7.6.2.3

Accepted name:

ABC-type glutathione-S-conjugate transporter

Reaction:

ATP + H₂O + glutathione-S-conjugate_{[side 1]} = ADP + phosphate + glutathione-S-conjugate_{[side 2]}

Other name(s):

multidrug resistance-associated protein 1; glutathione-S-conjugate-translocating ATPase; MRP; MRP1; ABCC1 (gene name); YBT1 (gene name); YCF1 (gene name)

Systematic name:

ATP phosphohydrolase (ABC-type, glutathione-S-conjugate-exporting)

Comments:

A eukaryotic ATP-binding cassette (ABC) type transporter that mediates the transport of glutathione-S-conjugates. The mammalian enzyme, which also transports some glucuronides, exports the substrates out of the cell, while plant and fungal transporters export them into the vacuole. Over-expression confers resistance to anticancer drugs by their efficient exportation in glutathione-S-conjugate form.
