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.

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.
 
  
 0.971
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.
  
  
 0.929
spoIIE
Serine phosphatase.
  
  
 0.918
sigB
RNA polymerase sigma-37 factor (sigma-B); Belongs to the sigma-70 factor family.
 
  
 0.907
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).

sigG
RNA polymerase sporulation-specific sigma factor (sigma-G); Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released.
