CC -!- FUNCTION: Proton/glutathione antiporter that imports glutathione from
CC the vacuole and exports it through the plasma membrane. Involved in
CC resistance to oxidative stress and modulation of the PKA pathway.
CC {ECO:0000269|PubMed:21490148}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000269|PubMed:21490148};
CC Multi-pass membrane protein {ECO:0000269|PubMed:21490148}. Vacuole
CC membrane {ECO:0000269|PubMed:21490148}; Multi-pass membrane protein
CC {ECO:0000269|PubMed:21490148}.
CC -!- INDUCTION: By iron depletion. Expressed at a very low level.
CC {ECO:0000269|PubMed:21490148}.
CC -!- SIMILARITY: Belongs to the major facilitator superfamily.
CC {ECO:0000305}.
