Myosins (/ ˈmaɪəsɪn, - oʊ -/ [1][2]) are a family of motor proteins (though most often protein complexes) best known for their roles in muscle contraction and in a wide range of other motility processes in eukaryotes. They are ATP -dependent and responsible for actin -based motility.

Feb 7, 2021 · Actin and myosin are both proteins that are found in every type of muscle tissue. Thick myosin filaments and thin actin filaments work together to generate muscle contractions and movement. Myosin is a type of molecular motor and converts chemical energy released from ATP into mechanical energy.

Aug 27, 2024 · Myosin is a filamentous protein classified as a motor protein due to its ability to convert chemical energy from ATP hydrolysis into mechanical work. A single myosin molecule comprises six subunits: two heavy chains and four light chains. The structural organization of these chains is essential for its function.

In this review, to better understand these fundamental issues regarding hypertrophy and atrophy in skeletal muscle, we focus on the thick filament and its main component, myosin.

Myosin is the predominantly expressed protein in muscle and serves as the molecular motor responsible for muscle contraction. It is also involved in actin-based cellular motility. Myosin has been extensively studied in biochemistry, and its enzymatic pathway and mechanism have been determined through rapid reaction studies.

Myosins are among the most fascinating enzymes in biology. As extremely allosteric chemomechanical molecular machines, myosins are involved in myriad pivotal cellular functions and are frequently sites of mutations leading to disease phenotypes.

Jul 21, 2024 · Myosin is a motor protein that plays a significant role in cellular movement and structure. Its complex architecture is tailored to its function, featuring a head, neck, and tail region. The head domain is particularly noteworthy, as it binds …

Myosins are cytoskeletal motor proteins that use energy derived from ATP hydrolysis to generate force and movement along actin filaments.

Myosins are key components of the eukaryotic cytoskeleton, providing motility for a broad diversity of cargoes. Therefore, understanding the origin and evolutionary history of myosin classes is crucial to address the evolution of eukaryote cell biology.

Myosins are a superfamily of molecular motors that convert the chemical energy of ATP hydrolysis into directed motion along the filamentous protein actin.
