Keratin 13

Keratin 13 (or cytokeratin 13) is a is_associated_with::protein that in humans is encoded by the KRT13 is_associated_with::gene.

Keratin 13 is a is_associated_with::type I cytokeratin, it is paired with is_associated_with::keratin 4 and found in the suprabasal layers of non-cornified stratified epithelia. Mutations in the gene encoding this protein and keratin 4 have been associated with the autosomal dominant disorder is_associated_with::White Sponge Nevus.

K13 is negative in buccal epithelium.
