They contain repetitive amino acid sequences in their structure that provides strength to the structure.
They are very less sensitive to any change in pH, temperature, as well as enzymatic digestion.
They are usually involved in the formation of connective tissue.
Example of fibrous protein- Actin, myosin, elastin, keratin.
Mutation I believe is the answer
