Shedding in snakes is cyclical and derives from the differentiation of an intraepidermal shedding complex made of two different layers, termed clear and Oberhäutchen that determine the separation between the outer from the inner epidermal generation that produces a molt. The present comparative immunocytochemical study on the epidermis and molts of different species of snakes shows that a glycine‐cysteine‐rich...
The complex differentiation of snake epidermis largely depends on the variation in the production of glycine-cysteine-rich versus glycine-rich beta-proteins (beta-keratins) that are deposited on a framework of alpha-keratins. The knowledge of the amino acid sequences of beta-proteins in the snake Pantherophis guttatus has allowed the localization of a glycine-cysteine-rich beta-protein in the spinulated...
