Invitrogen™ MRP3 Monoclonal Antibody (M3II-21)

Descripción

The antibody reacts with an internal epitope of MRP3, a 190-200 kD transmembrane protein that is closely related to the multidrug resistance protein MRP1. M3II-21 was raised against a bacterial fusion protein of MRP3, containing amino acids 830-949 of the protein. M3II-21 does not cross-react with the human MDR1, MRP1, MRP2 or MRP5 gene products. M3II-21 has potential value for detection of MRP3-mediated drug-resistance in human tumor samples.

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.
