In this early work, however, the activating effects of the natural ligand, acetylcholine, were not measured and, also, atropine apparently only partially inhibited the receptor. In the current paper, therefore, we recloned this receptor (named A-type mAChR) and found that the cDNA sequence published in Shapiro et al.
