Phenotypic Suppression
A genetic interaction is inferred when mutation or over expression of one gene results in suppression of any phenotype (other than lethality/growth defect) associated with mutation or over expression of another gene.
Publication
Alterations in cellular metabolism triggered by URA7 or GLN3 inactivation cause imbalanced dNTP pools and increased mutagenesis.
Eukaryotic DNA replication fidelity relies on the concerted action of DNA polymerase nucleotide selectivity, proofreading activity, and DNA mismatch repair (MMR). Nucleotide selectivity and proofreading are affected by the balance and concentration of deoxyribonucleotide (dNTP) pools, which are strictly regulated by ribonucleotide reductase (RNR). Mutations preventing DNA polymerase proofreading activity or MMR function cause mutator phenotypes and consequently increased cancer ... [more]

- phenotype: metabolism and growth (APO:0000094)
Additional Notes
- Dun1 inactivation partially suppresses the dNTP imbalance in ura7 and gln3 mutants
- deletion of DUN1 almost completely suppressed the CAN1 mutator phenotype in pol3-L612M/ura7, pol2-04/gln3, and pol3-L612M/gln3 double mutants
- deletion of DUN1 in exo1/ura7 double mutant also reduced the CAN1 mutation rate up to exo1 single mutant levels
- genetic complex
