WebSmooth muscle contraction, induced by acetylcholine through the muscarinic M3 receptor, starts with the release of Ca2+ from intracellular stores. Ca 2+ binds calmodulin that is complexed with myosin light chain kinase. This leads to activation of the kinase and subsequent phosphorylation of regulatory myosin light-chain at serine-19.
