KRT9
Description
The KRT9 (keratin 9) is a protein-coding gene located on chromosome 17.
Keratin 9 is a protein produced by the KRT9 gene in humans. It belongs to the type I cytokeratin family and is found exclusively in the outermost layer of the palms and soles. Mutations in the KRT9 gene can cause a genetic skin condition called epidermolytic palmoplantar keratoderma.
Keratin 9 is believed to play a critical role in the development and maintenance of the thick, tough skin of the palms and soles. It may contribute to the unique structure and function of these areas, either by directly participating in the formation of the skin tissue or by influencing its overall organization.
KRT9 is also known as CK-9, EPPK, EPPK1, K9.
