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

Score
hprTHypoxanthine phosphoribosyltransferase HprT; Belongs to the purine/pyrimidine phosphoribosyltransferase family. (176 aa)    
Predicted Functional Partners:
adk
Adenylate kinase Adk; Catalyzes the reversible transfer of the terminal phosphate group between ATP and AMP. Plays an important role in cellular energy homeostasis and in adenine nucleotide metabolism; Belongs to the adenylate kinase family.
 
  
 0.956
guaA
GMP synthase (glutamine-hydrolysing) GuaA; Catalyzes the synthesis of GMP from XMP.
  
 
 0.950
gmk
Guanylate kinase Gmk; Essential for recycling GMP and indirectly, cGMP.
  
 
 0.946
guaB
Inosine-5-monophosphate dehydrogenase GuaB; Catalyzes the conversion of inosine 5'-phosphate (IMP) to xanthosine 5'-phosphate (XMP), the first committed and rate-limiting step in the de novo synthesis of guanine nucleotides, and therefore plays an important role in the regulation of cell growth. Belongs to the IMPDH/GMPR family.
  
 
 0.946
apt
Adenine phosphoribosyltransferase Apt; Catalyzes a salvage reaction resulting in the formation of AMP, that is energically less costly than de novo synthesis.
  
 0.943
purH
Bifunctional IMP cyclohydrolase/phosphoribosylaminoimidazolecarboxamide formyltransferase PurH.
  
 
 0.938
purA-2
Adenylosuccinate synthetase; Plays an important role in the de novo pathway of purine nucleotide biosynthesis. Catalyzes the first committed step in the biosynthesis of AMP from IMP; Belongs to the adenylosuccinate synthetase family.
  
 
 0.938
purA
Adenylosuccinate synthetase PurA; Plays an important role in the de novo pathway of purine nucleotide biosynthesis. Catalyzes the first committed step in the biosynthesis of AMP from IMP; Belongs to the adenylosuccinate synthetase family.
  
 
 0.923
gsk
Inosine-guanosine kinase Gsk.
   
 
 0.911
deoD
Purine nucleoside phosphorylase DeoD.
     
 0.909
