The human ATP dependent efflux transporter BSEP (Bile Salt Export Pump) is the major canalicular bile salt export pump responsible for active transport of bile salts across the hepatocyte canalicular membrane into bile. Mutations in the BSEP gene are associated with cholestatic liver diseases of varying severity, but also BSEP inhibition by a drug or its metabolites can lead to cholestasis and drug-induced liver injury (DILI).
