No. Only living things are made of cells. Proteins are not living.
There are 20 amino acids used to make proteins by all living things. There are a few additional amino acids that some archaebacteria use to make proteins that are not used by other living things. There are many more synthetic amino acids that can be made, but while synthetic proteins can be made with them no living thing uses these additional amino acids.
Proteins are found in all living things as well as needed by living things. Animals and vegetables are good sources of protein.
Biology is the study of living things not proteins
Collagen and Keratin, both fibrous proteins.
To make proteins.

These special proteins are called enzymes.
Proteins are not of themselves alive. However, proteins are the building blocks of all living things.
