ANTI-ABCB4 (HUMAN)

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.

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.
