| Research Abstract |
TDP-43 is one of a causative protein of amyotrophic lateral sclerosis(ALS), and generally related with the ALS pathology. The mechanism of motor neuron degeneration by TDP-43, however, is still unknown.
The representative of this study(I) identified p47 as a novel protein interacted with TDP-43.I elucidated that p47 interacts with not ALS-linked TDP-43 mutant proteins but wild-type. In addition, I clarified that the half-life of ALS-linked mutant TDP-43 protein is longer than that of wild-type. Early onset of ALS correlates with increased stability of familial ALS-linked mutant TDP-43 proteins.
