Protein C, also known as autoprothrombin IIA and blood coagulation factor XIV, [5]: 6822 [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.
Coagulation, also known as clotting, is the process by which blood changes from a liquid to a gel, forming a blood clot. It results in hemostasis, the cessation of blood loss from a damaged vessel, followed by repair. The process of coagulation involves activation, adhesion and aggregation of platelets, as well as deposition and maturation of ...
A representation of the 3D structure of the protein myoglobin showing turquoise α-helices. This protein was the first to have its structure solved by X-ray crystallography. Toward the right-center among the coils, a prosthetic group called a heme group (shown in gray) with a bound oxygen molecule (red).
Coagulation factor VII (EC 3.4.21.21, formerly known as proconvertin) is a protein involved in coagulation and, in humans, is encoded by gene F7. It is an enzyme of the serine protease class. Once bound to tissue factor released from damaged tissues, it is converted to factor VIIa (or blood-coagulation factor VIIa , activated blood coagulation ...

A thrombus (pl. thrombi), colloquially called a blood clot, is the final product of the blood coagulation step in hemostasis. There are two components to a thrombus: aggregated platelets and red blood cells that form a plug, and a mesh of cross-linked fibrin protein. The substance making up a thrombus is sometimes called cruor.
Tissue factor, also called platelet tissue factor or Coagulation factor III, [5] is a protein present in subendothelial tissue and leukocytes which plays a major role in coagulation and, in humans, is encoded by F3 gene. Its role in the blood clotting is the initiation of thrombin formation from the zymogen prothrombin.
Kringle domains are autonomous protein domains that fold into large loops stabilized by 3 disulfide linkages. These are important in protein –protein interactions with blood coagulation factors. Their name refers to the Kringle , a Scandinavian pastry which they somewhat resemble.
