STRINGSTRING
AI2 protein (Saccharomyces cerevisiae) - STRING interaction network
"AI2" - Reverse transcriptase required for splicing of the COX1 pre-mRNA, encoded by a mobile group II intron within the mitochondrial COX1 gene 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

AI2Reverse transcriptase required for splicing of the COX1 pre-mRNA, encoded by a mobile group II intron within the mitochondrial COX1 gene (854 aa)    
Predicted Functional Partners:
BI4
Mitochondrial mRNA maturase, forms a complex with Nam2p to mediate splicing of the bI4 intron of the COB gene; encoded by both exon and intron sequences of partially processed COB mRNA; Mitochondrial mRNA maturase required for splicing of intron 4 of the cytochrome b (COB) gene, containing its own coding sequence, and intron 4 in COX1, coding for the related homing endonuclease aI4. In vivo splicing requires in addition the imported mitochondrial leucyl-tRNA synthetase NAM2. Both proteins seem to stimulate the intrinsic ribozyme activity of intron bI4 through binding to and stabilizing [...] (638 aa)

BI2
Mitochondrial mRNA maturase with a role in splicing, encoded by both exon and intron sequences of partially processed COB mRNA; This protein is responsible for splicing and maturation of cytochrome b mRNA. Specifically, it may be responsible for the splicing specificity of the second intron (423 aa)
     
   
  0.808
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)

BI3
Mitochondrial mRNA maturase, forms a complex with Mrs1p to mediate splicing of the bI3 intron of the COB gene; encoded by both exon and intron sequences of partially processed COB mRNA; Mitochondrial mRNA maturase required for splicing of intron 3 of the cytochrome b (COB) gene, containing its own coding sequence. In vivo splicing requires the formation of a ribonucleoprotein complex together with the imported mitochondrial RNA-splicing protein MRS1. The complex seems to stimulate the intrinsic ribozyme activity of intron bI3 through binding to and stabilizing specific secondary and te [...] (517 aa)

EBS1
Protein involved in inhibition of translation and nonsense-mediated decay; interacts with cap binding protein Cdc33p and with Nam7p; localizes to P-bodies upon glucose starvation; mRNA abundance regulated by mRNA decay factors; Involved in telomere maintenance. May be redundant to EST1, a protein associated with the telomerase (884 aa)
           
  0.697
SLX1
Subunit of a complex, with Slx4p, that hydrolyzes 5’ branches from duplex DNA in response to stalled or converging replication forks; function overlaps with that of Sgs1p-Top3p; Catalytic subunit of the SLX1-SLX4 structure-specific endonuclease that resolves DNA secondary structures generated during DNA repair and recombination. Has endonuclease activity towards branched DNA substrates, introducing single-strand cuts in duplex DNA close to junctions with ss-DNA. Has a preference for simple Y, 5’-flap and replication fork-like structures. It cleaves the strand bearing the 5’-non-homolog [...] (304 aa)

MSS116
DEAD-box protein required for efficient splicing of mitochondrial Group I and II introns; non-polar RNA helicase that also facilities strand annealing; ATP-dependent RNA helicase required for mitochondrial splicing of group I and II introns. Specifically involved in the ATP-dependent splicing of the bl1 intron of COB. Also required for efficient mitochondrial translation (664 aa)
           
  0.623
ATP6
Mitochondrially encoded subunit a of the F0 sector of mitochondrial F1F0 ATP synthase; translation is specifically activated by Atp22p; ATP6 and ATP8 mRNAs are not translated in the absence of the F1 sector of ATPase; Mitochondrial membrane ATP synthase (F(1)F(0) ATP synthase or Complex V) produces ATP from ADP in the presence of a proton gradient across the membrane which is generated by electron transport complexes of the respiratory chain. F-type ATPases consist of two structural domains, F(1) - containing the extramembraneous catalytic core and F(0) - containing the membrane proton [...] (259 aa)

CMR2
Putative protein of unknown function; deletion causes sensitivity to unfolded protein response-inducing agents (1648 aa)

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)
