Keratin 16 is a protein that in humans is encoded by the KRT16 gene.[1][2][3]

Keratin 16 is a type I cytokeratin. It is paired with keratin 6 in a number of epithelial tissues, including nail bed, esophagus, tongue, and hair follicles. Mutations in the gene encoding this protein are associated with the genetic skin disorders pachyonychia congenita, non-epidermolytic palmoplantar keratoderma and unilateral palmoplantar verrucous nevus.[4]
