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

ChgbCCB peptide short form; Secretogranin-1 is a neuroendocrine secretory granule protein, which may be the precursor for other biologically active peptides. (675 aa)    
Predicted Functional Partners:
Chga
p-Glu serpinin precursor; [Pancreastatin]: Strongly inhibits glucose induced insulin release from the pancreas. Serpinin regulates granule biogenesis in endocrine cells by up-regulating the transcription of protease nexin 1 (SERPINE2) via a cAMP-PKA-SP1 pathway. This leads to inhibition of granule protein degradation in the Golgi complex which in turn promotes granule formation (By similarity). Serpinin and pGlu-serpinin can enhance both myocardial contractility (inotropy) and relaxation (lusitropy) and this cardio-stimulation requires a beta 1-adrenergic receptor/adenylate cyclase/cAM [...]

Scg2
Secretogranin-2; Neuroendocrine protein of the granin family that regulates the biogenesis of secretory granules.
   
  
 0.968
Scg3
Secretogranin-3; Member of the granin protein family that regulates the biogenesis of secretory granules. Acts as a sorting receptor for intragranular proteins including chromogranin A/CHGA. May also play a role in angiogenesis. Promotes endothelial proliferation, migration and tube formation through MEK/ERK signaling pathway (By similarity).
   
  
 0.850
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; Belongs to the 7B2 family.
   
  
 0.788
Npy
C-flanking peptide of NPY; NPY is implicated in the control of feeding and in secretion of gonadotrophin-release hormone; Belongs to the NPY family.
      
 0.729
Pcsk1n
proSAAS.
   
  
 0.727
LOC100912228
Neuropeptide Y.
      
 0.724
Vgf
Neuroendocrine regulatory peptide-1; [Neurosecretory protein VGF]: Secreted polyprotein that is packaged and proteolytically processed by prohormone convertases PCSK1 and PCSK2 in a cell-type-specific manner. VGF and peptides derived from its processing play many roles in neurogenesis and neuroplasticity associated with learning, memory, depression and chronic pain (By similarity). [Neuroendocrine regulatory peptide-2]: Plays a role in the control of body fluid homeostasis by regulating vasopressin release. Activates GABAergic interneurons which are inhibitory neurons of the nervous s [...]
   
  
 0.723
Pcsk2
Neuroendocrine convertase 2; Involved in the processing of hormone and other protein precursors at sites comprised of pairs of basic amino acid residues. Responsible for the release of glucagon from proglucagon in pancreatic A cells (By similarity); Belongs to the peptidase S8 family. Furin subfamily.
   
  
 0.696
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.
