OrganismSaccharomyces cerevisiae (chronological)
Aging PhenotypeShortened life-span
Allele TypeDeletion
DescriptionYeast lacking sod1 show a profound defect in entry into and survival during stationary phase (Longo et al., 1996; Longo et al., 1999). This defect is partially suppressed by expression of human Bcl-2 (Longo et al., 1997).
Gene FunctionCytosolic copper-zinc superoxide dismutase.
Other PhenotypesDeletion of sod1 causes sensitivity to hyperoxia as well as methionine and lysine auxotrophies (Longo et al., 1997).
