NameYGL014W
OrganismSaccharomyces cerevisiae (replicative)
Aging PhenotypeNo effect on life-span
Allele TypeDeletion
StrainBKy1-14c
DescriptionYgl014p is required for the life span extension by the sir4-42 allele (Kennedy et al., 1997). It should be noted that sir4-42 only extends life span in the BKy1-14c strain which carries a C-terminal truncated allele of UTH4/MPT5 (Kennedy et al., 1997).
Gene FunctionUnknown.
Other PhenotypesA ygl014 mpt5 double deletion strain has increased telomere silencing relative to a mpt5 single mutant (Cockell et al., 1998).
