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
Genetic interactions between TFIIF and TFIIS.
The eukaryotic transcript elongation factor TFIIS is encoded by a nonessential gene, PPR2, in Saccharomyces cerevisiae. Disruptions of PPR2 are lethal in conjunction with a disruption in the nonessential gene TAF14/TFG3. While investigating which of the Taf14p-containing complexes may be responsible for the synthetic lethality between ppr2Delta and taf14Delta, we discovered genetic interactions between PPR2 and both TFG1 and TFG2 ...
