NameSUN4
OrganismSaccharomyces cerevisiae (replicative)
Aging PhenotypeShortened life-span
Allele TypeDeletion
StrainBKy1-14c
DescriptionDisruption shortens mean (87.5% of normal), but not maximum, life span. (Austriaco, 1996a).
Gene FunctionInvolved in cell septation (Camougrand et al., 2000)
Other PhenotypesMutation causes failure of daughter cells to completely detach and results in a multibudded morphology. (Camougrand et al., 2000)
