these observations demonstrate that inositol trisphosphate formation and activation of cyclic nucleotide phosphodiesterase ( and hence most likely myosin light chain kinase ) by calmodulin precede myosin light chain phosphorylation and that these events are sufficiently rapid to mediate the contractile response of neurally stimulated tracheal smooth muscle .
