ABCC2/Abcc2: a multispecific transporter with dominant excretory functions.
Drug Metab Rev. 2010 Aug;42(3):402-36., [PMID:20082599]
Abstract [show]
ABCC2/Abcc2 (MRP2/Mrp2) is expressed at major physiological barriers, such as the canalicular membrane of liver cells, kidney proximal tubule epithelial cells, enterocytes of the small and large intestine, and syncytiotrophoblast of the placenta. ABCC2/Abcc2 always localizes in the apical membranes. Although ABCC2/Abcc2 transports a variety of amphiphilic anions that belong to different classes of molecules, such as endogenous compounds (e.g., bilirubin-glucuronides), drugs, toxic chemicals, nutraceuticals, and their conjugates, it displays a preference for phase II conjugates. Phenotypically, the most obvious consequence of mutations in ABCC2 that lead to Dubin-Johnson syndrome is conjugate hyperbilirubinemia. ABCC2/Abcc2 harbors multiple binding sites and displays complex transport kinetics.

107 Moreover, several mutations in the rat Abcc2 were shown to affect substrate specificity (Ito et al., 2001b), with D329N and R588L being the most striking, as these mutations did not significantly modulate the transport of taurolitocholate-sulfate and E3040-glucuronide, whereas these changes inhibited the efflux of DNP-SG and LTC4.
