Part of the book: The Biochemical Guide to Proteins


Myosin is a protein widespread in living organisms it occurs in lower organisms: amoebas, nematodes, fungi, but also in plants and animals. So far, over a dozen classes of myosin have been discovered that are involved in processes such as: the conversion of electrical signals into a nerve impulse, exocytic and endocytic transport, cell division, transport of cytoplasm between cells, contraction of muscle cells. Type II myosin is the one that is responsible for the possibility of muscle cell contraction, thanks to the ability to hydrolyze ATP and bind to actin.

Keywords: myosins, phototransduction, endocytic transport, cell division, muscle cell, amoebas, nematodes, fungi
