FRE6 protein (Saccharomyces cerevisiae) - STRING interaction network
"FRE6" - Putative ferric reductase with similarity to Fre2p in Saccharomyces cerevisiae
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
some 3D structure is known or predicted
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
protein homology

Gene Fusion
FRE6Putative ferric reductase with similarity to Fre2p; expression induced by low iron levels; Metalloreductase responsible for reducing vacuolar iron and copper prior to transport into the cytosol. Catalyzes the reduction of Fe(3+) to Fe(2+) and Cu(2+) to Cu(+), respectively, which can then be transported by the respective vacuolar efflux systems to the cytosol (712 aa)    
Predicted Functional Partners:
Protein with sequence similarity to iron/copper reductases, involved in iron homeostasis; deletion mutant has iron deficiency/accumulation growth defects; expression increased in the absence of copper-responsive transcription factor Mac1p; Required for the uptake of Fe(3+) ions. May participate in the transport of electrons from cytoplasm to an extracellular substrate (Fe(3+) ion) via FAD and heme intermediates (By similarity). Involved in iron homeostasis (686 aa)
Protein with similarity to iron/copper reductases (FRE1-8), possibly involved in iron homeostasis; may interact with ribosomes; null mutant displays elevated frequency of mitochondrial genome loss; Probable cell surface metalloreductase. May be involved in iron or copper homeostasis (By similarity) (570 aa)
Putative divalent metal ion transporter involved in iron homeostasis; transcriptionally regulated by metal ions; member of the Nramp family of metal transport proteins; Has a role in controlling the cellular iron ion levels. Mobilizes vacuolar stores of iron in conditions of low iron levels (473 aa)
High affinity iron permease involved in the transport of iron across the plasma membrane; forms complex with Fet3p; expression is regulated by iron; Permease for high affinity iron uptake (404 aa)
Multicopper oxidase, integral membrane protein with similarity to Fet3p; may have a role in iron transport; Iron transport multicopper oxidase, which is required for Fe(2+) high affinity uptake. May be required to oxidize Fe(2+) and release it from the transporter. Essential component of copper-dependent iron transport (622 aa)
Ferro-O2-oxidoreductase required for high-affinity iron uptake and involved in mediating resistance to copper ion toxicity, belongs to class of integral membrane multicopper oxidases; Iron transport multicopper ferroxidase required for Fe(2+) ion high affinity uptake. Required to oxidize Fe(2+) and release it from the transporter. Essential component of copper- dependent iron transport (636 aa)
Transporter, member of the ARN family of transporters that specifically recognize siderophore-iron chelates; responsible for uptake of iron bound to ferrirubin, ferrirhodin, and related siderophores; Involved in the transport of siderophore ferrichrome and so has a role in iron homeostasis (627 aa)
Putative low-affinity copper transporter of the vacuolar membrane; mutation confers resistance to toxic copper concentrations, while overexpression confers resistance to copper starvation; Provides bioavailable copper via mobilization of vacuolar copper stores and export to the cytoplasm (189 aa)
Putative high affinity iron transporter involved in transport of intravacuolar stores of iron; forms complex with Fet5p; expression is regulated by iron; proposed to play indirect role in endocytosis; High affinity iron transporter probably involved in transport of intravacuolar stores of iron (465 aa)
Ferrioxamine B transporter, member of the ARN family of transporters that specifically recognize siderophore-iron chelates; transcription is induced during iron deprivation and diauxic shift; potentially phosphorylated by Cdc28p; Involved in the transport of siderophore ferrioxamine B and so has a role in iron homeostasis (628 aa)
