Organic Anion Transporter 3, Rat (OAT3) (Control Peptide)
Description
Highly purified. Control Peptide for O3003-20 and O3003-21. No significant sequence homology is detected with other OATs or other proteins. 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-indep
