The function of ENSG00000170482 (SLC23A1, solute carrier family 23 member 1) is as follows. Sodium:ascorbate cotransporter. Mediates electrogenic uptake of vitamin C, with a stoichiometry of 2 Na(+) for each ascorbate (PubMed:10556483, PubMed:10556521, PubMed:10631088, PubMed:36749388). Has retained some ancestral activity toward nucleobases such as urate, an oxidized purine. Low-affinity high-capacity sodium:urate cotransporter, may regulate serum urate levels by serving as a renal urate re-absorber (PubMed:36749388). {ECO:0000269|PubMed:10556483, ECO:0000269|PubMed:10556521, ECO:0000269|PubMed:10631088, ECO:0000269|PubMed:36749388}. [Isoform 2]: Inactive transporter. .
