NameSOD2
OrganismSaccharomyces cerevisiae (replicative)
Aging PhenotypeShortened life-span
Allele TypeDeletion
StrainUnknown
DescriptionDeletion of either SOD2 or SOD1 shortens replicative life-span (Wawryn et al., 1999).
Gene FunctionMitochondrial superoxide dismutase.
Other PhenotypesDeletion of SOD2 also shortens and overexpression of SOD2 (in combination with overexpression of SOD1) increases chronological life span (Fabrizio et al., 2003).
