Analysis of amino acid residues in the predicted transmembrane pore influencing transport kinetics of the hepatic drug transporter organic anion transporting polypeptide 1B1 (OATP1B1).

Abstract excerpt

The hepatic uptake transporters OATP1B1 (SLCO1B1) and OATP1B3 (SLCO1B3) mediate the uptake of endogenous metabolites and drugs from blood into hepatocytes. Alterations of transport function are accompanied with variations in drug plasma concentrations and the risk of adverse drug effects. Thus, knowledge on amino acids determining substrate recognition or transport kinetics are important to predict alterations in...
