Keratin, high-sulphur matrix protein
Family of Keratin, high-sulfur matrix proteins. The keratin products of mammalian epidermal derivatives such as wool and hair consist of microfibrils embedded in a rigid matrix of other proteins. The matrix proteins include the high-sulphur and high-tyrosine keratins, having molecular weights of 6-20 kDa, whereas microfibrils contain the larger, low-sulphur keratins (40-56 kDa).
