| Tissue Specificity | High expression in all major cholinergic cell groups, including peripheral postganglionic parasympathetic cells, preganglionic sympathetic and parasympathetic cells, ventral spinal cord and brainstem motoneurons, cell groups in the basal forebrain, the habenula and the corpus striatum. Weakly expressed in the cortex and hippocampus. |
| Function | Electrogenic antiporter that exchanges one cholinergic neurotransmitter, acetylcholine or choline, with two intravesicular protons across the membrane of synaptic vesicles. Uses the electrochemical proton gradient established by the V-type proton-pump ATPase to store neurotransmitters inside the vesicles prior to their release via exocytosis. Determines cholinergic vesicular quantal size at presynaptic nerve terminals in developing neuro-muscular junctions with an impact on motor neuron differentiation and innervation pattern. Part of forebrain cholinergic system, regulates hippocampal synapse transmissions that underlie spatial memory formation. Can transport serotonin. |
