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

sigGRNA polymerase sigma-G factor; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. (257 aa)    
Predicted Functional Partners:
NPD11_459
spore_YlmC_YmxH: sporulation, YlmC/YmxH family protein; [S] COG1873 Uncharacterized conserved protein.
 
     0.906
NPD11_462
Sporulation factor SpoIIGA family protein; 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. Belongs to the peptidase U4 family.
 
  
 0.902
spoIIE
spore_II_E: stage II sporulation protein E; [TK] COG2208 Serine phosphatase RsbU, regulator of sigma subunit.
  
  
 0.873
spo0A
Sporulation transcription factor Spo0A; 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.
  
   
 0.866
spoIIAB
Anti-sigma F factor; 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.
  
  
 0.855
spoIVA
Stage IV sporulation protein A; ATPase. Has a role at an early stage in the morphogenesis of the spore coat.
 
  
 0.814
spoIIR
spore_II_R: stage II sporulation protein R.
 
   
 0.812
spoIIID
spore_III_D: sporulation transcriptional regulator SpoIIID.
  
  
 0.806
ytfJ
spore_ytfJ: sporulation protein YtfJ; [S] COG3874 Uncharacterized conserved protein.
  
   
 0.806
spoVT
spore_V_T: stage V sporulation protein T; [K] COG2002 Regulators of stationary/sporulation gene expression.
  
   
 0.795
