| | Ctrl | Chymotrypsin A CTRA-1; Belongs to the peptidase S1 family. (264 aa) |
| | F11 | Coagulation factor XIa heavy chain; Factor XI triggers the middle phase of the intrinsic pathway of blood coagulation by activating factor IX. (624 aa) |
| | Plat | Tissue-type plasminogen activator chain A; Converts the abundant, but inactive, zymogen plasminogen to plasmin by hydrolyzing a single Arg-Val bond in plasminogen. By controlling plasmin-mediated proteolysis, it plays an important role in tissue remodeling and degradation, in cell migration and many other physiopathological events; Belongs to the peptidase S1 family. (559 aa) |
| | F10 | Activated factor Xa heavy chain; Factor Xa is a vitamin K-dependent glycoprotein that converts prothrombin to thrombin in the presence of factor Va, calcium and phospholipid during blood clotting. (493 aa) |
| | F7 | Coagulation factor VII; Initiates the extrinsic pathway of blood coagulation. Serine protease that circulates in the blood in a zymogen form. Factor VII is converted to factor VIIa by factor Xa, factor XIIa, factor IXa, or thrombin by minor proteolysis. In the presence of tissue factor and calcium ions, factor VIIa then converts factor X to factor Xa by limited proteolysis. Factor VIIa will also convert factor IX to factor IXa in the presence of tissue factor and calcium (By similarity). (446 aa) |
| | F9 | Coagulation factor IXa heavy chain; Factor IX is a vitamin K-dependent plasma protein that participates in the intrinsic pathway of blood coagulation by converting factor X to its active form in the presence of Ca(2+) ions, phospholipids, and factor VIIIa. (471 aa) |
