FET3

ferroxidase FET3, L000000610, YMR058W
Ferro-O2-oxidoreductase; multicopper oxidase that oxidizes ferrous (Fe2+) to ferric iron (Fe3+) for subsequent cellular uptake by transmembrane permease Ftr1p; required for high-affinity iron uptake and involved in mediating resistance to copper ion toxicity, belongs to class of integral membrane multicopper oxidases; protein abundance increases in response to DNA replication stress
Saccharomyces cerevisiae (S288c)

Synthetic Rescue

A genetic interaction is inferred when mutations or deletions of one gene rescues the lethality or growth defect of a strain mutated or deleted for another gene.

Ace1 prevents intracellular copper accumulation by regulating Fet3 expression and thereby restricting Aft1 activity.

Gaspar-Cordeiro A, Marques Caetano S, Amaral C, Rodrigues-Pousada C, Pimentel C

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]

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.
