Fibrous proteins, also called scleroproteins, are long filamentous protein molecules.[1]

Fibrous proteins are only found in animals.

Fibrous proteins form 'rod' or 'wire' -like shapes and are usually inert structural or storage proteins. They are generally water-insoluble. Fibrous proteins are usually used to construct connective tissues, tendons, bone and muscle fiber.

Examples of fibrous proteins include keratins, collagens and elastins.

Fingernails and claws are made up of the common fibrous proteins, Keratin.
