Outline of Final Research Achievements |
Accumulation of misfolded proteins due to inappropriate stabilization results in neurodegenerative diseases including amyotrophic lateral sclerosis (ALS). In this study, we clarify structural differences of carboxyl terminal fragments of ALS-causative TDP43 (TDP35 or TDP25) by using fluorescence resonance energy transfer (FRET) or related procedure. We elucidate that nuclear localization signal sequence (NLS)-tagged TDP25 can reduce cytotoxicity through the structural change.
