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

Gm21987Cytochrome c oxidase copper chaperone; Copper metallochaperone essential for the assembly of the mitochondrial respiratory chain complex IV (CIV), also known as cytochrome c oxidase. Binds two copper ions and delivers them to the metallochaperone SCO1 which transports the copper ions to the Cu(A) site on the cytochrome c oxidase subunit II (MT-CO2/COX2). (63 aa)    
Predicted Functional Partners:
Cox11
Cytochrome c oxidase assembly protein COX11, mitochondrial; Exerts its effect at some terminal stage of cytochrome c oxidase synthesis, probably by being involved in the insertion of the copper B into subunit I.

Chchd4
Mitochondrial intermembrane space import and assembly protein 40; Central component of a redox-sensitive mitochondrial intermembrane space import machinery which is required for the biogenesis of respiratory chain complexes. Functions as chaperone and catalyzes the formation of disulfide bonds in substrate proteins, such as COX17, COX19, MICU1 and COA7. Required for the import and folding of small cysteine-containing proteins (small Tim) in the mitochondrial intermembrane space (IMS). Required for the import of COA7 in the IMS. Precursor proteins to be imported into the IMS are translo [...]

Atox1
Copper transport protein ATOX1; Binds and deliver cytosolic copper to the copper ATPase proteins. May be important in cellular antioxidant defense (By similarity); Belongs to the ATX1 family.
   
 
 0.921
Sco2
Protein SCO2 homolog, mitochondrial; Copper metallochaperone essential for the synthesis and maturation of cytochrome c oxidase subunit II (MT-CO2/COX2). Involved in transporting copper to the Cu(A) site on MT-CO2/COX2. Also acts as a thiol-disulfide oxidoreductase to regulate the redox state of the cysteines in SCO1 during maturation of MT-CO2/COX2. Belongs to the SCO1/2 family.
    
 
 0.893
Ccs
Copper chaperone for superoxide dismutase; Delivers copper to copper zinc superoxide dismutase (SOD1).
    
 
 0.848
Atp7b
Copper-transporting ATPase 2; Copper ion transmembrane transporter involved in the export of copper out of the cells, such as the efflux of hepatic copper into the bile.
      
 0.847
Slc31a1
High affinity copper uptake protein 1; High-affinity, saturable copper transporter involved in dietary copper uptake.
   
  
 0.817
Cox19
Cytochrome c oxidase assembly protein COX19; Required for the transduction of an SCO1-dependent redox signal from the mitochondrion to ATP7A to regulate cellular copper homeostasis. May be required for the assembly of mitochondrial cytochrome c oxidase.
      
 0.801
Atp7a
Copper-transporting ATPase 1; May supply copper to copper-requiring proteins within the secretory pathway, when localized in the trans-Golgi network. Under conditions of elevated extracellular copper, it relocalized to the plasma membrane where it functions in the efflux of copper from cells (By similarity); Belongs to the cation transport ATPase (P-type) (TC 3.A.3) family. Type IB subfamily.
      
 0.798
Coa5
Cytochrome c oxidase assembly factor 5; Involved in an early step of the mitochondrial complex IV assembly process.
