The same group also demonstrates the necessity of homodimerization for the BCRP function when using a dominant-negative mutation of BCRP with a L554P alteration in the fifth transmembrane domain (Kage et al., 2002). Login to comment

The BCRP-mediated efflux of MTX in our Caco-2 cells indicated that the BCRP expressed on Caco-2 cells might be the wild type because R482T and R482G mutation were unable to transport MTX to any extent (Chen et al., 2003). Login to comment

The conclusion is further demonstrated by the efflux of rhodamine 123, to which BCRP-conferred resistance is observed in the R482T or R482G mutation but not the wild-type expressed cell lines (Allen et al., 2002a). Login to comment
