Schematic diagram of the blood coagulation and protein C pathways. In the blood coagulation pathway, thrombin acts to convert factor XI to XIa, VIII to VIIIa V to Va, fibrinogen to fibrin. In addition, thrombin promotes platelet activation and aggregation via activation of protease-activated receptors on the cell membrane of the platelet. Thrombin also cross over into the protein C pathway by converting protein C into APC. APC in turn converts factor V into Vi, and VIIIa into VIIIi. Finally APC activates PAR-1 and EPCR.
Role of thrombin in the blood coagulation cascade

Prothrombin (coagulation factor II) is encoded in the human by the F2-gene. It is proteolytically cleaved during the clotting process by the prothrombinase enzyme complex to form thrombin.

Thrombin (Factor IIa) (EC 3.4.21.5, fibrose, thrombase, thrombofort, topical, thrombin-C, tropostasin, activated blood-coagulation factor II, E thrombin, beta-thrombin, gamma-thrombin) is a serine protease, that converts fibrinogen into strands of insoluble fibrin, as well as catalyzing many other coagulation-related reactions.[5][6]
