Abstract excerpt
Verapamil, a Ca(2+) channel blocker widely used in clinical practice, also affects the properties of frog and mouse muscle acetylcholine receptor (AChR). Here, we examine the mechanism of action of verapamil on human wild-type and slow-channel mutant muscle AChRs harboring in any subunit a valine-to-alanine mutation of 13' residue of the pore-lining M2 transmembrane segment. Verapamil, after a pre-treatment of...
