Predicted to enable ATPase-coupled intramembrane lipid transporter activity; ATPase-coupled transmembrane transporter activity; and xenobiotic transmembrane transporter activity. Involved in bile acid secretion and response to fenofibrate. Located in intercellular canaliculus and plasma membrane. Is expressed in alimentary system and liver. Used to study cholecystitis; cholestasis; hepatocellular carcinoma; intrahepatic cholestasis; and primary sclerosing cholangitis. Human ortholog(s) of this gene implicated in cholestasis (multiple); gallbladder disease; and liver cirrhosis (multiple). Orthologous to human ABCB4 (ATP binding cassette subfamily B member 4).
