Orotate, a nutritional compound typically utilized as an intermediate in pyrimidine synthesis, has been suggested to undergo renal reabsorption. However, the detailed mechanisms involved in the process remain unclear, with only urate transporter 1 (URAT1/SLC22A12) being indicated as a transporter involved in its tubular uptake. As an attempt to identify transporters involved in that to help clarify the mechanisms, we examined a possibility that organic anion transporter 10 (OAT10/SLC22A13), which is present at the brush border membrane in renal tubular epithelial cells, could transport orotate. The operation of human OAT10 for orotate transport was demonstrated indeed and analyzed in detail in Madin-Darby canine kidney II cells introduced with this transporter by stable transfection. Orotate transport by OAT10 was found to be kinetically saturable with a biphasic characteristic and dependent on Cl<sup>-</sup>. These are unique characteristics previously unknown in its operation for the other substrates. Orotate transport by OAT10 was, on the other hand, inhibited by several anionic compounds known as OAT10 inhibitors. Finally, the rat ortholog of OAT10 was found not to be able to transport orotate, indicating animal species differences in that function. Thus, human OAT10 has been demonstrated to operate for orotate transport with unique characteristics. << Less
