| Research Abstract |
Habutobin expresses antithrombotic action by defibrinogenation, acceleration of fibrinolysis, and inhibition of platelet aggregation. Structural determination of the site responsible for the action of habutobin underlies the development of antithrombotic agents with multiple pharmacological actions. Habutobin cDNA was cloned and 4 fragments of recombinant habutobin (habu-mut 1, 2, 3 and 4) each with different target sites were constructed. It was found that habu-mut2 suppressed collagen-induced platelet aggregation by approximately 10%, and habu-mut3 suppressed it by approximately 20-30%. Novel antithrombotic agents can be developed by structural analysis.
