General description

Multidrug resistance protein 3 (MDR3) is also known as ATP binding cassette subfamily B member 4. It is expressed in hepatocytes and made up of 1279 amino acids. The gene encoding it is localized on human chromosome 7q21.12 and consists of 27 exons.

Specificity

Reacts with an internal epitope of MDR3. Does not cross-react with human MDR1 P-gp.

Immunogen

MDR3 P-gp (amino acids 629-692) GST fusion protein.

Biochem/physiol Actions

Multidrug resistance protein 3 (MDR3) acts as an ATP-dependent exporter and transfers phospholipids, particularly phosphatidylcholine (PC), into bile. Dysfunctioning of MDR3 leads to excess of bile salts in primary bile and further leads to liver diseases.

Physical form

Supplied in serum-free medium containing 0.7% bovine serum albumin and 0.1% sodium azide.

Genotyping is conclusive for the diagnosis of progressive familial intrahepatic cholestasis type 3 (PFIC3). Here we report a Chinese patient of PFIC3 with compound mutations in the ABCB4 gene. Liver biopsy was performed on a 17-year-old male patient with intrahepatic

The human multidrug resistance protein 3 (MDR3/ABCB4) belongs to the ubiquitous family of ATP-binding cassette (ABC) transporters and is located in the canalicular membrane of hepatocytes. There it flops the phospholipids of the phosphatidylcholine (PC) family from the inner to

Epigenetic silencing through promoter hypermethylation is an important hallmark for the inactivation of tumor-related genes in carcinogenesis. Here we identified the ATP-binding cassette sub-family B member 4 (ABCB4) as a novel epigenetically silenced target gene. We investigated the epigenetic regulation

ABCB4, which is specifically expressed on the canalicular membrane of hepatocytes, exports phosphatidylcholine (PC) into bile. Because SM depletion increases cellular PC content and stimulates PC and cholesterol efflux by ABCA1, a key transporter involved in generation of HDL, we
