Synthetic Growth Defect
A genetic interaction is inferred when mutations in separate genes, each of which alone causes a minimal phenotype, result in a significant growth defect under a given condition when combined in the same cell.
Publication
Protein phosphatases pph3, ptc2, and ptc3 play redundant roles in DNA double-strand break repair by homologous recombination.
In response to a DNA double-strand break (DSB), cells undergo a transient cell cycle arrest prior to mitosis until the break is repaired. In budding yeast (Saccharomyces cerevisiae), the DNA damage checkpoint is regulated by a signaling cascade of protein kinases, including Mec1 and Rad53. When DSB repair is complete, cells resume cell cycle progression (a process called "recovery") by ... [more]
Throughput
- Low Throughput
Ontology Terms
- phenotype: resistance to chemicals (APO:0000087)
- phenotype: chromosome/plasmid maintenance (APO:0000143)
- phenotype: vegetative growth (APO:0000106)
Additional Notes
- genetic complex
- pph3/ptc2/ptc3 triple mutants show a synergistic sensitivity to DNA damaging agents such as MMS, HU and CPT. These cells also show reduced viability and DNA repair after double strand breaks
