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

clpP1Clp protease subunit; 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. (196 aa)    
Predicted Functional Partners:
clpB1
ATP-dependent Clp protease, Hsp 100, 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).

clpX
Clp protease ATP-binding subunit, ClpX; ATP-dependent specificity component of the Clp protease. It directs the protease to specific substrates. Can perform chaperone functions in the absence of ClpP.
 
 0.882
clpC
ClpC; Regulatory subunit of ATP-dependent Clp protease; Alternative locus ID: PMED4_12341; Belongs to the ClpA/ClpB family.

dnaK2
Molecular chaperone DnaK2, heat shock protein hsp70-2; Acts as a chaperone; Belongs to the heat shock protein 70 family.
   
 
 0.705
groES
GroES protein (Chaperonin cpn10); Binds to Cpn60 in the presence of Mg-ATP and suppresses the ATPase activity of the latter.
   
 
 0.675
clpS
Conserved hypothetical protein; Involved in the modulation of the specificity of the ClpAP- mediated ATP-dependent protein degradation; Belongs to the ClpS family.
   
 
 0.674
