The 23rd variety of them discovered has only been found in pancreatic carcinoma cells treated with sodium butyrate.

The hereditary disease white sponge nevus is caused by mutations in the mucosal variety of them, while mutations in those specific to the epidermis cause Weber-Cockayne and Dowling- Meara blistering. William Astbury's X-ray diffraction photos of these molecules led to the postulation of alpha helices, and it was later discovered that isopeptide bonds between a carboxyl group of glutamic acid and the amino group of lysine residue help form their cross-linked design. Like collagens, their high proportion of glycine allows for a closely-packed structure, and the relative abundance of cysteine allows for many disulfide bridges to be formed, which causes them to be rigid and waterproof. FTP, name this family of structural proteins, which compose hard surfaces like calluses, claws, hooves, and hair.
