Isolation and functional characterization of the chick M5 muscarinic acetylcholine receptor gene.
The chick is a widely used system for study of the actions of muscarinic acetylcholine receptors in the cardiovascular, visual, and nervous systems. We report the isolation and functional analysis of the gene encoding the chick M5 muscarinic receptor. RT-PCR analysis indicates that the M5 receptor is expressed at low levels in embryonic chick brain and heart. When expressed in stably transfected Chinese hamster ovary cells, the M5 receptor exhibits high-affinity binding to muscarinic antagonists and mediates robust activation of phospholipase C activity.
