NameATP2
OrganismSaccharomyces cerevisiae (replicative)
Aging PhenotypeN/A
Allele TypeUnknown
StrainYPK9
DescriptionA temperature sensitive allele of ATP2 causes daughter cells derived from mother cells aged at 36C to have a life-span equal to that of the mother cells (Lai et al., 2002).
Gene FunctionBeta subunit of the mitochondrial F1-F0 ATPase.
Other PhenotypesThe valine to isoleucine mutation at amino acid 90 does not affect growth on non-fermentable carbon sources (Lai et al., 2002). This allele is associated with loss of mitochondrial membrane potential and failure to segregate functional mitochondria to daughter cells.
