OrganismSaccharomyces cerevisiae (chronological)
Aging PhenotypeLife-span extension
Allele TypeOverexpression
DescriptionOverexpression of SOD1 in combination iwth overexpression of SOD2 increases stationary phase survival by 30% (Fabrizio et al., 2003).
Gene FunctionCytosolic copper-zinc superoxide dismutase.
Other PhenotypesDeletion of SOD1 decreases survival in stationary phase (Longo et al., 1996).
Deletion of SOD1 causes sensitivity to hyperoxia as well as methionine and lysine auxotrophies (Longo et al., 1997).
