For E217bG Downloaded from mediated by the multidrug resistance proteins (MRPs). MRP1 uptake, LTM IC50s ranged from 1.2 to 26.9 mMandweremost (ABCC1), MRP2 (ABCC2), MRP3 (ABCC3), and MRP4 (ABCC4) have comparable for MRP1 and MRP4. The LTM rank order inhibitory partially overlapping substrate specificities and all transport 17b- potencies for E217bGversusLTC4 uptake by MRP1, and E217bG estradiol 17-(b-D-glucuronide) (E217bG). The cysteinyl leukotriene versus PGE2 uptake by MRP4, were also similar. Three of four receptor 1 (CysLT1R) antagonist MK-571 inhibits all four MRP CysLT1R-selective LTMs also stimulated MRP2 (but not MRP3) homologs, but little is known about the modulatory effects of newer transport and thus exerted a concentration-dependent biphasic leukotriene modifiers (LTMs).

MRP1 also protects normal resistance proteins (MRPs) (Slot et al., 2011). The four “short” MRPs tissues from xenobiotics when expressed at blood-tissue interfaces have a four-domain structure with two nucleotide binding domains, each (Wijnholds et al., 1998). In addition, MRP1 mediates the efflux of many preceded by a membrane-spanning domain (MSD1/2). The five “long” organic anions, including glutathione (GSH) and glucuronide-conjugated MRPs have an additional NH2-terminally located MSD0. MSD1 and metabolites (Cole, 2014a, b). The physiologic relevance of MRP1 is MSD2 form the pore through which solutes are translocated, powered by associated with its ability to efflux GSH, as well as cysteinyl leukotriene ATP binding and hydrolysis.

MRP3/ABCC3 is most closely related to MRP1, but like MRP2 it has a narrower tissue distribution and substrate specificity. Unlike MRP1 and MRP2, MRP3 does not transport GSH and only poorly transports This work was supported by the Canadian Institutes of Health Research [MOP- LTC and other GSH conjugates although it shares an ability to transport 106513, MOP-133584].

It is also distinct in its ability to efflux prostanoids that, unlike MK-571, one or more of them might also be selective for [e.g., prostaglandin E2 (PGE2)] and cyclic nucleotides (Reid et al., 2003; one of the MRP homologs.

This interest extended to other MRPs as their roles in drug distribution and elimination have been elucidated.
