Pump for glutathione S-conjugates. Involved in regulation of K(+) and Na(+) cell content. Mediates resistance to NaCl and Li(+), confers sensitivity to sulfonylurea drugs such as glibenclamide (inducer of stomatal opening), and required for stomatal opening regulation by auxin, abscisic acid (ABA) and external Ca(2+). Transports oestradiol-17-(beta-D-glucuronide) (E(2)17G). Involved in the root auxin content regulation that controls the transition from primary root elongation to lateral root formation. Plays a role in ABA-mediated germination inhibition.
Synonyms: ABC transporter ABCC.5, AtABCC5, ATP-energized glutathione S-conjugate pump 5, Glutathione S-conjugate-transporting ATPase 5, Multidrug resistance-associated protein 5
