Antithrombin (AT) is a small glycoprotein that inactivates several enzymes of the coagulation system. It is a 464-amino-acid protein produced by the liver.It contains three disulfide bonds and a total of four possible glycosylation sites. α-Antithrombin is the dominant form of antithrombin found in blood plasma and has an oligosaccharide occupying each of its four glycosylation sites.
Thrombin–antithrombin complex (TAT) is a protein complex of thrombin and antithrombin. [1] [2] It is a marker of net activation of coagulation. [3] Formation and ...
In mammals, there is normally occurring anti-thrombin activity (antithrombin III), which can be distinguished from autoimmune anti-thrombin. Anti-thrombin antibodies can react with both types of thrombin in the antithrombin-thrombin complex. [1] Antibodies (IgG) against thrombin can strongly inhibit its activity. [2]
Heparin increases the affinity of antithrombin to thrombin (as well as factor Xa). The direct thrombin inhibitors, a newer class of medication, directly inhibit thrombin by binding to its active site. Recombinant thrombin is available as a powder for reconstitution into aqueous solution.
Antithrombin III deficiency (abbreviated ATIII deficiency) is a deficiency of antithrombin III. This deficiency may be inherited or acquired. [ 1 ] It is a rare hereditary disorder that generally comes to light when a patient suffers recurrent venous thrombosis and pulmonary embolism , and repetitive intrauterine fetal death (IUFD). [ 2 ]
Heparin, also known as unfractionated heparin (UFH), is a medication and naturally occurring glycosaminoglycan. [3] [4] Heparin is a blood anticoagulant that increases the activity of antithrombin. [5]
Thrombin demonstrates a high level of allosteric regulation. [2] Allosterism in thrombin is regulated by the exosites 1 and 2 and the sodium binding site. A recent patent review has shown that the general consensus among researchers is that allosteric inhibitors may provide a more regulatable anticoagulant. [3]
An antithrombotic agent is a drug that reduces the formation of blood clots (). [1] [2] Antithrombotics can be used therapeutically for prevention (primary prevention, secondary prevention) or treatment of a dangerous blood clot (acute thrombus).
