Abstract
Clone PC12 of a rat sympathetic neuron cell line binds alpha-bungarotoxin and exhibits carbamoylcholine-stimulated uptake of sodium ions. Concentrations of alpha-bungarotoxin that saturate the alpha-bungarotoxin-binding site have no effect on agonist-stimulated sodium uptake. Conversely, antibodies against eel acetylcholine receptor block the agonist-induced sodium flux but fail to recognize the alpha-bungarotoxin-binding component. Detergent extracts of the PC12 clone inhibit the ability of antibody to eel acetylcholine receptor to recognize 125I-alpha-bungarotoxin-acetylcholine receptor complexes derived from muscle. These results distinguish between a ganglionic nicotinic acetylcholine receptor and an alpha-bungarotoxin-binding component on these cells, and provide evidence for antigenic similarities between muscle acetylcholine receptor and ganglionic acetylcholine receptor.Entities:
