Recombinant Human Canalicular multispecific organic anion transporter 2 (ABCC3), Truncated

Uniprot Id

O15438

Target Species

Human

Target Name

ABCC3

Target Full Name

ATP-binding cassette sub-family C member 3

Target Function

ATP-dependent transporter of the ATP-binding cassette (ABC) family that bind and hydrolyze ATP to enable active transport of various substrates including many drugs, toxicants and endogenous compound across cell membranes. Transports glucuronide conjugates such as bilirubin diglucuronide, estradiol-17-beta-o-glucuronide and GSH conjugates such as leukotriene C4 (LTC4). Transports also various bile salts (taurocholate, glycocholate, taurochenodeoxycholate-3-sulfate, taurolithocholate- 3-sulfate). Does not contribute substantially to bile salt physiology but provides an alternative route for the export of bile acids and glucuronides from cholestatic hepatocytes. Can confers resistance to various anticancer drugs, methotrexate, tenoposide and etoposide, by decreasing accumulation of these drugs in cells.

Target Subcellular Location

Basolateral cell membrane; Multi-pass membrane protein.

Target Protein Families

ABC transporter superfamily, ABCC family, Conjugate transporter (TC 3.A.1.208) subfamily

Target Tissue Specificity

Mainly expressed in the liver. Also expressed in small intestine, colon, prostate, testis, brain and at a lower level in the kidney.

Target Background

The 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 MRP subfamily which is involved in multi-drug resistance. The specific function of this protein has not yet been determined; however, this protein may play a role in the transport of biliary and intestinal excretion of organic anions. Alternatively spliced variants which encode different protein isoforms have been described; however, not all variants have been fully characterized.
