OrganismSaccharomyces cerevisiae (replicative)
Aging PhenotypeShortened life-span
Allele TypeDeletion
StrainDBY747, W303
DescriptionMutation of RAD9 shortens life span by 30% in strain DBY747 (Kennedy et al., 1994) and in strain W303 (McVey et al., 2001).
Gene FunctionRequired for DNA-damage induced arrest in G2 (Weinert and Hartwell, 1988) and G1 (Siede et al., 1993).
Other PhenotypesMutation of RAD9 has no effect on telomeric silencing or length (Longhese et al., 2000).
