| Outline of Final Research Achievements |
We generated the peptides consisting of mitochondrial localizing signal peptide derived from Cdk5rap1 and poly arginine (9R). We incubated primary cultured myocardial cells, skeletal muscle cels and neurons with the peptides. The peptides were localized on mitochondria. Moreover, we generated the liposomes containing eperisone, which are conjugated with the mitocondrial signal peptide. When applied the liposomes to Cdk5rap1-deficient skeletal muscle cells, the liposomes were localized in mitochondria and mitochondrial functions such as compel activities, mitochondrial membrane potential and the translation of mitochondrial proteins were improved.
