OrganismSaccharomyces cerevisiae (replicative)
Aging PhenotypeShortened life-span
Allele TypeDeletion
DescriptionDeletion of Cu-Zn superoxide dismutase decreases replicative life-span by approximately 40% (Wawryn et al., 2002). The magnitude of the decrease in life-span does not appear to be dependent on oxygen concentration in the atmosphere.
Gene FunctionCytosolic copper-zinc superoxide dismutase.
Other PhenotypesDeletion of SOD1 shortens chronological life-span as well as replicative life span (Longo et al., 1999). Overexpression of SOD1 has no effect on replicative life-span (Kirchman et al., 1999).
