L000001179, YJL133W
Iron transporter, mediates Fe2+ transport across inner mito membrane; mitochondrial carrier family member; active under low-iron conditions; may transport other cations; MRS3 has a paralog, MRS4, that arose from the whole genome duplication

Synthetic Lethality

A genetic interaction is inferred when mutations or deletions in separate genes, each of which alone causes a minimal phenotype, result in lethality when combined in the same cell under a given condition.

Publication

Frataxin and mitochondrial carrier proteins, Mrs3p and Mrs4p, cooperate in providing iron for heme synthesis.

Frataxin is a conserved mitochondrial protein implicated in cellular iron metabolism. Deletion of the yeast frataxin homolog (YFH1) was combined with deletions of MRS3 and MRS4, mitochondrial carrier proteins implicated in iron homeostasis. As previously reported, the Deltayfh1 mutant accumulated iron in mitochondria, whereas the triple mutant (DeltaDeltaDelta) did not. When wild-type, Deltamrs3/4, Deltayfh1, and DeltaDeltaDelta strains were incubated anaerobically, ... [more]
