NameCYT1
OrganismSaccharomyces cerevisiae (replicative)
Aging PhenotypeNo effect on life-span
Allele TypeDeletion
StrainPSY316
DescriptionDeletion of CYT1 has no effect on life-span, but prevents life-span extension by overexpression of HAP4 (Lin et al., 2002).
Gene FunctionCytochrome c1.
Other PhenotypesCYT1 is required for respiration in yeast.
