Answer: keratin

Keratin is a protein that belongs to the family of fibrous structure proteins. It is the key component of claws, horns, hooves, nails and skin cells in animals. It is the main protein which protects the epithelial cells from stress or damage.

Extremely fragile skin, it blisters and forms flakes is indicative of mutation of proteins.
