Identification of a Nonconserved Amino Acid Residue in Multidrug Resistance Protein 1 Important for Determining Substrate Specificity

1 Sept 2001

Abstract excerpt

Murine multidrug resistance protein 1 (mrp1), differs from its human ortholog (MRP1) in that it fails to confer anthracycline resistance and transports the MRP1 substrate, 17beta-estradiol 17-(beta-d-glucuronide) (E(2)17betaG), very poorly. By mutating variant residues in mrp1 to those present in MRP1, we identified Glu(1089) of MRP1 as being critical for anthracycline resistance. However, Glu(1089) mutations had...
