| Outline of Final Research Achievements |
Organic anion transporter OAT10 was reported to mediate high-affinitiy nicotinate transport as well as low-affinitiy urate transport. Since I noticed that OAT10 may function as a second apical urate transporter URAT2, here I performed the experiments 1) to clarify the precise mechanisms of urate transport via URAT2 and 2) to accumulate the basic information for the new drug development for urate-lowering agents. As a results, I could find that URAT2 has an exchange mode for intracellular organic anions similar to URAT1 and broader substrate recognition to that of URAT1. In addition, I could get the fundamental structural information to raise novel urate-lowering agents.
