NameSOD1
OrganismSaccharomyces cerevisiae (replicative)
Aging PhenotypeNo effect on life-span
Allele TypeOverexpression
StrainYPK9
DescriptionOverexpression of SOD1 has no effect on replicative life-span (Kirchman et al., 1999). Deletion of SOD1 shortens replicative life-span (Wawryn et al., 2002).
Gene FunctionCytosolic copper-zinc superoxide dismutase.
Other PhenotypesYeast 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). Deletion of sod1 causes sensitivity to hyperoxia as well as methionine and lysine auxotrophies (Longo et al., 1997).
