Dosage Rescue
A genetic interaction is inferred when over expression or increased dosage of one gene rescues the lethality or growth defect of a strain that is mutated or deleted for another gene.
Publication
Telomeric and rDNA silencing in Saccharomyces cerevisiae are dependent on a nuclear NAD(+) salvage pathway.
The Sir2 protein is an NAD(+)-dependent protein deacetylase that is required for silencing at the silent mating-type loci, telomeres, and the ribosomal DNA (rDNA). Mutations in the NAD(+) salvage gene NPT1 weaken all three forms of silencing and also cause a reduction in the intracellular NAD(+) level. We now show that mutation of a highly conserved histidine residue in Npt1p ... [more]
