Isolation of a cholinergic proteolipid receptor from electric tissue

A proteolipid protein having a high affinity for methyl (14)C-hexamethonium, (3)H-p-(trimethylammonium)-benzene diazonium fluoroborate, and (acetyl-1-(14)C)choline chloride was isolated and purified from the electric tissue of Torpedo marmorata and Electrophorus electricus. At variance with the "receptor proteolipid" from the brain the one from electric tissue apparently does not bind atropine sulfate.
