Antithrombin II is a single polypeptide chain glycoprotein (MW 61,000) with a high degree of homology with the alpha-1 antitrypsin. It is a circulating natural anticoagulant acting as a proteinase inhibitor. It is synthesized in the liver and the vascular endothelial cells. In electrophoresis of plasma it migrates in the alpha-1 region and is consumed during coagulation in vivo. Antithrombin III inhibits the action of factors IXa, Xa, XIIa, thombin and kallikrein by forming a stable complex. Heparin acts as a cofactor which greatly increases its inhibitory activities. Normal adult plasma contain an average of 0.15mg antithrombin III per ml. This can vary from 75-128%. A partial deficiency in antithrombin III activity in the plasma (<50%) will result in an increased tendency to recurrent thrombo-enbolism. Several types of congenital deficiency have been reported. Most common type 1 deficiency patients have reduced antithrombin III antigen and activity levels. Heterozygotes have levels of 25-50% of normal values.
