STRINGSTRING
ARN1 protein (Saccharomyces cerevisiae) - STRING interaction network
"ARN1" - Transporter, member of the ARN family of transporters that specifically recognize siderophore-iron chelates 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

ARN1Transporter, 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)    
Predicted Functional Partners:
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)
     
   
  0.966
SIT1
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)
     
   
0.936
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)
     
   
  0.922
FIT3
Mannoprotein that is incorporated into the cell wall via a glycosylphosphatidylinositol (GPI) anchor, involved in the retention of siderophore-iron in the cell wall; Involved in the uptake of non-siderophore and siderohpore sources of iron. Has a role in the retention of iron in the cell wall and periplasmic space (204 aa)
     
   
  0.896
TIS11
mRNA-binding protein expressed during iron starvation; binds to a sequence element in the 3’-untranslated regions of specific mRNAs to mediate their degradation; involved in iron homeostasis; Binds to specific AU-rich elements (ARE) in the 3’- untranslated region of target mRNAs and promotes their degradation. In response to iron deficiency, promotes the decay of many mRNAs encoding proteins involved in iron-dependent pathways. Recruits the DHH1 helicase to the SDH4 mRNA and promotes SDH4 mRNA decay. Also destabilizes target mRNA by modulating 3’-end processing, creating extended trans [...] (285 aa)

FIT2
Mannoprotein that is incorporated into the cell wall via a glycosylphosphatidylinositol (GPI) anchor, involved in the retention of siderophore-iron in the cell wall; Involved in the uptake of non-siderophore and siderohpore sources of iron. Has a role in the retention of iron in the cell wall and periplasmic space (153 aa)
     
   
  0.878
FRE1
Ferric reductase and cupric reductase, reduces siderophore-bound iron and oxidized copper prior to uptake by transporters; expression induced by low copper and iron 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 Cu(+) uptake (686 aa)
     
   
  0.797
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)
           
  0.794
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)
     
   
  0.784
FRE2
Ferric 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)
