BAIT
YFH1
L000003525, YDL120W
Mitochondrial matrix iron chaperone; oxidizes and stores iron; interacts with Isu1p to promote Fe-S cluster assembly; mutation results in multiple Fe/S-dependent enzyme deficiencies; human frataxin homolog is mutated in Friedrich's ataxia

PREY
CIT2
citrate (Si)-synthase CIT2, L000000342, YCR005C
Citrate synthase; catalyzes the condensation of acetyl coenzyme A and oxaloacetate to form citrate, peroxisomal isozyme involved in glyoxylate cycle; expression is controlled by Rtg1p and Rtg2p transcription factors; CIT2 has a paralog, CIT1, that arose from the whole genome duplication

Dosage Lethality
A genetic interaction is inferred when over expression or increased dosage of one gene causes lethality in a strain that is mutated or deleted for another gene.

Genetic analysis of iron citrate toxicity in yeast: implications for mammalian iron homeostasis.
Deletion of the yeast homologue of frataxin, YFH1, results in mitochondrial iron accumulation and respiratory deficiency (petite formation). We used a genetic screen to identify mutants that modify iron-associated defects in respiratory activity in Deltayfh1 cells. A deletion in the peroxisomal citrate synthase CIT2 in Deltayfh1 cells decreased the rate of petite formation. Conversely, overexpression of CIT2 in Deltayfh1 cells ... [more]
