193 As shown in Table 2, mutation T1237G, like T1237A, significantly FIGURE 4: ATP-dependent [3H]E217βG uptake by membrane vesicles prepared from HEK293 cells stably transfected with wild-type or mutant MRP3. Panel A: Relative protein expression levels of wild-type and mutant MRP3 proteins in stably transfected HEK293 cells.

212 Thus, the effects of the mutations T1237G, T1237S, and T1237L on the ability of MRP3 to transport these three substrates were also examined by in vitro transport assays (Figure 8B-D).

213 Replacement of Thr1237 with Gly, like mutation T1237A, dramatically increased the ability of MRP3 to transport methotrexate (Figure 8B), E217βG (Figure 8C), and taurocholate (Figure 8D).

278 Although the majority of mutations that eliminated hydrogen-bonding potential had a negative effect on the activity FIGURE 8: Effect of mutations T1237S, T1237L, and T1237G on ATP-dependent [3H]methotrexate (panel B), [3H]E217βG (panel C), and [3H]taurocholate (panel D) uptake by wild-type MRP3.

288 In addition, conversion of polar residue Thr1237 to either Ala or Gly markedly increased the ability to confer VP-16 resistance and to transport E217βG, taurocholate, and methotrexate, while mutation to a bulkier and more hydrophobic Leu residue resulted in only a moderate increase in transport of all three substrates.
