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

PCSK2Proprotein convertase subtilisin/kexin type 2; Belongs to the peptidase S8 family. (638 aa)    
Predicted Functional Partners:
SCG5
Neuroendocrine protein 7B2; Acts as a molecular chaperone for PCSK2/PC2, preventing its premature activation in the regulated secretory pathway. Binds to inactive PCSK2 in the endoplasmic reticulum and facilitates its transport from there to later compartments of the secretory pathway where it is proteolytically matured and activated. Also required for cleavage of PCSK2 but does not appear to be involved in its folding. Plays a role in regulating pituitary hormone secretion. The C-terminal peptide inhibits PCSK2 in vitro (By similarity).
   
 
 0.864
INS
Insulin A chain; Insulin decreases blood glucose concentration. It increases cell permeability to monosaccharides, amino acids and fatty acids. It accelerates glycolysis, the pentose phosphate cycle, and glycogen synthesis in liver.
   
 
 0.743
CPE
Carboxypeptidase E; Sorting receptor that directs prohormones to the regulated secretory pathway. Acts also as a prohormone processing enzyme in neuro/endocrine cells, removing dibasic residues from the C-terminal end of peptide hormone precursors after initial endoprotease cleavage.
   
  
 0.634
POMC
Proopiomelanocortin.
     
 0.623
THBD
THBD isoform 1.
   
 0.613
GCG
GCG isoform 1.
   
 
 0.593
RESP18
Regulated endocrine specific protein 18.
   
  
 0.545
PTPRN
Protein tyrosine phosphatase, receptor type, N.
   
  
 0.545
PTPRN2
PTPRN2 isoform 5.
   
  
 0.545
DDX17
DEAD-box helicase 17; Belongs to the DEAD box helicase family.
