Keratin, type I cytoskeletal 17 is a protein that in humans is encoded by the KRT17 gene.^[3][4][5][6]

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 Jackson-Lawler type pachyonychia congenita and steatocystoma multiplex.^[6]

Interactions

Keratin 17 has been shown to interact with CCDC85B.^[7]
