Characterization of hOAT4 and mOat5 as functional orthologs for renal anion uptake and efflux transport [Metabolism, Transport, and Pharmacogenetics]

APRIL 16, 2024
Organic anions (OA) are compounds including drugs or toxicants that are negatively charged at physiological pH and are typically transported by Organic Anion Transporters (OATs). Human OAT4 (SLC22A11) is expressed in the apical membrane of renal proximal tubules. Although there is no rodent ortholog of hOAT4, rodents express Oat5 (Slc22a19), an anion exchanger that is also localized to the apical membrane of renal proximal tubule cells.
