Protein

Equilibrative nucleoside transporter 2

Gene
Slc29a2, Ent2
Organism
Rattus norvegicus (Rat)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at transcript leveli

Functioni

Mediates both influx and efflux of nucleosides across the membrane (equilibrative transporter). It is insensitive (EI) to low concentrations of the inhibitor nitrobenzylmercaptopurine riboside (NBMPR) and is sodium-independent. Specific for nucleosides, but may also transport hypoxanthine. May also play a role in the efflux of inosine and hypoxanthine from muscle cells during the net degradation of purine nucleotides that occurs during strenuous exercise and/or in the reuptake of these purines during the recovery process By similarity.
