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

pdi-3Protein disulfide-isomerase. (488 aa)    
Predicted Functional Partners:
crt-1
Calreticulin; Molecular calcium-binding chaperone promoting folding, oligomeric assembly and quality control in the ER via the calreticulin/calnexin cycle (By similarity). This lectin may interact transiently with almost all of the monoglucosylated glycoproteins that are synthesized in the ER (By similarity). Probably by controlling the folding of extracellular matrix protein unc-52/Perlecan, may play a role in the formation of fibrous organelles, a hemidesmosome-like structure attaching muscles to the epidermis. Protects dopaminergic neurons against oxidative stress-induced neurodegen [...]

cnx-1
Calnexin; Calcium-binding protein that interacts with newly synthesized glycoproteins in the endoplasmic reticulum. It may act in assisting protein assembly and/or in the retention within the ER of unassembled protein subunits. It seems to play a major role in the quality control apparatus of the ER by the retention of incorrectly folded proteins (By similarity). Required for embryogenesis and larval development under heat and ER stress conditions. May be important for germ cell development. Involved in neuronal necrotic cell death.
   
 0.888
hsp-3
Heat shock 70 kDa protein C; Probably plays a role in facilitating the assembly of multimeric protein complexes inside the ER.
  
 
 0.840
hsp-4
Endoplasmic reticulum chaperone BiP homolog; Endoplasmic reticulum chaperone that plays a key role in protein folding and quality control in the endoplasmic reticulum lumen (By similarity). Required for ER dynamics during the first embryonic cell divisions. Specifically, controls ER transition into sheet-like structures at the onset of mitosis, possibly by regulating homotypic membrane fusion. Belongs to the heat shock protein 70 family.
  
 
 0.804
trx-4
Thioredoxin; Belongs to the thioredoxin family.
  
 
 0.767
dpy-18
Prolyl 4-hydroxylase subunit alpha-1; Catalyzes the post-translational formation of 4- hydroxyproline in -Xaa-Pro-Gly- sequences in collagens and other proteins; Belongs to the P4HA family.
   
 
 0.764
phy-2
Prolyl 4-hydroxylase subunit alpha-2; Catalyzes the post-translational formation of 4- hydroxyproline in -Xaa-Pro-Gly- sequences in collagens and other proteins; Belongs to the P4HA family.
   
 
 0.750
pdi-6
Protein disulfide-isomerase A6 homolog; May function as a chaperone that inhibits aggregation of misfolded proteins (By similarity). May negatively regulate the unfolded protein response (UPR) through binding to UPR sensors ; Belongs to the protein disulfide isomerase family.
