The function of ENSG00000124564 (SLC17A3, solute carrier family 17 member 3) is as follows. Mediates the renal excretion of uremic toxin 3-indoxyl sulfate. . [Isoform 2]: Transports organic anions in a voltage-driven, multispecific, manner, on the apical side of renal proximal tubule (PubMed:20810651). In particular, participates in the secretion of urate from the cell into the lumen (PubMed:20810651). Urate is the end product of purine metabolism (PubMed:20810651). May have roles in the metabolism and secretion of estrone sulfate, estradiol-17-beta- glucuronide, ochratoxin A, as wells as drugs such as bumetanide (PubMed:20810651). {ECO:0000269|PubMed:20810651, ECO:0000303|PubMed:20810651}.
