NameSWI4
OrganismSaccharomyces cerevisiae (replicative)
Aging PhenotypeShortened life-span
Allele TypeDeletion
StrainW303R
DescriptionDeletion of SWI4 shortens life-span by approximately 90% (Kaeberlein and Guarente, 2002). SSD1-V partially suppresses the short life-span of a swi4 mutant.
Gene FunctionSBF transcription factor involved in regulating G1 cyclins and cell wall stability (Nasmyth and Dirick, 1991; Igual et al., 1996).
Other PhenotypesMutation of swi4 results in slow growth and temperature sensitivity, both of which are suppressed by SSD1-V (Kaeberlein and Guarente, 2002).
