Keratin (/ ˈ k ɛr ə t ɪ n / [1] [2]) is one of a family of structural fibrous proteins also known as scleroproteins. It is the key structural material making up scales, hair, nails, feathers, horns, claws, hooves, and the outer layer of skin in vertebrates. Keratin also protects epithelial cells from damage or stress. Keratin is extremely ...
The initial step in forming keratin is the alignment of type I and type II keratin polypeptides to ... reaction confirmed the expression of the full-length KRT81 ...
This central domain of the chain provides the molecular alignment in the keratin structure and makes the chains form coiled dimers in solution. The end-domain sequences of type I and II cytokeratin chains contain in both sides of the rod domain the subdomains V1 and V2, which have variable size and sequence.
The first sequences of keratins revealed that keratins could be grouped into two categories based on their sequence homologies. [1] [2] These two groups of keratins were named as type I and type II keratins. [2]

Alpha-keratin, or α-keratin, is a type of keratin found in mammalian vertebrates. This protein is the primary component in hairs , horns , claws , nails and the epidermis layer of the skin . α-keratin is a fibrous structural protein , meaning it is made up of amino acids that form a repeating secondary structure.
