The ABC transporter ABCB4 is a phosphatidylcholine translocator expressed at the bile canalicular membrane of hepatocytes. Variations of the ABCB4 gene have been recognized as causing progressive familial intrahepatic cholestasis type 3 (PFIC3) in children, a rare lethal disorder which progresses to cirrhosis and liver failure before adulthood. We studied the effect of the I541F mutation described in a PFIC3 patient. In contrast to wild-type ABCB4 which was localized at the bile canalicular membrane in HepG2 cells and at the apical surface in MDCK cells after stable transfection, the I541F mutant did not fold properly and accumulated in the endoplasmic reticulum (ER). After shifting cells to 27°C, the mutant was expressed at the apical cell...
