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
Phosphatase Complex Pph3/Psy2 Is Involved in Regulation of Efficient Non-Homologous End-Joining Pathway in the Yeast Saccharomyces cerevisiae.
One of the main mechanisms for double stranded DNA break (DSB) repair is through the non-homologous end-joining (NHEJ) pathway. Using plasmid and chromosomal repair assays, we showed that deletion mutant strains for interacting proteins Pph3p and Psy2p had reduced efficiencies in NHEJ. We further observed that this activity of Pph3p and Psy2p appeared linked to cell cycle Rad53p and Chk1p ... [more]
Throughput
- High Throughput
Ontology Terms
- phenotype: inviable (APO:0000112)
- phenotype: resistance to chemicals (APO:0000087)
Additional Notes
- when DNA damage was induced, overexpression of either PPH3 or PSY2 formed SDL interactions with gene deletion strains for each of the three members of MRX complex MRE11, RAD50 and XRS2 in a synthetic dosage lethal screen
