| Outline of Final Research Achievements |
ALS is a devastating neurodegenerative disease characterized by the selective motoneuron death. We have previously reported that SOD1 mutants interact with Derlin-1, leading to the motoneuron death. In addition, we have found that the zinc depletion induced the conformational change of wild-type SOD1 (SOD1WT) and the interaction between SOD1WT and Derlin-1. To evaluate the possibility that the conformationally-disordered SOD1WT could be involved in the pathogenesis of SOD1 mutation-negative ALS, we investigated the molecular mechanism of SOD1WT conformational change.
The analysis of ZIP13, a zinc transporter, that was identified as a mediator of zinc depletion-induced SOD1WT conformational change revealed the essential role of the Golgi apparatus in zinc depletion-induced SOD1WT conformational change.
