Synthetic Lethality

A genetic interaction is inferred when mutations or deletions in separate genes, each of which alone causes a minimal phenotype, result in lethality when combined in the same cell under a given condition.

Loss of vacuolar proton-translocating ATPase activity in yeast results in chronic oxidative stress.

Milgrom E, Diab H, Middleton F, Kane PM

Yeast mutants lacking vacuolar proton-translocating ATPase (V-ATPase) subunits (vma mutants) were sensitive to several different oxidants in a recent genomic screen (Thorpe, G. W., Fong, C. S., Alic, N., Higgins, V. J., and Dawes, I. W. (2004) Proc. Natl. Acad. Sci. U. S. A. 101, 6564-6569). We confirmed that mutants lacking a V(1) subunit (vma2Delta), V(o) subunit, or either of ...
