Secondary Accession Numbers
  • 7854
  • HMDBP03806
Name Equilibrative nucleoside transporter 1
Synonyms
  1. Equilibrative NBMPR-sensitive nucleoside transporter
  2. Equilibrative nitrobenzylmercaptopurine riboside-sensitive nucleoside transporter
  3. Nucleoside transporter, es-type
  4. Solute carrier family 29 member 1
Gene Name SLC29A1
Protein Type Transporter
Biological Properties
General Function Involved in nucleoside transmembrane transporter activity
Specific Function Mediates both influx and efflux of nucleosides across the membrane (equilibrative transporter). It is sensitive (ES) to low concentrations of the inhibitor nitrobenzylmercaptopurine riboside (NBMPR) and is sodium-independent. It has a higher affinity for adenosine. Inhibited by dipyridamole and dilazep (anticancer chemotherapeutics drugs)
Pathways
  • Azathioprine Action Pathway
  • Gemcitabine Action Pathway
  • Gemcitabine Metabolism Pathway
  • Mercaptopurine Action Pathway
  • Mercaptopurine Metabolism Pathway
  • Thioguanine Action Pathway
