PREY

MRS4

L000001180, YKR052C
Iron transporter of the mitochondrial carrier family; mediates Fe2+ transport across the inner mitochondrial membrane; active under low-iron conditions; may transport other cations; protein abundance increases in response to DNA replication stress; MRS4 has a paralog, MRS3, 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.

Dre2, a conserved eukaryotic Fe/S cluster protein, functions in cytosolic Fe/S protein biogenesis.

In a forward genetic screen for interaction with mitochondrial iron carrier proteins in Saccharomyces cerevisiae, a hypomorphic mutation of the essential DRE2 gene was found to confer lethality when combined with Delta mrs3 and Delta mrs4. The dre2 mutant or Dre2-depleted cells were deficient in cytosolic Fe/S cluster protein activities while maintaining mitochondrial Fe/S clusters. The Dre2 amino acid sequence ... [more]
