STRINGSTRING
COA3 protein (Saccharomyces cerevisiae) - STRING interaction network
"COA3" - Mitochondrial inner membrane protein that participates in regulation of COX1 translation, Cox1p stabilization, and cytochrome oxidase assembly 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

COA3Mitochondrial inner membrane protein that participates in regulation of COX1 translation, Cox1p stabilization, and cytochrome oxidase assembly; Required for assembly of cytochrome c oxidase (complex IV). With COX14, regulates negatively COX1 translation and is involved in MSS51 association with newly synthesized COX1 (85 aa)    
Predicted Functional Partners:
PET111
Mitochondrial translational activator specific for the COX2 mRNA; located in the mitochondrial inner membrane; Required for translation of the mitochondrial gene for cytochrome c oxidase subunit II (COX2) (800 aa)
           
  0.922
COX2
Subunit II of cytochrome c oxidase, which is the terminal member of the mitochondrial inner membrane electron transport chain; one of three mitochondrially-encoded subunits; Cytochrome c oxidase is the component of the respiratory chain that catalyzes the reduction of oxygen to water. Subunits 1- 3 form the functional core of the enzyme complex. Subunit 2 transfers the electrons from cytochrome c via its binuclear copper A center to the bimetallic center of the catalytic subunit 1 (251 aa)
       
 
  0.861
SHY1
Mitochondrial inner membrane protein required for assembly of cytochrome c oxidase (complex IV); associates with complex IV assembly intermediates and complex III/complex IV supercomplexes; similar to human SURF1 involved in Leigh Syndrome; Required for efficient assembly of cytochrome c oxidase in the mitochondrial inner membrane. Involved in a step that couples MSS51-COX14-dependent regulation of COX1 translation to early steps of cytochrome c oxidase assembly (389 aa)
       
 
  0.831
COX1
Subunit I of cytochrome c oxidase, which is the terminal member of the mitochondrial inner membrane electron transport chain; one of three mitochondrially-encoded subunits; Cytochrome c oxidase is the component of the respiratory chain that catalyzes the reduction of oxygen to water. Subunits 1- 3 form the functional core of the enzyme complex. CO I is the catalytic subunit of the enzyme. Electrons originating in cytochrome c are transferred via the copper A center of subunit 2 and heme A of subunit 1 to the bimetallic center formed by heme A3 and copper B (534 aa)
       
 
  0.830
COX3
Subunit III of cytochrome c oxidase, which is the terminal member of the mitochondrial inner membrane electron transport chain; one of three mitochondrially-encoded subunits; Subunits I, II and III form the functional core of the enzyme complex (269 aa)
       
 
  0.812
MSS51
Specific translational activator for the mitochondrial COX1 mRNA; loosely associated with the matrix face of the mitochondrial inner membrane; influences both COX1 mRNA translation and Cox1p assembly into cytochrome c oxidase; Has a dual role in the assembly of cytochrome oxidase subunit 1 (COX1). It has a regulative function on COX1 synthesis, acting as a translational activator specific for the COX1 mRNA, and it also binds to newly synthesized COX1 protein. Together with COX14, may act as a chaperone that binds efficiently unassembled COX1 and prevents it from unproductive aggregatio [...] (436 aa)
     
 
  0.774
AIM22
Putative lipoate-protein ligase, required along with Lip2 and Lip5 for lipoylation of Lat1p and Kgd2p; similar to E. coli LplA; null mutant displays reduced frequency of mitochondrial genome loss; Catalyzes both the ATP-dependent activation of exogenously supplied lipoate to lipoyl-AMP and the transfer of the activated lipoyl onto the lipoyl domains of lipoate-dependent enzymes (409 aa)
       
 
  0.749
PET494
Mitochondrial translational activator specific for the COX3 mRNA, acts together with Pet54p and Pet122p; located in the mitochondrial inner membrane; Required for the expression of the mitochondrial gene for cytochrome c oxidase subunit III (COX3) (489 aa)
           
  0.726
MRP17
Mitochondrial ribosomal protein of the small subunit; MRP17 exhibits genetic interactions with PET122, encoding a COX3-specific translational activator (131 aa)
     
   
  0.715
MRPL8
Mitochondrial ribosomal protein of the large subunit (238 aa)
     
   
  0.708
