Protein-coding gene in the species Homo sapiens
Keratin 9 is a protein that in humans is encoded by the KRT9 gene .[ 5] [ 6]
Keratin 9 is a type I cytokeratin . It is found only in the terminally differentiated epidermis of palms and soles . Mutations in the gene encoding this protein cause epidermolytic palmoplantar keratoderma .[ 7]
