"PCSK1N" - ProSAAS in Homo sapiens
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:
some 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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

PCSK1NProSAAS; May function in the control of the neuroendocrine secretory pathway. Proposed be a specific endogenous inhibitor of PCSK1. ProSAAS and Big PEN-LEN, both containing the C-terminal inhibitory domain, but not the further processed peptides reduce PCSK1 activity in the endoplasmic reticulum and Golgi. It reduces the activity of the 84 kDa form but not the autocatalytically derived 66 kDa form of PCSK1. Subsequent processing of proSAAS may eliminate the inhibition. Slows down convertase-mediated processing of proopiomelanocortin and proenkephalin. May control the intracellular timi [...] (260 aa)    
Predicted Functional Partners:
SAA1
Serum amyloid A-1 protein; Major acute phase protein; Belongs to the SAA family (122 aa)
           
  0.831
PCSK1
Neuroendocrine convertase 1; Involved in the processing of hormone and other protein precursors at sites comprised of pairs of basic amino acid residues. Substrates include POMC, renin, enkephalin, dynorphin, somatostatin, insulin and AGRP; Belongs to the peptidase S8 family. Furin subfamily (753 aa)
     
 
  0.786
CPE
Carboxypeptidase E; Removes residual C-terminal Arg or Lys remaining after initial endoprotease cleavage during prohormone processing. Processes proinsulin; Belongs to the peptidase M14 family (476 aa)
     
   
  0.783
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; Granins (212 aa)
     
   
  0.747
SCG2
Secretogranin-2; Secretogranin-2 is a neuroendocrine secretory granule protein, which is the precursor for biologically active peptides; Granins (617 aa)
     
   
  0.746
CHGB
Secretogranin-1; Secretogranin-1 is a neuroendocrine secretory granule protein, which may be the precursor for other biologically active peptides (677 aa)
     
   
  0.724
SCG3
Secretogranin-3; Secretogranin III; Granins (468 aa)
     
   
  0.702
SAA4
Serum amyloid A-4 protein; Major acute phase reactant. Apolipoprotein of the HDL complex; Belongs to the SAA family (130 aa)
           
  0.688
VGF
Neurosecretory protein VGF; May be involved in the regulation of cell-cell interactions or in synatogenesis during the maturation of the nervous system; Granins (615 aa)
     
   
  0.634
CHGA
Chromogranin-A; Pancreastatin- Strongly inhibits glucose induced insulin release from the pancreas; Belongs to the chromogranin/secretogranin protein family (457 aa)
     
   
  0.608
