URAT1, a member of the OAT (organic anion transporter) family, is an anion-exchanging uptake transporter localized to the apical (brush border) membrane of renal proximal tubular cells. It is an anion exchanger that selectively reabsorbs uric acid from the proximal tubule in exchange for monovalent anions such as lactate, nicotinoate, acetoacetate, and hydroxybutyrate [2].
