Abstract excerpt
Mutations in the Cu,Zn-superoxide dismutase (SOD1) gene cause 20-25% of familial amyotrophic lateral sclerosis (ALS). Mutant SOD1 causes motor neuron degeneration through toxic gain-of-function(s). However, the direct molecular targets of mutant SOD1, underlying its toxicity, are not fully understood. In this study, we found that alpha/beta-tubulin is one of the major mutant SOD1-interacting proteins, but that...
