Supplementary information

Myosin is a molecular motor protein responsible for converting chemical energy into mechanical force facilitating muscle contraction and cellular movement. Also known as the myosin heavy chain (MHC) or MYH myosin has a commonly referenced heavy chain Myosin heavy chain 1 (MYH1) with a molecular mass of roughly 200 kDa. Myosin is broadly expressed in muscle tissues including skeletal cardiac and smooth muscles and appears in various isoforms depending on the specific type of muscle tissue.
Biological function summary

Myosin interacts intricately with actin filaments to form a complex that executes muscle contraction and cell motility. Myosin heads bind to actin filaments employing ATP hydrolysis to generate motion. This protein is a fundamental component of the sarcomere the structural unit of muscle fibers and works in concert with other proteins like tropomyosin and troponin to regulate muscle contraction.

Pathways

Myosin has a significant role in the muscle contraction and cell motility pathways. Myosin and actin interaction is central to the sliding filament theory which is an essential part of the muscle contraction pathway. Myosin is also involved in non-muscle cell movement through the actin-myosin contractile ring in the process of cytokinesis. Myosin interacts with proteins such as actin and ATP in these pathways to facilitate cellular processes.

Myosin has connections to conditions like hypertrophic cardiomyopathy and various myopathies. Mutations in the myosin heavy chain can lead to hypertrophic cardiomyopathy affecting the heart's ability to pump blood effectively. Additionally disruptions in myosin function can contribute to muscular diseases impairing muscle strength and function. Myosin's interaction with actin and related sarcomeric proteins is pivotal in these pathological scenarios often resulting in altered muscle dynamics and associated clinical manifestations.
