Proteomics (Proteome ID):UP000005640
Proteomics (Chromosome): Chromosome 11
Active Site:ACT_SITE 406 406 Charge relay system.; ACT_SITE 462 462 Charge relay system.; ACT_SITE 568 568 Charge relay system.
Activity Regulation: Inhibited by SERPINA5. {ECO:0000269|PubMed:6323392}.
Catalytic Activity: Reaction=Selective cleavage of Arg-|-Gly bonds in fibrinogen to form fibrin and release fibrinopeptides A and B.; EC=3.4.21.5;
Function [CC]: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. {ECO:0000269|PubMed:2856554}.
Site:SITE 198 199 Cleavage; by thrombin.; SITE 327 328 Cleavage; by factor Xa.; SITE 363 364 Cleavage; by factor Xa.
Tissue Specificity:Expressed by the liver and secreted in plasma.
Disease:Factor II deficiency (FA2D) [MIM:613679]: A very rare blood coagulation disorder characterized by mucocutaneous bleeding symptoms. The severity of the bleeding manifestations correlates with blood factor II levels. {ECO:0000269|PubMed:1349838, ECO:0000269|PubMed:1354985, ECO:0000269|PubMed:1421398, ECO:0000269|PubMed:14962227, ECO:0000269|PubMed:2719946, ECO:0000269|PubMed:3242619, ECO:0000269|PubMed:3567158, ECO:0000269|PubMed:3771562, ECO:0000269|PubMed:3801671, ECO:0000269|PubMed:6405779, ECO:0000269|PubMed:7792730, ECO:0000269|PubMed:7865694}. Note=The disease is caused by mutations affecting the gene represented in this entry.; Ischemic stroke (ISCHSTR) [MIM:601367]: A stroke is an acute neurologic event leading to death of neural tissue of the brain and resulting in loss of motor, sensory and/or cognitive function. Ischemic strokes, resulting from vascular occlusion, is considered to be a highly complex disease consisting of a group of heterogeneous disorders with multiple genetic and environmental risk factors. {ECO:0000269|PubMed:15534175}. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.; Thrombophilia due to thrombin defect (THPH1) [MIM:188050]: A multifactorial disorder of hemostasis characterized by abnormal platelet aggregation in response to various agents and recurrent thrombi formation. {ECO:0000269|PubMed:2825773}. Note=The disease is caused by mutations affecting the gene represented in this entry. A common genetic variation in the 3-prime untranslated region of the prothrombin gene is associated with elevated plasma prothrombin levels and an increased risk of venous thrombosis.; Pregnancy loss, recurrent, 2 (RPRGL2) [MIM:614390]: A common complication of pregnancy, resulting in spontaneous abortion before the fetus has reached viability. The term includes all miscarriages from the time of conception until 24 weeks of gestation. Recurrent pregnancy loss is defined as 3 or more consecutive spontaneous abortions. {ECO:0000269|PubMed:11506076}. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.
Pharmaceutical Application:Rx: The peptide TP508 also known as Chrysalin (Orthologic) could be used to accelerate repair of both soft and hard tissues.
Miscellaneous [CC]:Prothrombin is activated on the surface of a phospholipid membrane that binds the amino end of prothrombin and factors Va and Xa in Ca-dependent interactions; factor Xa removes the activation peptide and cleaves the remaining part into light and heavy chains. The activation process starts slowly because factor V itself has to be activated by the initial, small amounts of thrombin.; It is not known whether 1 or 2 smaller activation peptides, with additional cleavage after Arg-314, are released in natural blood clotting.; Thrombin can itself cleave the N-terminal fragment (fragment 1) of the prothrombin, prior to its activation by factor Xa.; The cleavage after Arg-198, observed in vitro, does not occur in plasma.
