monoatomic ion antiporter activity involved in regulation of postsynaptic membrane potential
monoatomic ion antiporter activity involved in regulation of presynaptic membrane potential
monocarboxylate:sodium symporter activity +
NADH dehydrogenase (ubiquinone) activity
orotate:monoatomic anion antiporter activity
Enables the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: orotate(out) + anion (in) = orotate (in) + anion (out).
