Proteins in a cell
WebbProteins also have structural or mechanical functions, such as actin and myosin in muscle and the proteins in the cytoskeleton, which form a system of scaffolding that maintains cell shape. Other proteins are important in cell signaling, immune responses, cell adhesion, and the cell cycle. WebbProteins are among the most abundant organic molecules in living systems and are way more diverse in structure and function than other classes of macromolecules.
