STRINGSTRING
STRING protein interaction network
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:
a 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 to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

MtnCMetallothionein-3; Metallothionein C (MtnC) encodes a member of the Metallothionein family whose transcription is strongly inducible by copper and cadmium ions. Its induction depends on the transcription factor encoded by MTF-1; Belongs to the metallothionein superfamily. Type 5 family. (43 aa)    
Predicted Functional Partners:
MtnE
Metallothionein E (MtnE) encodes one of the five metallothioneins. They are metal-binding polypeptides that coordinate both physiological and xenobiotic metal ions, either for homeostasis or detoxification purposes. The product of MtnE shows the least specificity towards binding metal ions.
      
 0.914
MTF-1
Metal response element-binding Transcription Factor-1 (MTF-1) encodes a zinc finger protein that primarily controls the homeostasis of physiological trace metals, such as zinc and copper, and the detoxification of non-essential, toxic heavy metals, such as cadmium, mercury, and silver. It activates a number of genes in response to heavy metal load but also induces transcription of the copper importer encoded by Ctr1B upon copper depletion. Variations in the DNA binding site can affect its response to a specific metal.
      
 0.838
MtnA
Metallothionein-1; Metallothionein A (MtnA) encodes a member of the Metallothionein family whose transcript level is higher than that of the other four Drosophila metallothioneins. Transcription is strongly induced by copper and cadmium ions and this induction depends on the transcription factor encoded by MTF-1; Belongs to the metallothionein superfamily. Type 5 family.
      
 0.837
Ctr1B
Copper transporter 1B (Ctr1B) encodes a protein that ensures copper uptake in the intestine. Ctr1B transcription is upregulated under conditions of copper depletion via the metal-responsive transcription factor encoded by MTF-1.
   
  
 0.648
ZnT63C
Zinc transporter 63C, isoform F; Zinc transporter 63C (ZnT63C) encodes a plasma membrane resident zinc transporter belonging to the zinc transporter family that is mainly responsible for zinc export from the cell or into organelles. It plays a key role in effluxing zinc from enterocytes into circulation during dietary zinc absorption.
      
 0.616
Zip42C.2
Zinc/iron regulated transporter-related protein 42C.2 (Zip42C.2) encodes a protein involved in zinc detoxification and zinc transmembrane import.
      
 0.572
Zip89B
Zinc/iron regulated transporter-related protein 89B (Zip89B) encodes a protein involved in zinc detoxification and zinc transmembrane import.
      
 0.563
Atox1
Antioxidant 1 copper chaperone (Atox1) null mutants are unable to develop on low-copper food. Furthermore, the intestinal copper importer encoded by Ctr1B, which is regulated by copper demand, fails to be induced upon copper starvation in Atox1 mutant larvae, while intestinal metallothionein is upregulated. This suggests intestinal copper accumulation, combined with insufficient delivery to the rest of the body.
   
  
 0.553
ATP7
ATP7, isoform B; ATP7 (ATP7) encodes a copper transmembrane transporter involved in cuticle pigmentation, copper homeostasis and larval development.
      
 0.553
ZnT77C
Zinc transporter 77C (ZnT77C) encodes a protein involved in zinc detoxification and zinc transmembrane import.
