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

GchfrGTP cyclohydrolase 1 feedback regulatory protein; Mediates tetrahydrobiopterin inhibition of GTP cyclohydrolase 1. This inhibition is reversed by L-phenylalanine. (84 aa)    
Predicted Functional Partners:
Gch1
GTP cyclohydrolase 1; May positively regulate nitric oxide synthesis in endothelial cells. May be involved in dopamine synthesis (By similarity). May modify pain sensitivity and persistence; Belongs to the GTP cyclohydrolase I family.
   
 0.998
Pts
6-pyruvoyl tetrahydrobiopterin synthase; Involved in the biosynthesis of tetrahydrobiopterin, an essential cofactor of aromatic amino acid hydroxylases. Catalyzes the transformation of 7,8-dihydroneopterin triphosphate into 6-pyruvoyl tetrahydropterin; Belongs to the PTPS family.
   
 
 0.726
Qdpr
Dihydropteridine reductase; The product of this enzyme, tetrahydrobiopterin (BH-4), is an essential cofactor for phenylalanine, tyrosine, and tryptophan hydroxylases; Belongs to the short-chain dehydrogenases/reductases (SDR) family.
   
  
 0.703
Spr
Sepiapterin reductase; Catalyzes the final one or two reductions in tetra- hydrobiopterin biosynthesis to form 5,6,7,8-tetrahydrobiopterin.
   
  
 0.667
Dnajc12
DnaJ homolog subfamily C member 12.
   
  
 0.638
Pcbd2
Pterin-4 alpha-carbinolamine dehydratase 2.
   
  
 0.561
Coa8
Cytochrome c oxidase assembly factor 8; Required for cytochrome c complex (COX) IV assembly and function Protects COX assembly from oxidation-induced degradation, COX being the terminal component of the mitochondrial respiratory chain.
   
  
 0.529
Pcbd1
Pterin-4-alpha-carbinolamine dehydratase; Involved in tetrahydrobiopterin biosynthesis. Seems to both prevent the formation of 7-pterins and accelerate the formation of quinonoid-BH2. Coactivator for HNF1A-dependent transcription. Regulates the dimerization of homeodomain protein HNF1A and enhances its transcriptional activity; Belongs to the pterin-4-alpha-carbinolamine dehydratase family.
   
  
 0.527
Nxf7
Nuclear RNA export factor 7.
      
 0.510
Pah
Phenylalanine-4-hydroxylase; Catalyzes the hydroxylation of L-phenylalanine to L-tyrosine.
   
  
 0.506
