these data argue that anp uncouples the initial agonist-induced ca2+ transient from the increase in extent of myosin light chain phosphorylation either by inhibiting the ca2+-dependent activation of myosin light chain kinase or stimulating the activity of a phosphoprotein phosphatase capable of bringing about the rapid dephosphorylation of phosphorylated myosin light chains .
