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.

pnp4bPurine nucleoside phosphorylase; The purine nucleoside phosphorylases catalyze the phosphorolytic breakdown of the N-glycosidic bond in the beta- (deoxy)ribonucleoside molecules, with the formation of the corresponding free purine bases and pentose-1-phosphate. (304 aa)    
Predicted Functional Partners:
aprt
Adenine phosphoribosyltransferase.
  
 
 0.991
ada
Adenosine deaminase; Catalyzes the hydrolytic deamination of adenosine and 2- deoxyadenosine. Plays an important role in purine metabolism and in adenosine homeostasis. Modulates signaling by extracellular adenosine, and so contributes indirectly to cellular signaling events. May act as a positive regulator of T-cell coactivation (By similarity). Belongs to the metallo-dependent hydrolases superfamily. Adenosine and AMP deaminases family.
  
 
 0.987
dck
Deoxycytidine kinase.
     
 0.980
gda
Guanine deaminase; Catalyzes the hydrolytic deamination of guanine, producing xanthine and ammonia; Belongs to the metallo-dependent hydrolases superfamily. ATZ/TRZ family.
  
 
 0.967
naprt
Nicotinate phosphoribosyltransferase; Catalyzes the first step in the biosynthesis of NAD from nicotinic acid, the ATP-dependent synthesis of beta-nicotinate D- ribonucleotide from nicotinate and 5-phospho-D-ribose 1-phosphate. Helps prevent cellular oxidative stress via its role in NAD biosynthesis; Belongs to the NAPRTase family.
    
 0.966
hprt1l
Hypoxanthine phosphoribosyltransferase; Belongs to the purine/pyrimidine phosphoribosyltransferase family.
  
 0.963
nmrk1
Nicotinamide riboside kinase 1.
  
 0.959
mibp2
Muscle-specific beta 1 integrin-binding protein 2.
  
 0.959
dguok
Deoxyguanosine kinase.
     
 0.954
nt5e
5'-nucleotidase, ecto (CD73); Belongs to the 5'-nucleotidase family.
  
 
 0.953
