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

Reg4Regenerating islet-derived protein 4; Calcium-independent lectin displaying mannose-binding specificity and able to maintain carbohydrate recognition activity in an acidic environment. May be involved in inflammatory and metaplastic responses of the gastrointestinal epithelium (By similarity). (157 aa)    
Predicted Functional Partners:
Krt20
Keratin, type I cytoskeletal 20; Plays a significant role in maintaining keratin filament organization in intestinal epithelia. When phosphorylated, plays a role in the secretion of mucin in the small intestine (By similarity).
   
 
 0.682
Spink4
Serine peptidase inhibitor, Kazal type 4.
   
  
 0.627
Lgals4
Galectin-4; Galectin that binds lactose and a related range of sugars.
   
 
 0.622
Lgr5
Leucine-rich repeat-containing G-protein coupled receptor 5; Receptor for R-spondins that potentiates the canonical Wnt signaling pathway and acts as a stem cell marker of the intestinal epithelium and the hair follicle. Upon binding to R-spondins (RSPO1, RSPO2, RSPO3 or RSPO4), associates with phosphorylated LRP6 and frizzled receptors that are activated by extracellular Wnt receptors, triggering the canonical Wnt signaling pathway to increase expression of target genes. In contrast to classical G-protein coupled receptors, does not activate heterotrimeric G-proteins to transduce the [...]

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.
   
  
 0.554
Agr2
Anterior gradient 2 (Xenopus laevis) (Predicted), isoform CRA_a.
      
 0.547
Spink8
Similar to Esophagus cancer-related gene-2 protein (ECRG-2) (Predicted), isoform CRA_a.
      
 0.531
Pnoc
Prepronociceptin; [Nociceptin]: Ligand of the opioid receptor-like receptor OPRL1. It may act as a transmitter in the brain by modulating nociceptive and locomotor behavior. May be involved in neuronal differentiation and development. [Orphanin FQ2]: Has potent analgesic activity.
      
 0.508
Tff3
Trefoil factor 3; Involved in the maintenance and repair of the intestinal mucosa. Promotes the mobility of epithelial cells in healing processes (motogen) (By similarity).
   
  
 0.494
Defa6
Defensin alpha 6.
