a host of cellular enzymes, cellular structural components (microtubules, microfilaments, and so on), cell membrane proteins that function as carriers, pumps and signal transducers, extracellular matrix components including collagen and elastin and biomolecules which incorporate protein such as proteoglycans and glycoproteins, and others. There are too many examples of proteins present to be listed here, but they generally fall into two categories: structural proteins which form parts of cells and/or the extracellular matrix, and enzymes which function as catalysts to speed up biochemical reactions. Good question!

Enzymes are proteins. A certain percentage of every cell in the body is made of proteins.
