Cytokeratins, a group of at least 29 different proteins, are characteristic of epithelial and trichocytic cells. Cytokeratins 4, 5, 6 and 8 are members of the type II neutral-to-basic subfamily. Cytokeratin peptide 4 (59 kDa) is the secondary type II keratin expressed in non cornified stratified squamous epithelia. Cytokeratin peptide 5 (58 kDa) is the primary type II keratin in stratified epithelia, while cytokeratin type 8 (52 kDa) is a major type II keratin in simple epithelia. Cytokeratin 6 (56 kDa) is a "hyperproliferation" cytokeratin expressed in tissues with natural or pathological high turnover. Cytokeratins 10, 13 and 18 are members of the type I acidic subfamily. Cytokeratin peptide 10 (56 kDa) is the secondary type I keratin expressed in cornified epithelia. Cytokeratin 13 (54 kDa) is the secondary type I keratin expressed in non-cornified stratified squamous epithelia. Cytokeratin 18 (45 kDa) is the primary type I keratin expressed in simple epithelial cells. Cytokeratin is a heterotetramer of two type I and two type II keratins. Keratin 1 is generally associated with keratin 10. Defects in Cytokeratin are a cause of epidermolytic hyperkeratosis, also known as bullous congenital ichthyosiform erythroderma (BIE), which is a hereditary skin disorder characterized by blistering and a marked thickening of the stratum corneum. Defects in Cytokeratin are also the cause of Curth Macklin type ichthyosis hystrix, nonepidermolytic palmoplantar keratoderma, annular epidermolytic ichthyosis and keratosis palmoplantaris striata III (PPKS3). PPKS3 is an autosomal dominant disorder affecting palm and sole skin where stratum corneum and epidermal layers are thickened. There is no involvement of nonpalmoplantar skin, and both hair and nails are normal.
