Description: Rabbit IgG polyclonal antibody for Multidrug resistance protein 3(ABCB4) detection. Tested with WB in Human.
Background: Adenosine triphosphate-binding cassette subfamily B, member 4(ABCB4), also called MDR3, is a protein that in humans is encoded by the ABCB4 gene. MDR1 and MDR3 constitute the human P-glycoprotein gene family. The MDR3 gene contains 28 exons and 27 of these contain coding sequences for the two homologous halves of the protein that correlate with functional domains. MDR3 gene mutations represent a genetic factor involved in this peculiar form of cholesterol gallstone disease in adults.

NCBI Summary for ABCB4
The membrane-associated protein encoded by this gene is a member of the superfamily of ATP-binding cassette (ABC) transporters. ABC proteins transport various molecules across extra- and intra-cellular membranes. ABC genes are divided into seven distinct subfamilies (ABC1, MDR/TAP, MRP, ALD, OABP, GCN20, White). This protein is a member of the MDR/TAP subfamily. Members of the MDR/TAP subfamily are involved in multidrug resistance as well as antigen presentation. This gene encodes a full transporter and member of the p-glycoprotein family of membrane proteins with phosphatidylcholine as its substrate. The function of this protein has not yet been determined; however, it may involve transport of phospholipids from liver hepatocytes into bile. Alternative splicing of this gene results in several products of undetermined function. [provided by RefSeq, Jul 2008]
UniProt Comments for ABCB4
ABCB4: a transporter that mediates ATP-dependent export of organic anions and drugs from the cytoplasm. Hydrolyzes ATP with low efficiency. Human ABCB4 is not capable of conferring drug resistance. Mediates the translocation of phosphatidylcholine across the canalicular membrane of the hepatocyte. Interacts with HAX1. Defects are the cause of gallstones, and progressive familial intrahepatic cholestasis 3, an autosomal recessive liver disorder that progresses to cirrhosis and liver failure before adulthood. Two alternatively spliced human isoforms have been described.
