We investigated whether a human neurotransmitter receptor for acetylcholine (Ach) could couple Ach to light-sensitive pathways in Limulus photoreceptors. Two to three days after injection of human ml muscarinic mRNA into Limulus ventral photoreceptors the cells depolarized in response to Ach. © 1993.
