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

PCBD2Pterin-4-alpha-carbinolamine dehydratase 2; Involved in tetrahydrobiopterin biosynthesis. Seems to both prevent the formation of 7-pterins and accelerate the formation of quinonoid-BH2 (By similarity). (130 aa)    
Predicted Functional Partners:
PAH
Phenylalanine-4-hydroxylase; Catalyzes the hydroxylation of L-phenylalanine to L-tyrosine. Belongs to the biopterin-dependent aromatic amino acid hydroxylase family.
  
 
 0.982
TH
Tyrosine 3-monooxygenase; Plays an important role in the physiology of adrenergic neurons.
  
 
 0.979
TPH1
Tryptophan hydroxylase 1; Belongs to the biopterin-dependent aromatic amino acid hydroxylase family.
  
 
 0.977
TPH2
Tryptophan hydroxylase 2.
  
 
 0.977
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.
   
 
 0.962
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.
  
0.959
HNF1A
Hepatocyte nuclear factor 1-alpha; Transcriptional activator that regulates the tissue specific expression of multiple genes, especially in pancreatic islet cells and in liver (By similarity). Binds to the inverted palindrome 5'- GTTAATNATTAAC-3'. Activates the transcription of CYP1A2, CYP2E1 and CYP3A11 (By similarity).
    
 
 0.944
CATSPER3
Cation channel sperm-associated protein 3; Voltage-gated calcium channel that plays a central role in calcium-dependent physiological responses essential for successful fertilization, such as sperm hyperactivation, acrosome reaction and chemotaxis towards the oocyte.
   
  
 0.936
DYRK1B
Dual specificity tyrosine-phosphorylation-regulated kinase 1B; Dual-specificity kinase which possesses both serine/threonine and tyrosine kinase activities. Enhances the transcriptional activity of TCF1/HNF1A and FOXO1. Inhibits epithelial cell migration. Mediates colon carcinoma cell survival in mitogen-poor environments. Inhibits the SHH and WNT1 pathways, thereby enhancing adipogenesis. In addition, promotes expression of the gluconeogenic enzyme glucose-6-phosphatase (G6PC); Belongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family. MNB/DYRK subfamily.
    
 
 0.892
IYD
Iodotyrosine deiodinase 1; Catalyzes the oxidative NADPH-dependent deiodination of monoiodotyrosine (L-MIT) or diiodotyrosine (L-DIT). Acts during the hydrolysis of thyroglobulin to liberate iodide, which can then reenter the hormone- producing pathways. Acts more efficiently on monoiodotyrosine than on diiodotyrosine. Belongs to the nitroreductase family.
