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

rsbUIndirect positive regulator of sigma-B activity. (338 aa)    
Predicted Functional Partners:
rsbT
Positive regulator of sigma-B activity.
 
 
 0.983
rsbS
Negative regulator of sigma-B activity.
 
 
 0.982
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).
 
 
 0.979
rsbR
Positive regulator of sigma-B activity.
 
 
 0.959
rsbX
Indirect negative regulator of sigma-B activity.
 
   
 0.935
sigB
DNA-directed RNA polymerase general stress sigma factor sigma-B; Belongs to the sigma-70 factor family.
 
 
 0.932
rsbV
Positive regulator of sigma-B activity; Belongs to the anti-sigma-factor antagonist family.
 
   
 0.899
ABC3461
Anti-anti-sigma regulatory factor.
 
 
 0.783
ABC1981
Conserved hypothetical protein.
 
 
 0.700
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.
