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.


TFIID and Spt-Ada-Gcn5-acetyltransferase functions probed by genome-wide synthetic genetic array analysis using a Saccharomyces cerevisiae taf9-ts allele.

Milgrom E, West RW, Gao C, Shen WC

TAF9 is a TATA-binding protein associated factor (TAF) conserved from yeast to humans and shared by two transcription coactivator complexes, TFIID and SAGA. The essentiality of the TAFs has made it difficult to ascertain their roles in TFIID and SAGA function. Here we performed a genomic synthetic genetic array analysis using a temperature-sensitive allele of TAF9 as a query. Results ... [more]

  • High Throughput|Low Throughput

Ontology Terms

  • phenotype: inviable (APO:0000112)

Additional Notes

  • Genetic interactions were scored as strong when growth defects were observed at both 30 and 34 degrees Celsius, and scored as conditional (heat sensitivity) when growth defects were observed at 34 degrees, but not at 30 degrees.
  • High Throughput: SGA analysis was performed with a temperature-sensitive taf9-ts2 allele as the query.
  • Low Throughput: Genetic interactions identified using an SGA screen were subsequently confirmed by tetrad analysis.
