STRINGSTRING
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

FliA-4DNA-directed RNA polymerase specialized sigma subunit; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. (257 aa)    
Predicted Functional Partners:
RpoB
DNA-directed RNA polymerase, beta subunit/140 kD subunit; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
    
 
 0.908
RsbW
Anti-sigma regulatory factor; Binds to sigma F and blocks its ability to form an RNA polymerase holoenzyme (E-sigma F). Phosphorylates SpoIIAA on a serine residue. This phosphorylation may enable SpoIIAA to act as an anti- anti-sigma factor that counteracts SpoIIAB and thus releases sigma F from inhibition.
 
 
 0.899
PTH_1844
Uncharacterized conserved protein.
 
     0.895
SpoIIAA
Anti-anti-sigma regulatory factor; Antagonist of anti-sigma factor; Belongs to the anti-sigma-factor antagonist family.
 
  
 0.890
RpoD-2
DNA-directed RNA polymerase, sigma subunit.
  
   
 0.886
FlgM
Negative regulator of flagellin synthesis; Anti-sigma28 factor.
  
 
 0.864
PTH_1847
peptidase_U4, Sporulation factor SpoIIGA; Probable aspartic protease that is responsible for the proteolytic cleavage of the RNA polymerase sigma E factor (SigE/spoIIGB) to yield the active peptide in the mother cell during sporulation. Responds to a signal from the forespore that is triggered by the extracellular signal protein SpoIIR. Belongs to the peptidase U4 family.
 
  
 0.847
CitB
Response regulator; May play the central regulatory role in sporulation. It may be an element of the effector pathway responsible for the activation of sporulation genes in response to nutritional stress. Spo0A may act in concert with spo0H (a sigma factor) to control the expression of some genes that are critical to the sporulation process.
  
  
 0.842
RpoC
DNA-directed RNA polymerase, beta' subunit/160 kD subunit; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
    
 
 0.841
PTH_1202
Predicted membrane-associated Zn-dependent protease 1.
  
  
 0.807
