The cloned cDNAs encoding the four subunits of the Torpedo californica acetylcholine
receptor, each carried by a simian virus 40 vector, direct the synthesis of the functional
receptor in a combined expression system consisting of COS monkey cells and Xenopus
oocytes. Our results suggest that all four subunits are required to elicit a normal nicotinic
response to acetylcholine, whereas only the α-subunit is indispensable for α-bungarotoxin
binding activity.
