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.
