Both proteins are produced in the liver and production depends on vitamin K. Therefore low levels may be due to: Liver Liver disease Vitamin K deficiency Warfarin (Coumadin®) anticoagulant therapy (a. 6 Protein S activity is a vital part of normal blood clotting and its control. Protein S, protein C, anti-thrombin, and tissue factor pathway inhibitor (TFPI) restrict clotting and. 7 Protein C and S - antigen and activity levels are usually done by collecting a venous blood sample in citrate. They are centrifuged in the laboratory to separate plasma. The plasma is frozen in aliquots and stored at °C until analysis. The typical volume of plasma required is ml per mL. 8 Congenital C and S proteins are natural substances in the blood that help prevent blood clots. Protein C deficiency occurs in approximately 1 of every to people, whereas protein S deficiency occurs in approximately 1 of every individuals.1,2 Deficiency may be determined from a blood sample. 9 Protein C, also known as autoprothrombin IIA and blood coagulation factor XIX, [5]: [6] is a zymogen, that is, an inactive enzyme. The activated form plays an important role in regulating anticoagulation, inflammation, and cell death and maintaining the permeability of blood vessel walls in humans and other animals. protein s erhöht 10 protein c blutwert 12
