Myosin activator
WebSep 7, 2024 · MYH7 (myosin) is the molecular engine of the heart, converting the chemical energy of adenosine triphosphate (ATP) into movement. Force production at the level of the cardiomyocyte occurs when millions of myosin engines combine, pulling each of ≈50 sarcomeres per heart cell ≈10% of their resting length closer ( Figure [A ]).
