Cryo-EM Structure of URAT1 in Complex with Benzbromarone
| ||||||||||||
Structural highlights
FunctionS22AC_RAT Electroneutral antiporter that translocates urate across the apical membrane of proximal tubular cells in exchange for monovalent organic or inorganic anions (PubMed:21074513). Involved in renal reabsorption of urate and helps maintaining blood levels of uric acid (PubMed:21074513). Mediates urate uptake by an exchange with organic anions such as (S)-lactate and nicotinate, and inorganic anion Cl(-) (PubMed:21074513). Other inorganic anions such as Br(-), I(-) and NO3(-) may also act as counteranions that exchange for urate (By similarity). Also mediates orotate tubular uptake coupled with nicotinate efflux and to a lesser extent with lactate efflux, therefore displaying a potential role in orotate renal reabsorption. Orotate transport is Cl(-)-dependent (By similarity).[UniProtKB:Q96S37][1] References
