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

hspDSmall heat shock protein; Observed by proteomics; Citation: Proteomics from VerBerkmoes et al. (2003) unpublished; Belongs to the small heat shock protein (HSP20) family. (158 aa)    
Predicted Functional Partners:
grpE
Possible heat shock protein (HSP-70 COFACTOR), 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 c [...]

hrcA
Transcriptional repressor of class I heat shock genes; Negative regulator of class I heat shock genes (grpE-dnaK- dnaJ and groELS operons). Prevents heat-shock induction of these operons.
  
  
 0.783
clpA
Endopeptidase Clp: ATP-binding chain A; Observed by proteomics; Citation: Proteomics from VerBerkmoes et al. (2003) unpublished; Belongs to the ClpA/ClpB family.
  
 
 0.777
clpB
Endopeptidase Clp: ATP-binding subunit B, clpB; 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. Acts before DnaK, in the processing of protein aggregates. Protein binding stimulates the ATPase activity; ATP hydrolysis unfolds the denatured protein aggregates, which probably helps expose new hydrophobic binding sites on the surface of ClpB-bound aggregates, contributing to the solubilization and refolding of denatured protein aggregates by DnaK (By similarity). Belongs to the C [...]

RPA2895
Possible small heat shock protein; Belongs to the small heat shock protein (HSP20) family.
  
  
 0.741
dnaK
Heat shock protein DnaK (70); Acts as a chaperone; Belongs to the heat shock protein 70 family.
  
 
 0.698
rpoH
RNA polymerase sigma 32 subunit, RpoH, stress response 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.
  
  
 0.691
RPA0888
Putative lysophospholipase L2; Observed by proteomics; Citation: Proteomics from VerBerkmoes et al. (2003) unpublished.
 
     0.665
hslV
Heat shock protein HslV, proteasome-related peptidase subunit; Protease subunit of a proteasome-like degradation complex believed to be a general protein degrading machinery.
   
  
 0.663
hslU
Heat shock protein HslU, proteasome-related ATPase subunit; ATPase subunit of a proteasome-like degradation complex; this subunit has chaperone activity. The binding of ATP and its subsequent hydrolysis by HslU are essential for unfolding of protein substrates subsequently hydrolyzed by HslV. HslU recognizes the N-terminal part of its protein substrates and unfolds these before they are guided to HslV for hydrolysis.
