STRING protein interaction network
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 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
protein homology

Gene Fusion
ppr2Pentatricopeptide repeat-containing protein 2, mitochondrial; Mitochondrial RNA-binding protein that acts as a general translation factor (432 aa)    
Predicted Functional Partners:
Pentatricopeptide repeat-containing protein 8, mitochondrial; Mitochondrial RNA-binding protein involved in mitochondrial translation. The cox1 mRNA is one target but it is not clear if ppr8 has a single or multiple targets
Pentatricopeptide repeat-containing protein 5, mitochondrial; Mitochondrial RNA-binding protein that acts as a general negative regulator of mitochondrial translation
Pentatricopeptide repeat-containing protein 4, mitochondrial; Mitochondrial RNA-binding protein that specifically activates the translation of the cox1 mRNA
DNA-directed RNA polymerase, mitochondrial; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. Combines in the mitochondrion with mitochondrial transcription factor mtf1 as a holoenzyme to recognize and initiate transcription at the core mitochondrial promoters
Cytochrome c oxidase subunit 2; 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
Cytochrome b; Component of the ubiquinol-cytochrome c reductase complex (complex III or cytochrome b-c1 complex) that is part of the mitochondrial respiratory chain. The b-c1 complex mediates electron transfer from ubiquinol to cytochrome c. Contributes to the generation of a proton gradient across the mitochondrial membrane that is then used for ATP synthesis
Pentatricopeptide repeat-containing protein 7, mitochondrial; Mitochondrial RNA-binding protein required for the stability of the atp6 mRNA
Protein mss51; 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 (By similarity)
THO complex subunit mft1; Component the THO subcomplex of the TREX complex, which operates in coupling transcription elongation to mRNA export. The THO complex is recruited to transcribed genes and moves along the gene with the elongating polymerase during transcription. THO is important for stabilizing nascent RNA in the RNA polymerase II elongation complex by preventing formation of DNA:RNA hybrids behind the elongating polymerase. It functions in cotranscriptional formation of an export-competent messenger ribonucleoprotein particle (mRNP) by facilitating the loading of ATP-dependen [...]
Pentatricopeptide repeat-containing protein 3, mitochondrial; RNA-binding protein involved in the specific removal of group I introns in mitochondrial encoded transcripts. Maintains the stability of the small subunit mitochondrial 15S rRNA and thus the expression of the mitochondrial genome
