General annotation (Comments)
| Function | Involved in the ATP-dependent secretion of bile salts into the canaliculus of hepatocytes. |
| Subunit structure | Interacts with HAX1 By similarity. |
| Subcellular location | |
| Tissue specificity | Expressed predominantly, if not exclusively in the liver, where it was further localized to the canalicular microvilli and to subcanalicular vesicles of the hepatocytes by in situ. |
| Domain | Multifunctional polypeptide with two homologous halves, each containing a hydrophobic membrane-anchoring domain and an ATP binding cassette (ABC) domain. |
| Involvement in disease | Cholestasis, progressive familial intrahepatic, 2 (PFIC2) [MIM:601847]: A disorder characterized by early onset of cholestasis that progresses to hepatic fibrosis, cirrhosis, and end-stage liver disease before adulthood. Cholestasis, benign recurrent intrahepatic, 2 (BRIC2) [MIM:605479]: A disorder characterized by intermittent episodes of cholestasis without progression to liver failure. There is initial elevation of serum bile acids, followed by cholestatic jaundice which generally spontaneously resolves after periods of weeks to months. The cholestatic attacks vary in severity and duration. Patients are asymptomatic between episodes, both clinically and biochemically. |
| Sequence similarities | Belongs to the ABC transporter superfamily. ABCB family. Multidrug resistance exporter (TC 3.A.1.201) subfamily. [View classification] Contains 2 ABC transmembrane type-1 domains. Contains 2 ABC transporter domains. |
| Biophysicochemical properties | Kinetic parameters: KM=30.4 µM for taurocholate Ref.13 Vmax=232 pmol/min/mg enzyme for taurocholate transport |
