Abstract
The cDNA coding for a renal p-aminohippurate (PAH) transporter from winter flounder (Pseudopleuronectes americanus), designated fROAT, was cloned by functional expression in Xenopus laevis oocytes. fROAT is approximately 2.8 kbp in length and encodes a protein of 562 amino acids, related to the rat renal organic anion transporter ROAT1/OAT1 and the organic cation transporters OCT1 and OCT2. In oocytes, fROAT mediated probenecid-sensitive PAH uptake, with a Km for PAH of about 20 microM, and inhibited by external glutarate (GA) (1 mM). The functional characteristics suggest that fROAT is the basolateral PAH/dicarboxylate exchanger of the flounder kidney.Entities:
