title: The fibrous protein of fish epidermis.
abstract: Fibrous proteins have been isolated from fish epidermis and shown to have physical and chemical properties similar to those of mammalian epidermal keratins. These results are most consistent with our hypothesis that hard keratins evolved late in evolution and there was not a common precursor of mammalian epidermal and hard keratin in primitive vertebrates.
