FUNCTION	K(+)/H(+) antiporter that extrudes potassium in exchange for external protons and maintains the internal concentration of potassium under toxic levels.
CATALYTIC ACTIVITY	Reaction=H(+)(out) + K(+)(in) = H(+)(in) + K(+)(out); Xref=Rhea:RHEA:29467, ChEBI:CHEBI:15378, ChEBI:CHEBI:29103; PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:29468;
case not defined <Property:Membrane> or <Property:Membrane=1>
SUBCELLULAR LOCATION	Cell membrane; Multi-pass membrane protein.
else case <Property:Membrane=2>
SUBCELLULAR LOCATION	Cell inner membrane; Multi-pass membrane protein.
end case
SIMILARITY	Belongs to the monovalent cation:proton antiporter 1 (CPA1) transporter (TC 2.A.36) family. NhaP2 subfamily.
