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

rpoHRNA polymerase sigma factor; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is involved in regulation of expression of heat shock genes. (284 aa)    
Predicted Functional Partners:
rpoA
DNA-directed RNA polymerase alpha subunit; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
  
 
 0.922
dnaJ
DnaJ protein; Participates actively in the response to hyperosmotic and heat shock by preventing the aggregation of stress-denatured proteins and by disaggregating proteins, also in an autonomous, DnaK-independent fashion. Unfolded proteins bind initially to DnaJ; upon interaction with the DnaJ-bound protein, DnaK hydrolyzes its bound ATP, resulting in the formation of a stable complex. GrpE releases ADP from DnaK; ATP binding to DnaK triggers the release of the substrate protein, thus completing the reaction cycle. Several rounds of ATP-dependent interactions between DnaJ, DnaK and Gr [...]

groEL
60 kDa chaperonin; Prevents misfolding and promotes the refolding and proper assembly of unfolded polypeptides generated under stress conditions.
   
 
 0.885
rpoB
DNA-directed RNA polymerase beta chain; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
  
 
 0.873
rpoC
DNA-directed RNA polymerase beta' subunit; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
  
 
 0.862
dnaK
DnaK protein; Acts as a chaperone; Belongs to the heat shock protein 70 family.
   
 
 0.824
hflB
Cell division protein FtsH; Acts as a processive, ATP-dependent zinc metallopeptidase for both cytoplasmic and membrane proteins. Plays a role in the quality control of integral membrane proteins; In the central section; belongs to the AAA ATPase family.
  
 
 0.754
ftsY
Cell division protein FtsY; Involved in targeting and insertion of nascent membrane proteins into the cytoplasmic membrane. Acts as a receptor for the complex formed by the signal recognition particle (SRP) and the ribosome-nascent chain (RNC). Interaction with SRP-RNC leads to the transfer of the RNC complex to the Sec translocase for insertion into the membrane, the hydrolysis of GTP by both Ffh and FtsY, and the dissociation of the SRP-FtsY complex into the individual components.
   
 
 0.693
pheT
phenylalanyl-tRNA synthetase beta subunit; Belongs to the phenylalanyl-tRNA synthetase beta subunit family. Type 1 subfamily.
  
  
 0.663
dnaG
DNA primase; RNA polymerase that catalyzes the synthesis of short RNA molecules used as primers for DNA polymerase during DNA replication.
 
  
 0.662
