CC   -!- FUNCTION: Mnh complex is a Na(+)Li(+)/H(+) antiporter involved in Na(+)
CC       and/or Li(+) excretion. Na(+)/H(+) antiport consumes a transmembrane
CC       electrical potential, and is thus inferred to be electrogenic. Does not
CC       transport K(+), Ca(2+) or Mg(2+).
CC   -!- ACTIVITY REGULATION: Na(+) extrusion is completely inhibited by the
CC       H(+) conductor carbonyl cyanide m-chlorophenylhydrazone (CCCP).
CC   -!- SUBUNIT: May form a heterooligomeric complex that consists of seven
CC       subunits: mnhA1, mnhB1, mnhC1, mnhD1, mnhE1, mnhF1 and mnhG1.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000305}; Multi-pass membrane
CC       protein {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the CPA3 antiporters (TC 2.A.63) subunit C
CC       family. {ECO:0000305}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=ABG67112.1; Type=Erroneous initiation; Evidence={ECO:0000305};
