NameADA1
OrganismSaccharomyces cerevisiae (replicative)
Aging PhenotypeShortened life-span
Allele TypeDeletion
StrainW303-1A
DescriptionDeletion of ADA1 shortens life-span by approximately 80% (Sinclair et al., 1997). This is not a premature aging phenotype as “old” ADA1 cells do not become prematurely sterile or show other biomarkers of yeast aging (Sinclair et al., 1997; Smeal et al., 1996).
Gene FunctionTranscription factor in ADA complex.
Other PhenotypesADA1 mutants are temperature-sensitive and respiratory-deficient (Marcus et al., 1994).
