STRINGSTRING
PET54 protein (Saccharomyces cerevisiae) - STRING interaction network
"PET54" - Mitochondrial inner membrane protein 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

PET54Mitochondrial inner membrane protein; binds to the 5’ UTR of the COX3 mRNA to activate its translation together with Pet122p and Pet494p; also binds to the COX1 Group I intron AI5 beta to facilitate exon ligation during splicing; Activator of specific mitochondrial mRNAs. PET54 is involved in the excision of intron aI5-beta from pre-mRNA for cytochrome c oxidase I (COX1) and plays a role in promoting the translation of COX3 (293 aa)    
Predicted Functional Partners:
PET122
Mitochondrial translational activator specific for the COX3 mRNA, acts together with Pet54p and Pet494p; located in the mitochondrial inner membrane; Required for expression of the mitochondrial gene for cytochrome c oxidase subunit 3 (COX3). PET122 seems to work by directly interacting with the small ribosomal subunit to promote translation initiation on the COX3 mRNA (254 aa)
       
 
  0.983
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)
       
 
  0.974
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)
       
 
  0.960
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)
       
 
  0.925
MSS18
Nuclear encoded protein needed for efficient splicing of mitochondrial COX1 aI5beta intron; mss18 mutations block cleavage of 5’ exon - intron junction; phenotype of intronless strain suggests additional functions; Involved in splicing of intron aI5-beta of the mitochondrial COX1 transcript (268 aa)
       
 
  0.907
PET309
Specific translational activator for the COX1 mRNA, also influences stability of intron-containing COX1 primary transcripts; localizes to the mitochondrial inner membrane; contains seven pentatricopeptide repeats (PPRs); Required for initiation of translation of the COX1 coding region. Also involved in the stability of the intron containing transcript of COX1 (965 aa)
       
 
  0.905
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)
       
 
  0.847
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)
       
 
  0.812
CBS2
Mitochondrial translational activator of the COB mRNA; interacts with translating ribosomes, acts on the COB mRNA 5’-untranslated leader; Translational activator of cytochrome b. The cytochrome b (coB) leader RNA may represent the target sequence for CBS1 and/ or CBS2 (389 aa)
           
  0.760
COB
Cytochrome b, mitochondrially encoded subunit of the ubiquinol-cytochrome c reductase complex which includes Cobp, Rip1p, Cyt1p, Cor1p, Qcr2p, Qcr6p, Qcr7p, Qcr8p, Qcr9p, and Qcr10p; Component of the ubiquinol-cytochrome c reductase complex (complex III or cytochrome b-c1 complex), which is part of the mitochondrial respiratory chain that generates an electrochemical potential coupled to ATP synthesis. The complex couples electron transfer from ubiquinol to cytochrome c (385 aa)
