NameATP2
OrganismSaccharomyces cerevisiae (chronological)
Aging PhenotypeShortened life-span
Allele TypeN/A
StrainDBY746
DescriptionDeletion of ATP2 decreases stationary phase survival (Fabrizio et al., 2003).
Gene FunctionBeta subunit of the mitochondrial F1-F0 ATPase.
Other PhenotypesA temperature sensitive allele of ATP2 causes daughter cells derived from mother cells aged at 36C to have a replicative life-span equal to that of the mother cells (Lai et al., 2002).
