Mammalian kidney and liver are critical in maintaining physiological ionic environment. Kidney specializes in removing toxins, drugs, and other organic anions from the blood by a process called "renal secretion". Besides kidney, anionic substrates are also transported in other organs, e.g., choroid plexus, eye, airway, and placenta. Several multispecific OATs (OAT1-3, OAT-K1 and OATK2) and OATPs (organic anion transporting polypeptides; oatp1-3), have been cloned and characterized from various tissues. OATPs family of proteins are very similar in sequence and secondary protein structure (up to 12 transmembrane domains with cytoplasmic N- and C-terminus).

Recently OAT3 (rat 536-aa, human 568 aa) has been cloned that is most closely related to OAT1 (~49% identity). Rat OAT3 is expressed in the liver, brain, kidney and eye. OAT3 also mediates Na-independent uptake of several organic anions (PAH, ochratoxin, and estrone sulfate, etc). OAT3 shows 92% homology with mouse Roct (reduced in osteosclerosis transporter), possibly an ortholog of rat OAT3. As compared to OAT1-2, strong expression of OAT3 in brain suggests its role in removing organic anion in the brain.
