Gene Ontology Molecular Function
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
Ace1 prevents intracellular copper accumulation by regulating Fet3 expression and thereby restricting Aft1 activity.
In the yeast Saccharomyces cerevisiae Aft1, the low iron-sensing transcription factor is known to regulate the expression of the FET3 gene. However, we found that a strain-lacking FET3 is more sensitive to copper excess than a strain-lacking AFT1, and accordingly, FET3 expression is not fully compromised in the latter. These findings suggest that, under such conditions, another regulator comes into ... [more]
Throughput
- Low Throughput
Ontology Terms
- phenotype: chemical compound accumulation (APO:0000095)
Additional Notes
- copper and iron contents in the ace1 strain were dependent on Aft1, as levels dropped in the ace1/aft1 double mutant
