KRT14 (keratin 14) is a protein-coding gene located on chromosome 17q21.2.This gene encodes a member of the keratin family, the most diverse group of intermediate filaments. The encoded protein, a type I keratin, normally exists as a heterotetramer with two keratin 5 molecules and one type II keratin. Together, they form the cytoskeleton of epithelial cells. At least one pseudogene has been identified at 17p12-p11. Mutations in the genes for these keratins have been associated with the following diseases.

In bronchial carcinoma, high expression of keratin 14 may be associated with nodal metastasis and poor survival.
