Application

[Tyr(SO3H)63]-hirudin fragment 54-65 has been used to study the effect of thrombin in presence of leupeptin. It is also used to study the effect of hirudin peptide on the thrombin-rHCII (recombinant heparin cofactor II)-L444R (leucine 444 to arginine) complex separation.

Biochem/physiol Actions

Hirudin fragment that binds to the regulatory exosite I on thrombin and the regulatory proexosite I on prothrombin.
Hirudin fragment that binds to the regulatory exosite I on thrombin and the regulatory proexosite I on prothrombin. The interaction with thrombin prevents the thrombin-induced activation of clotting factor V. The interaction with prothrombin inhibits the formation of thrombin by factor Xa in the presence of factor Va.

European journal of biochemistry, 259(3), 643-650 (1999-03-27)
We investigated the regulation of arachidonic acid liberation catalyzed by group-IV cytosolic phospholipase A2 (cPLA2) in human platelets upon stimulation with thrombin through interaction with protease-activated receptor-1 (PAR-1) or glycoprotein Ib. Leupeptin, a protease inhibitor, completely inhibited thrombin-induced arachidonic acid
