Equilibrative nucleobase transporter 1 (Protein FOAP-13) (Solute carrier family 43 member 3)

Sodium-independent purine-selective nucleobase transporter which mediates the equilibrative transport of extracellular purine nucleobases such as adenine, guanine and hypoxanthine (PubMed:26455426, PubMed:32339528). May regulate fatty acid (FA) transport in adipocytes, acting as a positive regulator of FA efflux and as a negative regulator of FA uptake (By similarity). {ECO:0000250|UniProtKB:A2AVZ9, ECO:0000269|PubMed:26455426, ECO:0000269|PubMed:32339528}.; [Isoform 1]: Sodium-independent purine-selective nucleobase transporter which mediates the equilibrative transport of extracellular purine nucleobase adenine (PubMed:30910793). Mediates the influx and efflux of the purine nucleobase analog drug 6-mercaptopurine across the membrane (PubMed:30910793). {ECO:0000269|PubMed:30910793}.; [Isoform 2]: Sodium-independent purine-selective nucleobase transporter which mediates the equilibrative transport of extracellular purine nucleobase adenine (PubMed:30910793). Mediates the influx and efflux of the purine nucleobase analog drug 6-mercaptopurine across the membrane (PubMed:30910793). {ECO:0000269|PubMed:30910793}.
