WebMyosin light chain phosphatase (MLCP) is responsible for the dephosphorylation of the regulatory light chain (RLC) of the motor protein myosin-II, and so negatively regulates actomyosin-based contractility. Agonist-induced contraction of smooth muscle is often associated with a sensitization of the contractile apparatus to intracellular Ca ++.
