Biological function summary
Prothrombin regulates hemostasis and is part of the prothrombinase complex along with factor Xa factor Va calcium ions and phospholipids. This complex allows for the precise regulation of thrombin generation on the surface of activated platelets. By controlling the formation of thrombin prothrombin affects not only blood coagulation but also influences cell proliferation inflammation and tissue repair. The careful balance of prothrombin activation is important to prevent excessive bleeding or clot formation.
Pathways
Prothrombin is an essential component of the coagulation cascade especially the intrinsic and extrinsic coagulation pathways. In these pathways it links with proteins such as fibrinogen and factor X contributing to the amplification and perpetuation of thrombin generation. Additionally thrombin produced from prothrombin engages in a feedback loop to further enhance factor V VIII and XI activation. Through these actions prothrombin helps maintain normal coagulation but must be tightly regulated to prevent thrombotic complications.

General info
Function
Thrombin, which cleaves bonds after Arg and Lys, converts fibrinogen to fibrin and activates factors V, VII, VIII, XIII, and, in complex with thrombomodulin, protein C. Functions in blood homeostasis, inflammation and wound healing. Activates coagulation factor XI (F11); activation is promoted by the contact with negatively charged surfaces (PubMed : 2019570, PubMed : 21976677). Triggers the production of pro-inflammatory cytokines, such as MCP-1/CCL2 and IL8/CXCL8, in endothelial cells (PubMed : 30568593, PubMed : 9780208).
Sequence similarities
Belongs to the peptidase S1 family.
Post-translational modifications
The gamma-carboxyglutamyl residues, which bind calcium ions, result from the carboxylation of glutamyl residues by a microsomal enzyme, the vitamin K-dependent carboxylase. The 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.. N-glycosylated. N-glycan heterogeneity at Asn-121: Hex3HexNAc3 (minor), Hex4HexNAc3 (minor) and Hex5HexNAc4 (major). At Asn-143: Hex4HexNAc3 (minor) and Hex5HexNAc4 (major).. In the penultimate step of the coagulation cascade, prothrombin is converted to thrombin by the prothrombinase complex composed of factor Xa (F10), cofactor Va (F5), and phospholipids. This activation requires factor Xa-catalyzed sequential cleavage at 2 sites, Arg-314 and Arg-363, along 2 possible pathways. In the first pathway, the first cleavage occurs at Arg-314, leading to the formation of the inactive intermediate prethrombin-2. This pathway preferentially occurs on platelets and in the absence of cofactor Va. In the second pathway, the first cleavage occurs at Arg-363, which separates protease domain into 2 chains that remain connected through a disulfide bond and generates the active intermediate meizothrombin. The presence of cofactor Va directs activation along the meizothrombin pathway and greatly accelerates the rate of cleavage at Arg-363, but has a smaller effect on the cleavage of meizothrombin at Arg-314. Meizothrombin accumulates as an intermediate when prothrombinase is assembled on the membrane of red blood cells.
