STRINGSTRING
RPO41 protein (Saccharomyces cerevisiae) - STRING interaction network
"RPO41" - Mitochondrial RNA polymerase 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

RPO41Mitochondrial RNA polymerase; single subunit enzyme similar to those of T3 and T7 bacteriophages; requires a specificity subunit encoded by MTF1 for promoter recognition; binding of Mtf1p to the Rpo41p-promoter complex stabilizes the binding and ind /.../NA bending; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates (1351 aa)    
Predicted Functional Partners:
MTF1
Mitochondrial RNA polymerase specificity factor; has structural similarity to S-adenosylmethionine-dependent methyltransferases and functional similarity to bacterial sigma-factors; binding of Mtf1p to the core polymerase (Rpo41p)-promoter complex s /.../zes the binding and induces DNA bending; Mitochondrial transcription factor that confers selective promoter recognition on the core subunit of the yeast mitochondrial RNA polymerase. Interacts with DNA in a non-specific manner (341 aa)
     
  0.996
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)
       
 
  0.916
STU2
Microtubule-associated protein (MAP) of the XMAP215/Dis1 family; regulates microtubule dynamics during spindle orientation and metaphase chromosome alignment; interacts with spindle pole body component Spc72p; May play a role in the attachment, organization, and/or dynamics of microtubule ends at the spindle pole body (888 aa)
       
      0.789
ABF2
Mitochondrial DNA-binding protein involved in mitochondrial DNA replication and recombination, member of HMG1 DNA-binding protein family; activity may be regulated by protein kinase A phosphorylation; Specific binding to the autonomously replicating sequence 1 (ARS1). Interaction with regulatory regions- probably involved in compacting the mitochondrial genome. It might play a positive role in gene expression and replication (183 aa)
           
  0.776
SUV3
ATP-dependent RNA helicase, component of the mitochondrial degradosome along with the RNase Dss1p; the degradosome associates with the ribosome and mediates RNA turnover; also required during splicing of the COX1 AI5_beta intron; Required for intron-independent turnover and processing of mitochondrial RNA. It is a key control element in nuclear- mitochondrial interactions (737 aa)
     
 
  0.725
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)
     
 
  0.715
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)
     
 
  0.715
PET127
Protein with a role in 5’-end processing of mitochondrial RNAs, located in the mitochondrial membrane; Could be a component of the mitochondrial translation system with a role in promoting accuracy of translational initiation (800 aa)
     
 
  0.697
NIF3
Protein of unknown function, similar to Listeria monocytogenes major sigma factor (rpoD gene product); the authentic, non-tagged protein is detected in highly purified mitochondria in high-throughput studies (288 aa)
           
  0.697
ORI5
Dubious open reading frame unlikely to encode a protein, based on available experimental and comparative sequence data (46 aa)
           
  0.697
