Descriptions
MRP2 (Multidrug resistance-associated protein 2) is an efflux transporter for organic anions, expressed in hepatocyte canalicular membranes. It plays a role in exporting bilirubin glucuronide, a breakdown product of heme. The structural analysis of rat Mrp2 (rMrp2) reveals an autoinhibited state where the regulatory domain (R-domain) is folded within the transmembrane domain cavity, preventing substrate binding and NBD:NBD interface formation. Phosphorylation of the R-domain by intracellular kinases relieves autoinhibition, enhancing rMrp2 transport activity. The drug-bound state of rMrp2 shows two probenecid binding sites, suggesting a dynamic interplay with autoinhibition and providing insights into drug modulation of MRP2 activity.
