•structural proteins-maintaining the cell shape, (for example, proteins are structural elements in connective tissues like cartilage and bone in vertebrates),  

•Enzymes - catalyze the biochemical reactions in cells-.

•  Monitors- changing their activity in response to metabolic signals

•Part of the extracellular matrix or involved in intercellular communication…
