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

CalrCalreticulin; Molecular calcium-binding chaperone promoting folding, oligomeric assembly and quality control in the ER via the calreticulin/calnexin cycle. This lectin may interact transiently with almost all of the monoglucosylated glycoproteins that are synthesized in the ER (By similarity). (406 aa)    
Predicted Functional Partners:
Gp93
Glycoprotein 93 (Gp93) encodes a heat shock protein Hsp90 family member that is involved in midgut development.
   
 
 0.997
ERp60
Protein disulfide isomerase activity; peptide disulfide oxidoreductase activity. It is involved in the biological process described with: response to endoplasmic reticulum stress; cell redox homeostasis; protein folding.
   
 0.984
CG2918
EG:25E8.1 protein; It is involved in the biological process described with: multicellular organism reproduction; cellular response to hypoxia; negative regulation of hypoxia-induced intrinsic apoptotic signaling pathway.
   
 
 0.976
Hsc70-3
Endoplasmic reticulum chaperone BiP; Endoplasmic reticulum chaperone that plays a key role in protein folding and quality control in the endoplasmic reticulum lumen. Involved in the correct folding of proteins and degradation of misfolded proteins (By similarity). Acts as a key repressor of the unfolded protein response (UPR) (By similarity).
   
 
 0.975
CaBP1
Protein disulfide-isomerase A6 homolog; Calcium-binding protein 1 (CaBP1) encodes a protein that resides in the lumen of the endoplasmic reticulum. It seems to be relocated outside cells during apoptosis and involved in the phagocytosis of apoptotic cells.
   
 
 0.956
Uggt
UDP-glucose-glycoprotein glucosyltransferase (Uggt) encodes an enzyme that recognizes glycoproteins with folding defects and adds glucose to N-glycans near the misfolded part of the protein. Uggt product is a component of the calnexin cycle and promotes protein folding in the endoplasmic reticulum along with the protein encoded by Cnx99A and Calr; Belongs to the glycosyltransferase 8 family.
   
 
 0.949
Pdi
Protein disulfide-isomerase; Participates in the folding of proteins containing disulfide bonds.
   
 
 0.922
Xbp1
X box binding protein-1 (Xbp1) encodes a transcription factor that mediates the unfolded protein response. Xbp1 mRNA undergoes splicing after being cleaved by the product of Ire1, inducing the expression of ER quality control transcripts. Xbp1 mutants fail to develop beyond the 2nd instar larval stage, indicative of a requirement to resolve inherent ER stress during normal development.
   
  
 0.913
Itpr
Inositol 1,4,5,-trisphosphate receptor (Itpr) encodes an intracellular ligand gated calcium channel. It functions downstream of G-protein coupled receptors that activate Gq/PLCbeta signaling and generate inositol tris-phosphate. Itpr depletion affects ecdysone release, response to nutritional stress, lipid metabolism and flight; Belongs to the InsP3 receptor family.
      
 0.889
Cnx14D
Calnexin 14D; Calcium ion binding; unfolded protein binding. It is involved in the biological process described with: endoplasmic reticulum unfolded protein response; protein folding.
