Title

PRODUCTION OF MUTANT STREPTOKINASE RECOMBINANT PROTEIN

Pages

  179-183

Abstract

 Background: STREPTOKINASE (SK) is most widely used for treatment of myocardial infarction, however, it is the most expensive thrombolytic agent. A major drawback to SK use is the widespread presence of anti–STREPTOKINASE antibodies (Abs). These Abs cause allergic reactions and neutralize STREPTOKINASE therapeutic effects.Materials and methods: To produce an engineered variant of STREPTOKINASE being functional and less antigenic than the native molecule, we cloned and expressed STREPTOKINASE mutant gene lacking the C-terminal 42 amino acids. Recombinant protein was confirmed by western blot analysis with anti T7 monoclonal antibodies.Results: pGEMEX-1 expression vector contains T7 gene 10 protein as fusion protein immediately downstream of T7 promoter and before multiple CLONING site, STREPTOKINASE mutant gene was cloned after fusion protein.Conclusion: We cloned and expressed mutant STREPTOKINASE gene, lacking the C-terminal 42 amino acids. If mut-C42 activity was less affected by neutralizing antibodies compared with native STREPTOKINASE, this engineered variant could be a preferred alternative to native STREPTOKINASE for thrombolytic therapy.
