NameTOR1
OrganismSaccharomyces cerevisiae (replicative)
Aging PhenotypeLife-span extension
Allele TypeDeletion
StrainBY4742; PSY316AT
DescriptionDeletion of TOR1 increases replicative life-span by approximately 20% (Kaeberlein et al., 2005). This life-span extension is indepdent of Sir2 and additive with deletion of Fob1. Calorie restriction of tor1 mutants does not further extend life span.
Gene FunctionNutrient- and growth factor-responsive PI3-like kinase.
Other PhenotypesMutation in TOR proteins has been reported to increase life-span in both worms and flies.
