STRING protein interaction network
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:
a 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 to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

rbpA-2Hypothetical protein; Binds to RNA polymerase (RNAP), stimulating transcription from principal, but not alternative sigma factor promoters. (120 aa)    
Predicted Functional Partners:
rpoZ
DNA-directed RNA polymerase subunit omega; Promotes RNA polymerase assembly. Latches the N- and C- terminal regions of the beta' subunit thereby facilitating its interaction with the beta and alpha subunits.
  
 
   0.995
sigA
RNA polymerase, sigma 70 subunit, RpoD; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is the primary sigma factor during exponential growth.
    
 
 0.991
rpoB
DNA-directed RNA polymerase subunit beta; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
    
 
 0.987
rpoC
DNA-directed RNA polymerase subunit beta; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
    
 
 0.985
ADU49422.1
COGs: COG1329 Transcriptional regulators similar to M. xanthus CarD; InterPro IPR003711; KEGG: kra:Krad_0898 transcriptional regulator, CarD family; PFAM: transcription factor CarD; SPTR: Transcriptional regulator, CarD family; PFAM: CarD-like/TRCF domain.
    
 
 0.972
rpoA
DNA-directed RNA polymerase subunit alpha; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
    
   0.941
ADU48290.1
COGs: COG2378 transcriptional regulator protein; KEGG: kra:Krad_1879 transcriptional regulator-like; SPTR: Transcriptional regulator-like protein.
 
 
 
 0.870
ADU48291.1
Hypothetical protein; COGs: COG2378 transcriptional regulator protein; KEGG: kra:Krad_1880 hypothetical protein; SPTR: Putative uncharacterized protein.
 
 
 
 0.816
whiB-6
Transcription factor WhiB; Acts as a transcriptional regulator. Probably redox- responsive. The apo- but not holo-form probably binds DNA.
    
   0.776
whiB-7
Transcription factor WhiB; Acts as a transcriptional regulator. Probably redox- responsive. The apo- but not holo-form probably binds DNA.
