| Research Abstract |
We have explored a mechanism of protein aggregation in amyotrophic lateral sclerosis and found that apo SOD1 and FALS mutant SODs become a substrate for transglutaminase. We could detect soluble oligomeric SODls by high-resolution clear native polyacrylamide gel electrophoresis (hrCN-PAGE). Moreover, hrCN-PAGE can be followed by in-gel activity assay, which revealed enzymatic activities on some oligomeric SODIs from both wild type and FALS mutants.
