| Research Abstract |
SOD1 is a major causative protein of familial amyotrophic lateral screosis (fALS). I found that fALS linked mutant SOD1 proteins are specifically accumulated in mitochondria-ER associated membrane (MAM) fraction. The toxic mechanisms by this event, however, are still unknown. I hypothesized that Sigma-1 receptor (SigR1), which is a major MAM protein was inhibited by the accumulation of mutant SOD1 proteins in MAM. In this study, I found two novel finding (1) SigR1 was directly interacted with Kv2.1 and Kv4.2 (2) SigR1 was related with the localization of Kv2.1. Although I need to investigate these results more, these findings might be contributed to elucidation of the pathomechanism of fALS.
