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

dnaKMolecular chaperone DnaK; Acts as a chaperone; Belongs to the heat shock protein 70 family. (647 aa)    
Predicted Functional Partners:
dnaJ
Molecular chaperone DnaJ; 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, [...]

grpE
Molecular chaperone 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 [...]

AHF02789.1
Molecular chaperone DnaJ; Derived by automated computational analysis using gene prediction method: Protein Homology.
  
 0.957
groS
Molecular chaperone GroES; Binds to Cpn60 in the presence of Mg-ATP and suppresses the ATPase activity of the latter.
 
 
 0.926
clpB
Protein disaggregation chaperone; Part of a stress-induced multi-chaperone system, it is involved in the recovery of the cell from heat-induced damage, in cooperation with DnaK, DnaJ and GrpE; Belongs to the ClpA/ClpB family.
  
 
 0.926
clpA
ATP-dependent Clp protease ATP-binding protein; ATPase and specificity subunit of the ClpA-ClpP ATP dependent serine protease; directs protease to specific substrates; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the ClpA/ClpB family.
  
 
 0.926
hrcA
HrcA family transcriptional regulator; Negative regulator of class I heat shock genes (grpE-dnaK- dnaJ and groELS operons). Prevents heat-shock induction of these operons.
