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

SPINK1Serine protease inhibitor Kazal-type 1; Serine protease inhibitor which exhibits anti-trypsin activity. In the pancreas, protects against trypsin- catalyzed premature activation of zymogens (By similarity). (79 aa)    
Predicted Functional Partners:
PRSS1
Alpha-trypsin chain 1; Has activity against the synthetic substrates Boc-Phe-Ser- Arg-Mec, Boc-Leu-Thr-Arg-Mec, Boc-Gln-Ala-Arg-Mec and Boc-Val-Pro-Arg- Mec. The single-chain form is more active than the two-chain form against all of these substrates; Belongs to the peptidase S1 family.
   
 
 0.999
PRSS2
Trypsin-2; In the ileum, may be involved in defensin processing, including DEFA5; Belongs to the peptidase S1 family.
   
 
 0.956
PRSS58
Serine protease 58; Belongs to the peptidase S1 family.
    
 
 0.947
CTRC
Chymotrypsin-C; Regulates activation and degradation of trypsinogens and procarboxypeptidases by targeting specific cleavage sites within their zymogen precursors. Has chymotrypsin-type protease activity and hypocalcemic activity.
   
 
 0.939
PRSS3
Trypsin-3; Digestive protease that cleaves proteins preferentially after an Arg residue and has proteolytic activity toward Kunitz-type trypsin inhibitors. Belongs to the peptidase S1 family.
   
 
 0.922
SPINK2
Serine peptidase inhibitor Kazal type 2.
      
 0.899
CFTR
Cystic fibrosis transmembrane conductance regulator; Epithelial ion channel that plays an important role in the regulation of epithelial ion and water transport and fluid homeostasis. Mediates the transport of chloride ions across the cell membrane. Channel activity is coupled to ATP hydrolysis. The ion channel is also permeable to HCO(3-); selectivity depends on the extracellular chloride concentration. Exerts its function also by modulating the activity of other ion channels and transporters. Plays an important role in airway fluid homeostasis. Contributes to the regulation of the pH [...]
   
  
 0.888
CTRB2
Chymotrypsinogen B2; Belongs to the peptidase S1 family.
   
 
 0.886
CTRB1
Chymotrypsinogen B1; Belongs to the peptidase S1 family.
   
 
 0.885
TMPRSS15
Enteropeptidase non-catalytic heavy chain; Responsible for initiating activation of pancreatic proteolytic proenzymes (trypsin, chymotrypsin and carboxypeptidase A). It catalyzes the conversion of trypsinogen to trypsin which in turn activates other proenzymes including chymotrypsinogen, procarboxypeptidases, and proelastases.
