WebDec 28, 2024 · Mavacamten is a specific inhibitor of cardiac myosin ATPase that lengthens the total cycle time (tc) of the ATPase cycle and also reduces the rate of phosphate release from myosin heads without slowing ADP release [ 22, 31] ( Figure 3 ). This leads to a reduction in duty ratio and ensemble force. WebActin has binding sites for myosin attachment. Strands of tropomyosin block the binding sites and prevent actin–myosin interactions when the muscles are at rest. Troponin consists of three globular subunits.
