Acetylcholine translocating protein: mediatophore at rat neuromuscular synapses

The neuromuscular synapses of the rat sternomastoid muscles contain a membrane protein, mediatophore, that endows artificial membranes with a calcium-dependent acetylcholine release mechanism. Mediatophore and choline acetylase had similar distributions along the muscle. Sciatic nerve membranes contain mediatophore, and a purified preparation was obtained from the nerve.
