Keratin 14 is a member of the type I keratin family of intermediate filament proteins. Keratin 14 was the first type I keratin sequence determined.⁵ Keratin 14 is also known as cytokeratin-14 (CK-14) or keratin-14 (KRT14). In humans it is encoded by the KRT14 gene.⁶⁷⁸

Keratin 14 is usually found as a heterodimer with type II keratin 5 and form the cytoskeleton of epithelial cells.

Pathology

Mutations in the genes for these keratins are associated with epidermolysis bullosa simplex⁹ and dermatopathia pigmentosa reticularis, both of which are autosomal dominant mutations.¹⁰
