Keratin 17 is a type I cytokeratin. It is found in nail beds, hair follicles, sebaceous glands, and other epidermal appendages. Mutations in the gene encoding this protein lead to PC-K17 (previously known as Jackson-Lawler) type pachyonychia congenita and steatocystoma multiplex.^[8]

Interactions

Keratin 17 has been shown to interact with CCDC85B.^[9]
