CC -!- FUNCTION: Responsible for the low-affinity transport of potassium into
CC the cell, with the probable concomitant uptake of protons (symport
CC system). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000250}; Multi-pass
CC membrane protein {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the HAK/KUP transporter (TC 2.A.72) family.
CC {ECO:0000305}.
