NameCIT2
OrganismSaccharomyces cerevisiae (replicative)
Aging PhenotypeNo effect on life-span
Allele TypeDeletion
StrainYPK9
DescriptionDeletion of CIT2 has no effect on life-span (Kirchman et al., 1999). CIT2 is not required for the strain specific life-span extension in petite cells. Overexpression of CIT2 has no effect on life-span (Kirchman et al., 1999).
Gene FunctionPeroxisomal citrate synthase.
Other PhenotypesCIT2 is transcribed up to 30-fold higher in petite cells relative to grande cells (Liao et al., 1991).
