| Outline of Final Research Achievements |
Prion diseases are fatal neurodegenerative diseases, with no effective treatment. In this study, we firstly categories antiprion compounds and showed some compounds stabilized the native conformation. We then identified fluctuations in prion protein important for its conformational conversion using NMR spectroscopy. We also found new anti-prion compounds including RNA aptamer and tacrolimus. We lastly reviewed importance of cavities for protein function and evolution. This study indicated suppression of conformational fluctuations may be a useful strategy for drug development of neurodegenerative diseases. This study also indicated that a wide range of conformational space needed to be explored.
