TTD Target ID: TTDS00430

Target Information
NameEquilibrative nucleoside transporter 1    
Type of targetSuccessful target    
Equilibrative NBMPR-sensitive nucleoside transporter    
Equilibrative nitrobenzylmercaptopurine riboside-sensitive nucleoside transporter    
Nucleoside transporter 1    
Nucleoside transporter, es-type    
Solute carrier family 29 member 1    
[ICD9: 084   ICD10: B50-B54]
BioChemical ClassTransmembrane protein    
UniProt IDQ99808
FunctionMediates both influx and efflux of nucleosides across the membrane (equilibrative transporter). It is sensitive to low concentrations of the inhibitor nitrobenzylmercaptopurine riboside (nbmpr) and is sodium-independent.
