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

spoIIAAAnti-anti-sigma factor (antagonist of SpoIIAB); Belongs to the anti-sigma-factor antagonist family. (117 aa)    
Predicted Functional Partners:
spoIIAB
Anti-sigma factor (antagonist of sigma-F) and serine kinase; 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.
 
 
 0.999
sigF
RNA polymerase sporulation-specific sigma factor (sigma-F); Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released.
 
  
 0.955
rsbW
Switch protein/serine kinase and anti-sigma factor (inhibitory sigma-B binding protein); Negative regulator of sigma-B activity. Phosphorylates and inactivates its specific antagonist protein, RsbV. Upon phosphorylation of RsbV, RsbW is released and binds to sigma-B, thereby blocking its ability to form an RNA polymerase holoenzyme (E-sigma-B).
 
 
 0.895
sigB
RNA polymerase sigma-37 factor (sigma-B); Belongs to the sigma-70 factor family.
 
  
 0.873
spoIIGA
Protease 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.
  
  
 0.855
spoVAC
SpoVAC.
 
   
 0.848
spoVAD
SpoVAD.
 
   
 0.846
spoIIR
SpoIIR.
  
   
 0.833
spoIIE
Serine phosphatase.
  
  
 0.781
spoIVA
Sporulation Stage IV protein A SpoIVA; ATPase. Has a role at an early stage in the morphogenesis of the spore coat.
