miozyna
Miozyna is a protein essential for muscle contraction and movement in living organisms. It belongs to the class of motor proteins known as myosin superfamily, which play a critical role in cellular processes involving force generation and movement. Myosin molecules are composed of heavy chains and light chains, with the heavy chains forming a long tail and a globular head region responsible for binding to actin filaments and hydrolyzing adenosine triphosphate (ATP).
In skeletal and cardiac muscle, myosin interacts with actin filaments in a process known as the sliding
Myosin is not limited to muscle tissue; it is also found in non-muscle cells, where it contributes
Deficiencies or mutations in myosin genes can lead to various myopathies, muscular dystrophies, and other disorders
