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.

Glutathione (GSH) is an abundant thiol-containing tripeptide that functions in redox homeostasis, protein folding, and iron (Fe) metabolism. In Saccharomyces cerevisiae, GSH depletion leads to increased sensitivity to oxidants and other toxic compounds, disruption of iron-sulfur (Fe-S) cluster biogenesis, and eventually cell death. GSH pools are supplied by intracellular biosynthesis and GSH import from the extracellular environment. Consequently, in GSH-depleted ... [more]
