Dosage Lethality

A genetic interaction is inferred when over expression or increased dosage of one gene causes lethality in a strain that is mutated or deleted for another gene.

Deletions of SKY1 or PTK2 in the Saccharomyces cerevisiae trk1Deltatrk2Delta mutant cells exert dual effect on ion homeostasis.

Erez O, Kahana C

Sky1p and Ptk2p are protein kinases that regulate ion transport across the plasma membrane of Saccharomyces cerevisiae. We show here that deletion of SKY1 or PTK2 in trk1,2Delta cells increase spermine tolerance, implying Trk1,2p independent activity. Unexpectedly, trk1,2Deltasky1Delta and trk1,2Deltaptk2Delta cells display hypersensitivity to LiCl. These cells also show increased tolerance to low pH and improved growth in low K(+), ... [more]
