" /> Prothrombin - CISMeF





Preferred Label : Prothrombin;

NCIt synonyms : EC 3.4.21.5; Factor II; Coagulation Factor II; Prothrombin Gene Product; F2;

NCIt definition : Prothrombin (622 aa, 70 kDa) is encoded by the human F2 gene. This protein plays a role in both coagulation and proteolysis of fibrinogen.;

NCIt note : Prothrombin catalyzes the cleavage of Arg-Gly bonds in fibrinogen to form fibrin and release fibrinopeptides A and B. (UniProt); Prior to secretion, prothrombin is modified to have gamma-carboxyglutamyl residues, resulting from the carboxylation of glutamyl residues by vitamin K-dependent gamma-carboxylase. These modified residues are necessary for the calcium-dependent interaction with a negatively charged phospholipid surface, which is essential for the conversion of prothrombin to thrombin. (UniProt); Prothrombin activates factors V, VII, VIII, XIII, and, in complex with thrombomodulin, protein C. (UniProt); Prothrombin protein can be cleaved into the following 4 chains: activation peptide fragment 1, activation peptide fragment 2, thrombin light chain, thrombin heavy chain. (UniProt);
