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

sigKRNA polymerase sigma-28 factor; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. (237 aa)    
Predicted Functional Partners:
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.
  
   
 0.818
spoIVA
Stage IV sporulation protein A; ATPase. Has a role at an early stage in the morphogenesis of the spore coat.
  
   
 0.817
ARP43406.1
Hypothetical protein.
  
   
 0.774
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.
 
   
 0.771
spoVAC_1
Stage V sporulation protein AC.
  
     0.768
ymxH
Putative protein YmxH.
 
     0.768
SpoVAD
Stage V sporulation protein AD.
  
     0.768
ARP43339.1
Stage V sporulation protein AE.
  
     0.768
spoVAC_2
Stage V sporulation protein AC.
  
     0.767
ARP41073.1
Hypothetical protein.
  
     0.766
