Function

function

Mnh complex is a Na+Li+/H+ antiporter involved in Na+ and/or Li+ excretion. Na+/H+ antiport consumes a transmembrane electrical potential, and is thus inferred to be electrogenic. Does not transport K+, Ca2+ or Mg2+.

Activity regulation

Na+ extrusion is completely inhibited by the H+ conductor carbonyl cyanide m-chlorophenylhydrazone (CCCP).
