STRINGSTRING
FRE2 protein (Saccharomyces cerevisiae) - STRING interaction network
"FRE2" - Ferric reductase and cupric reductase, reduces siderophore-bound iron and oxidized copper prior to uptake by transporters in Saccharomyces cerevisiae
Nodes:
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:
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
Others
textmining
co-expression
protein homology

FRE2Ferric reductase and cupric reductase, reduces siderophore-bound iron and oxidized copper prior to uptake by transporters; expression induced by low iron levels but not by low copper levels; Metalloreductase responsible for reducing extracellular iron and copper prior to import. Catalyzes the reductive uptake of Fe(3+)-salts and Fe(3+) bound to catecholate or hydroxamate siderophores. Fe(3+) is reduced to Fe(2+), which then dissociates from the siderophore and can be imported by the high-affinity Fe(2+) transport complex in the plasma membrane. Also participates in Cu(2+) reduction and [...] (711 aa)    
Predicted Functional Partners:
AFT1
Transcription factor involved in iron utilization and homeostasis; binds the consensus site PyPuCACCCPu and activates the expression of target genes in response to changes in iron availability; Probable transcription factor that activates the genes for FRE1, FRE2 and FET3 in response to iron deprivation. Iron could interact directly with AFT1 and inhibits its activity (690 aa)
       
 
  0.950
FTR1
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)
     
   
  0.939
FET3
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)
     
   
  0.920
FRE8
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)
           
  0.829
FET5
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)
     
   
  0.800
ARN1
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)
     
   
  0.781
CCC2
Cu(+2)-transporting P-type ATPase, required for export of copper from the cytosol into an extracytosolic compartment; has similarity to human proteins involved in Menkes and Wilsons diseases; Probably involved in copper transport and in the regulation of cellular copper level. Retrieves copper from the metallochaperone ATX1 and incorporates it into trans-Golgi vesicles (1004 aa)
           
  0.765
FTH1
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)
     
   
  0.763
FET4
Low-affinity Fe(II) transporter of the plasma membrane; Required for Fe(2+) ion low affinity uptake (552 aa)
           
  0.740
SMF3
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)
