Biological function summary

Alpha cardiac myosin heavy chain contributes to the cyclical interaction with actin filaments which results in muscle contraction. It forms part of the myosin molecule complex together with its two light chains. The ATPase activity of alpha MHC enables it to convert chemical energy from ATP hydrolysis into mechanical work driving the sliding of actin filaments. This process is important for the maintenance of cardiac muscle contractility and heart function.

Pathways

Alpha cardiac myosin heavy chain functions as a central element in the cardiac muscle contraction pathway. This pathway is essential for the effective pumping of blood by the heart. In this pathway alpha MHC interacts with actin to facilitate cross-bridge cycling which drives muscle contraction. Additionally it relates closely to other myosin heavy chains such as beta-myosin heavy chain which expresses depending on developmental stage or physiological condition ensuring adaptability of cardiac muscle performance.
