Ccc1 levels are decreased in Deltamrs3Deltamrs4 cells, but the activity of the transporter is increased, resulting is reduced cytosolic iron. Overexpression of CCC1 in Deltamrs3Deltamrs4 cells results in a severe growth defect due to decreased cytosolic iron, referred to as the mitochondria-vacuole signaling (MVS) phenotype. Mutants were identified that suppress the MVS growth defect, and FRA1 was identified as a gene that suppresses the MVS phenotype. Overexpression of FRA1 suppresses altered transition metal metabolism in Deltamrs3Deltamrs4 cells, whereas deletion of FRA1 is synthetically lethal with Deltamrs3Deltamrs4. Fra1 binds to Tsa1, which encodes a thioredoxin-dependent peroxidase. Deletion of TSA1 or TRR1 is synthetically lethal in Deltamrs3Deltamrs4 cells, suggesting that Deltamrs3Deltamrs4 cells generate reactive oxygen metabolites. The generation of reactive oxygen metabolites in Deltamrs3Deltamrs4 cells was confirmed by use of the reporter molecule 2',7'-dichlorodihydrofluorescein diacetate. These results suggest that mitochondria-induced oxidant damage is responsible for activating Ccc1 and that Fra1 and Tsa1 can reduce oxidant damage."xsd:string |
