WebTheir myosin light chains bind Ca2+ and provide the main on–off switch for contraction. When the Ca 2+ concentration is low in resting muscle, no Ca 2+ binds to light chains, and the actin–myosin ATPase is off. Ca2+ that is released during activation binds to the light chains, turning on the ATPase and contraction. WebJun 26, 2024 · Figure 1. Regulation of myosin light-chain phosphatase (MLCP) through regulation of myosin phosphatase target subunit 1 (MYPT1).
