NameSOD1
OrganismDrosophila melanogaster
Aging PhenotypeLife-span extension
Allele TypeOverexpression
Strainunknown
DescriptionGeneral overexpression causes up to 48% increase in life span (Sun et al., 1999). Targeted transgenic expression of hSOD1 in motorneurons alone causes 40% increase in mean and maximum life span (Parkes et al., 1998).
Gene Functionsod1 encodes a cytosolic Cu,Zn superoxide dismutase that reduces superoxide anion to hydrogen peroxide.
Other PhenotypesTargeted neuronal expression of SOD1 and CAT together abrogates life span extension by expression of SOD1 alone (Parkes et al., 1998).
