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

GKN1Gastrokine-1; Has mitogenic activity and may be involved in maintaining the integrity of the gastric mucosal epithelium. (199 aa)    
Predicted Functional Partners:
CAPN9
Calpain-9; Calcium-regulated non-lysosomal thiol-protease; Belongs to the peptidase C2 family.
   
  
 0.945
LIPF
Lipase F, gastric type.
   
  
 0.760
GKN2
Gastrokine-2; Gastrokine 2.
  
  
0.731
TFF2
Trefoil factor 2; Inhibits gastrointestinal motility and gastric acid secretion. Could function as a structural component of gastric mucus, possibly by stabilizing glycoproteins in the mucus gel through interactions with carbohydrate side chains (By similarity).
   
  
 0.660
ATP4B
Potassium-transporting ATPase subunit beta; Required for stabilization and maturation of the catalytic proton pump alpha subunit and may also involved in cell adhesion and establishing epithelial cell polarity.
   
  
 0.655
CBLIF
Cobalamin binding intrinsic factor; Promotes absorption of the essential vitamin cobalamin (Cbl) in the ileum. After interaction with CUBN, the CBLIF-cobalamin complex is internalized via receptor-mediated endocytosis; Belongs to the eukaryotic cobalamin transport proteins family.
   
  
 0.654
MUC6
Mucin-6; May provide a mechanism for modulation of the composition of the protective mucus layer related to acid secretion or the presence of bacteria and noxious agents in the lumen. Plays an important role in the cytoprotection of epithelial surfaces and are used as tumor markers in a variety of cancers. May play a role in epithelial organogenesis.
   
  
 0.637
A4GNT
Alpha-1,4-N-acetylglucosaminyltransferase; Catalyzes the transfer of N-acetylglucosamine (GlcNAc) to core 2 branched O-glycans. Necessary for the synthesis of type III mucin which is specifically produced in the stomach, duodenum, and pancreatic duct. May protect against inflammation-associated gastric adenocarcinomas (By similarity).
   
  
 0.550
PGC
Gastricsin; Hydrolyzes a variety of proteins; Belongs to the peptidase A1 family.
   
  
 0.549
ATP4A
Potassium-transporting ATPase alpha chain 1; Catalyzes the hydrolysis of ATP coupled with the exchange of H(+) and K(+) ions across the plasma membrane. Responsible for acid production in the stomach.
   
  
 0.530
