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

groESChaperonin small subunit; Binds to Cpn60 in the presence of Mg-ATP and suppresses the ATPase activity of the latter; Belongs to the GroES chaperonin family. (94 aa)    
Predicted Functional Partners:
groEL
Chaperonin large subunit; Prevents misfolding and promotes the refolding and proper assembly of unfolded polypeptides generated under stress conditions.
 
 0.999
grpE
Nucleotide exchange factor for DnaK activity; 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. S [...]

dnaK
Molecular chaperone; Acts as a chaperone; Belongs to the heat shock protein 70 family.
 
 
 0.998
htpG
Class III heat-shock protein (molecular chaperone); Molecular chaperone. Has ATPase activity.
   
 
 0.987
dnaJ
Co-factor of molecular chaperone; 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 betwe [...]

clpE
ATP-dependent Clp protease (class III stress gene); ATPase essential both for efficient CtsR-dependent gene derepression during heat stress and for rerepression. Together with ClpP, degrades the global regulator CtsR after heat shock. Is also involved in disaggregation of heat-denatured proteins. Has thus a role in overall protein quality control in response to heat stress.
  
 
 0.961
hrcA
Transcriptional regulator of heat-shock genes; Negative regulator of class I heat shock genes (grpE-dnaK- dnaJ and groELS operons). Prevents heat-shock induction of these operons.
  
  
 0.950
clpY
Two-component ATP-dependent protease (ATPase and chaperone); ATPase subunit of a proteasome-like degradation complex; this subunit has chaperone activity; Belongs to the ClpX chaperone family. HslU subfamily.
   
  
 0.949
tig
Prolyl isomerase (trigger factor); Involved in protein export. Acts as a chaperone by maintaining the newly synthesized protein in an open conformation. Functions as a peptidyl-prolyl cis-trans isomerase (By similarity). Belongs to the FKBP-type PPIase family. Tig subfamily.
  
  
 0.945
clpP
ATP-dependent Clp protease proteolytic subunit; Cleaves peptides in various proteins in a process that requires ATP hydrolysis. Has a limited peptidase activity in the absence of ATP-binding subunits ClpC, ClpE or ClpX. Has a chymotrypsin-like activity. Plays a major role in the degradation of misfolded proteins (By similarity). ClpXP is involved in the complete degradation of the site-2 clipped anti-sigma-W factor RsiW. This results in the release of SigW and the transcriptional activation of genes under the control of the sigma-W factor. Probably the major protease that degrades prot [...]
