SOD1 (147-153) human is a peptide fragment of Cu/Zn superoxide dismutase ( SOD1 ) with a high propensity to form amyloid fibrils. SOD1 (147-153) human may trigger the aggregation of full-length SOD1 and is a common molecular determinant of familial amyotrophic lateral sclerosis (fALS) and sporadic amyotrophic lateral sclerosis (sALS).
