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

Score
clpB3Chaperone protein ClpB; Function of homologous gene experimentally demonstrated in an other organism; factor; Belongs to the ClpA/ClpB family. (809 aa)    
Predicted Functional Partners:
clpP
ATP-dependent Clp protease, proteolytic subunit clpP; Cleaves peptides in various proteins in a process that requires ATP hydrolysis. Has a chymotrypsin-like activity. Plays a major role in the degradation of misfolded proteins. Belongs to the peptidase S14 family.
 
 
 0.951
dnaK
Chaperone protein DnaK; Acts as a chaperone; Belongs to the heat shock protein 70 family.
  
 
 0.943
hscA
Chaperone protein HscA (Hsc66); Function of homologous gene experimentally demonstrated in an other organism; factor; Belongs to the heat shock protein 70 family.
  
 
 0.943
clpS
ATP-dependent Clp protease adapter protein ClpS; Function of strongly homologous gene; regulator; Belongs to the ClpS family.
  
 
 0.879
NIDE2011
Homologs of previously reported genes of unknown function.
 
 
 0.879
grpE
Chaperone protein GrpE; Participates actively in the response to hyperosmotic and heat shock by preventing the aggregation of stress-denatured proteins, in association with DnaK and GrpE. It is the nucleotide exchange factor for DnaK and may function as a thermosensor. 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-d [...]

NIDE2453
Heat shock protein, Hsp20 family; Function of strongly homologous gene; factor; Belongs to the small heat shock protein (HSP20) family.
  
 
 0.759
NIDE3859
Heat shock protein, Hsp20 family; Function of strongly homologous gene; factor; Belongs to the small heat shock protein (HSP20) family.
  
 
 0.759
groS
Chaperonin GroES; Binds to Cpn60 in the presence of Mg-ATP and suppresses the ATPase activity of the latter.
  
 
 0.666
groL
Chaperonin GroEL; Prevents misfolding and promotes the refolding and proper assembly of unfolded polypeptides generated under stress conditions.
