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

spoIIAAStage II sporulation protein AA, anti-sigma F factor antagonist; Belongs to the anti-sigma-factor antagonist family. (114 aa)    
Predicted Functional Partners:
spoIIAB
Stage II sporulation protein AB; 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.
 
 
 0.995
sigF
DNA-directed RNA polymerase sigma factor sigma-F; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released.
 
  
 0.980
rsbW
Anti-sigma B factor; 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).
 
 
 0.948
spoIIGA
Sporulation sigma-E factor processing peptidase; 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.
  
  
 0.831
sigB
DNA-directed RNA polymerase general stress sigma factor sigma-B; Belongs to the sigma-70 factor family.
 
  
 0.812
spoIIE
Serine phosphatase stage II sporulation protein E.
  
  
 0.790
spoIIR
Stage II sporulation protein R.
  
   
 0.767
ABC1797
Stage V sporulation protein AD.
 
   
 0.738
ABC1796
Stage V sporulation protein AC.
 
   
 0.721
ABC1798
Stage V sporulation protein AE.
