OrganismSaccharomyces cerevisiae (chronological)
Aging PhenotypeLife-span extension
Allele TypeOverexpression
DescriptionOverexpression of SOD2 in combination with overexpression of SOD1 increases stationary phase survival by 30% (Fabrizio et al., 2003).
Gene FunctionSOD2 codes for manganese superoxide dismutase of the mitochondrial matrix (Longo et al., 1999).
Other PhenotypesDeletion of SOD2 decreases survival in stationary phase (Longo et al., 1996).
