1 The present study examined how the multidrug resistance protein (MRP1), which is an ATP-dependent anionic conjugate transporter, also mediates the transport of reduced glutathione (GSH) and the co-transport of the cationic drug, daunorubicin, with GSH in living GLC4/Adr cells. Daunorubicin ATP binding cassette subfamily C member 1 Homo sapiens
2 We investigated the GSH concentration dependence of the MRP1-mediated ATP-dependent transport of daunorubicin under conditions where the transport of daunorubicin became saturated. Daunorubicin ATP binding cassette subfamily C member 1 Homo sapiens
3 We investigated the GSH concentration dependence of the MRP1-mediated ATP-dependent transport of daunorubicin under conditions where the transport of daunorubicin became saturated. Daunorubicin ATP binding cassette subfamily C member 1 Homo sapiens
4 We were therefore in the situation where GSH acted as an activator: its presence was necessary for the binding and transport of daunorubicin by MRP1. Daunorubicin ATP binding cassette subfamily C member 1 Homo sapiens
