Importance of myosin
Witryna2 mar 2024 · Some myosin molecules bind to cargo and use the cytoskeleton to transport materials within the cell. Myosin II specifically functions to drive contraction of a muscle cell and … Witryna15 maj 2024 · The discovery of actin in the Albert Szent-Györgyi laboratory in 1942 represents one of the most important findings in all of biomedical sciences. It coincides with the beginnings of serious studies in muscle biochemistry, most significantly because it showed that the interaction of actin with myosin was involved in contraction.
