ABCB1 Recombinant Monoclonal Antibody

Uniprot Id

P08183

Target Species

Human

Target Name

ABCB1

Target Full Name

ATP-dependent translocase ABCB1

Target Function

Translocates drugs and phospholipids across the membrane. Catalyzes the flop of phospholipids from the cytoplasmic to the exoplasmic leaflet of the apical membrane. Participates mainly to the flop of phosphatidylcholine, phosphatidylethanolamine, beta-D-glucosylceramides and sphingomyelins. Energy-dependent efflux pump responsible for decreased drug accumulation in multidrug-resistant cells.

Target Involvement

Inflammatory bowel disease 13 (IBD13)

Target Subcellular Location

Cell membrane; Multi-pass membrane protein. Apical cell membrane.

Target Protein Families

ABC transporter superfamily, ABCB family, Multidrug resistance exporter (TC 3.A.1.201) subfamily

Target Tissue Specificity

Expressed in liver, kidney, small intestine and brain.

Target Research Area

Transport

Target Synonyms

Target Background

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. The protein encoded by this gene is an ATP-dependent drug efflux pump for xenobiotic compounds with broad substrate specificity. It is responsible for decreased drug accumulation in multidrug-resistant cells and often mediates the development of resistance to anticancer drugs. This protein also functions as a transporter in the blood-brain barrier. Mutations in this gene are associated with colchicine resistance and Inflammatory bowel disease 13. Alternative splicing and the use of alternative promoters results in multiple transcript variants.
