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

spoIIRStage II sporulation protein R. (209 aa)    
Predicted Functional Partners:
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.
 
   
 0.927
spoIIE
Serine phosphatase stage II sporulation protein E.
  
   
 0.916
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.
  
   
 0.906
spoIIID
Stage III sporulation protein D.
  
   
 0.903
spoIIP
Stage II sporulation protein P; Septal wall dissolution protein.
  
   
 0.897
spo0A
Stage 0 sporulation protein A; 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.
  
   
 0.851
spoIIM
Stage II sporulation protein M; Required for complete septum migration and engulfment of the forespore compartment during sporulation. Required for stabilizing and recruiting of SpoIIP to the septal membrane.
  
   
 0.839
spoIIIAA
Stage III sporulation protein AA.
  
  
 0.822
spoIID
Stage II sporulation protein D.
  
   
 0.818
ABC1675
Stage IV sporulation protein.
  
  
 0.817
