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

Prg3Proteoglycan 3; Possesses similar cytotoxic and cytostimulatory activities to PRG2/MBP. (222 aa)    
Predicted Functional Partners:
Epx
Eosinophil peroxidase heavy chain; Mediates tyrosine nitration of secondary granule proteins in mature resting eosinophils; Belongs to the peroxidase family. XPO subfamily.
   
  
 0.822
Prg2
Eosinophil granule major basic protein; Cytotoxin and helminthotoxin. MBP also induces non-cytolytic histamine release from basophils. It is involved in antiparasitic defense mechanisms and immune hypersensitivity reactions (By similarity).
  
  
0.781
Pappa
Pappalysin-1; Metalloproteinase which specifically cleaves IGFBP-4 and IGFBP-5, resulting in release of bound IGF. Cleavage of IGFBP-4 is dramatically enhanced by the presence of IGF, whereas cleavage of IGFBP-5 is slightly inhibited by the presence of IGF. Isoform 2 cleaves IGFBP-4 very slowly compared to PAPP-A, but its ability to cleave IGFBP-5 is unaffected.
    
 
 0.667
Ear6
Eosinophil-associated, ribonuclease A family, member 6; Belongs to the pancreatic ribonuclease family.
   
  
 0.536
Pappa2
Pappalysin 2.
