The present invention relates to the isolation and identification of novel baboon nucleic acid molecules and proteins and polypeptides encoded by such nucleic acid molecules, or degenerate variants thereof, which proteins and polypeptides comprise novel baboon thrombin-activatable fibrinolysis inhibitors or “TAFI” enzyme molecules. Because the novel baboon TAFI proteins and polypeptides of the invention inhibit the breakdown of blood clots, they may be therapeutically useful for the treatment of blood disorders wherein clotting needs to be regulated or promoted, such as hemophilia or von Willebrand's disease or in other situations, such as trauma, wherein blood clotting or coagulation needs to be regulated or promoted. The sequences of the invention are also useful in screening methods for the identification of compounds that modulate the expression of the baboon TAFI nucleic acids and/or the activity of the baboon TAFI proteins and polypeptides of the invention. Such agonist or antagonist compounds may be useful in the treatment of various blood clotting disorders and conditions requiring hemostatic control such as hemophilia or various thrombotic diseases such as deep venous thrombosis, coronary artery disease, stroke associated with atrial fibrillation and recurrent thrombosis following stroke or myocardial infarction.
本发明涉及新型狒狒核酸分子和由这种核酸分子编码的蛋白质和多肽或其退化变体的分离和鉴定,这些蛋白质和多肽包括新型狒狒凝血酶活化纤溶抑制剂或 "TAFI "酶分子。由于本发明的新型狒狒 TAFI 蛋白和多肽可抑制血凝块的分解,因此可用于治疗需要调节或促进凝血的血液疾病,如血友病或冯-威廉氏病,或在需要调节或促进凝血的其他情况下,如创伤。本发明的序列还可用于筛选方法,以鉴定可调节狒狒 TAFI 核酸表达和/或本发明狒狒 TAFI 蛋白和多肽活性的化合物。这种激动剂或拮抗剂化合物可用于治疗各种凝血障碍和需要止血控制的疾病,如血友病或各种血栓性疾病,如深静脉血栓、冠状动脉疾病、伴有心房颤动的中风和中风或心肌梗塞后的复发性血栓形成。
