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
Constitutively high dNTP concentration inhibits cell cycle progression and the DNA damage checkpoint in yeast Saccharomyces cerevisiae.
In eukaryotic cells the concentration of dNTP is highest in S phase and lowest in G1 phase and is controlled by ribonucleotide reductase (RNR). RNR activity is eliminated in all eukaryotes in G1 phase by a variety of mechanisms: transcriptional regulation, small inhibitory proteins, and protein degradation. After activation of RNR upon commitment to S phase, dATP feedback inhibition ensures ... [more]
Throughput
- Low Throughput
Ontology Terms
- phenotype: vegetative growth (APO:0000106)
Additional Notes
- Overexpression of wildtype RNR1, which results in moderately elevated [dNTP], results in synthetic sickness with orc2-1 or orc5-1 mutants.
