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

ctsRTranscriptional regulator CtsR; Negative regulator of clpC, clpB and clpP transcription by binding directly and specifically to their promoter region. (153 aa)    
Predicted Functional Partners:
mcsB
ATP:guanido phosphotransferase family protein; Catalyzes the specific phosphorylation of arginine residues in proteins; Belongs to the ATP:guanido phosphotransferase family.
 
  
 0.993
SERP0163
UvrB/UvrC domain protein; Identified by match to protein family HMM PF02151.
 
  
 0.986
clpC
ATP-dependent Clp protease, ATP-binding subunit ClpC; Required for growth at high temperatures, probably by acting as a chaperone during heat shock and targeting heat-denatured proteins for degradation by ClpP.
  
  
 0.984
clpB
ATP-dependent Clp protease, ATP-binding subunit 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 [...]
  
  
 0.806
hrcA
Heat-inducible transcription repressor HrcA; Negative regulator of class I heat shock genes (grpE-dnaK- dnaJ and groELS operons). Prevents heat-shock induction of these operons.
   
  
 0.677
fapR
Conserved hypothetical protein; Transcriptional factor involved in regulation of membrane lipid biosynthesis by repressing genes involved in fatty acid and phospholipid metabolism.
  
     0.585
nupC
Nucleoside permease NupC; Identified by similarity to EGAD:30360; match to protein family HMM PF01773.
       0.575
dnaK
dnaK protein; Acts as a chaperone; Belongs to the heat shock protein 70 family.
   
  
 0.535
grpE
Heat shock 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- [...]

SERP0167
PIN domain protein; Identified by similarity to OMNI:SA0573; match to protein family HMM PF01850; match to protein family HMM PF01938.
