Slc18a3 Gene Summary [Mouse]

Predicted to enable acetylcholine:proton antiporter activity and monoamine:proton antiporter activity. Involved in neurotransmitter loading into synaptic vesicle; positive regulation of neuromuscular junction development; and positive regulation of synaptic transmission. Located in cytoplasm and terminal bouton. Is active in cholinergic synapse. Is expressed in several structures, including esophagus; heart; nervous system; sensory organ; and urinary system. Human ortholog(s) of this gene implicated in congenital myasthenic syndrome 21. Orthologous to human SLC18A3 (solute carrier family 18 member A3).
