Rat Organic Anion Transport Protein 1A1 Interacts Directly With Organic Anion Transport Protein 1A4 Facilitating Its Maturation and Trafficking to the Hepatocyte Plasma Membrane
Pijun Wang, Wen‐Jun Wang, Jo Choi‐Nurvitadhi, Yaniuska Lescaille, John W. Murray, Allan W. Wolkoff – 18 May 2019 – Organic anion transport proteins (OATPs) on the basolateral surface of hepatocytes mediate uptake of a number of drugs and endogenous compounds. Previous studies showed that rat OATP1A1 (rOATP1A1) has a postsynaptic density protein, drosophila disc large tumor suppressor, zonula occludens‐1 protein (PDZ) consensus binding motif at its C‐terminus and binds to PDZ domain containing 1 (PDZK1), which is required for its cell‐surface localization.
