A second pathway of activation of the Torpedo acetylcholine receptor channel

~ C05a894946fc7d7d8be6e488531a45b8.200x200

We have studied the interaction of the reversible acetylcholine esterase inhibitor (-)physostigmine (D-eserine) with the nicotinic acetylcholine receptor (nAChR) from Torpedo marmorata electric tissue by means of ligandinduced ion flux into nAChR-rich membrane vesicles and of equilibrium binding. We find that (—)physostigmine induces cation flux (and also binds to the receptor) even in the...
