Enables acetylcholine transmembrane transporter activity. Involved in several processes, including cholinergic synaptic transmission; nematode larval development; and regulation of nematode pharyngeal pumping. Located in neuron projection; organelle membrane; and synapse. Expressed in neurons;
pm2; somatic nervous system; and in male. Human ortholog(s) of this gene implicated in Alzheimer's disease; Huntington's disease; and congenital myasthenic syndrome 21. Is an ortholog of human SLC18A3 (solute carrier family 18 member A3).
