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.

Publication

The yeast PRS3 gene is required for cell integrity, cell cycle arrest upon nutrient deprivation, ion homeostasis and the proper organization of the actin cytoskeleton.

PRS3 is one of a family of five genes encoding phosphoribosylpyrophosphate synthetase, an enzyme which catalyses the first step in a variety of biosynthetic pathways, including purine and pyrimidine biosynthesis. We report here that prs3Delta mutants have a number of phenotypes that suggest an unexpected role for PRS3 in linking nutrient availability to cell cycle progression, cell integrity and the ...
