NameHOG1
OrganismSaccharomyces cerevisiae (replicative)
Aging PhenotypeShortened life-span
Allele TypeN/A
StrainPSY316
DescriptionDeletion of HOG1 shortens life span by 25% and prevents life-span extension by high osmolarity (Kaeberlein et al., 2002).
Gene FunctionN/A
Other PhenotypesHOG1 is required for many of the transcriptional responses to high osmolarity, including increased glycerol biosynthesis and MSN2/MSN4-dependent stress response (Rep et al., 2000).
