STRINGSTRING
PET111 protein (Saccharomyces cerevisiae) - STRING interaction network
"PET111" - Mitochondrial translational activator specific for the COX2 mRNA 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

PET111Mitochondrial 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)    
Predicted Functional Partners:
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)
       
 
  0.971
PET54
Mitochondrial 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)
       
 
  0.960
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)
       
 
  0.954
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)
       
 
  0.937
COA3
Mitochondrial 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)
           
  0.922
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)
           
  0.891
MTF2
Mitochondrial matrix protein that interacts with an N-terminal region of mitochondrial RNA polymerase (Rpo41p) and couples RNA processing and translation to transcription; Required for the processing and/or for the stability of the CYTB and COX1 intron-containing pre-mRNAs and of the ATP6 transcript. Could be a stem-loop RNA-binding protein that plays a role in determining RNA stability (440 aa)
       
 
  0.868
MSS2
Peripherally bound inner membrane protein of the mitochondrial matrix involved in membrane insertion of C-terminus of Cox2p, interacts genetically and physically with Cox18p; Required to stabilize mitochondrial cytochrome C oxidase subunit 2 (COX2) and to translocate the C-terminal domain of COX2 through the inner membrane (351 aa)
           
  0.792
COX18
Mitochondrial integral inner membrane protein required for membrane insertion of C-terminus of Cox2p; interacts genetically and physically with Mss2p and Pnt1p; similar to S. cerevisiae Oxa1, N. crassa Oxa2p, and E. coli YidC; Required for the insertion of integral membrane proteins into the mitochondrial inner membrane. Essential for the activity and assembly of cytochrome c oxidase. Plays a central role in the translocation and export of the C-terminal part of the COX2 protein into the mitochondrial intermembrane space (316 aa)
           
  0.791
OXA1
Mitochondrial inner membrane insertase, mediates the insertion of both mitochondrial- and nuclear-encoded proteins from the matrix into the inner membrane, interacts with mitochondrial ribosomes; conserved from bacteria to animals; Mitochondrial inner membrane insertase that mediates the insertion of both mitochondrion-encoded precursors and nuclear- encoded proteins from the matrix into the inner membrane. Links mitoribosomes with the inner membrane (PubMed-22904327). Forms pores capable of accommodating translocating protein segments (PubMed-22829595). Essential for the activity and [...] (402 aa)
