Formalin-fixed and paraffin-embedded human skin squamous cell carcinoma (A, 4 µm), prostate hyperplasia (B, 4 µm), and human tonsil tissue (C, 4 µm) stained with KRT14 monoclonal antibody, clone D19-N (Cat # MAB9766) shows strong positive cytoplasmic immunostaining of the neoplastic cells (A), strong positive cytoplasmic immunostaining in the basal cells of the normal and benign glands (B), and positive cytoplasmic immunostaining of the squamous epithelial cells (C).

This gene encodes a member of the keratin family, the most diverse group of intermediate filaments. This gene product, a type I keratin, is usually found as a heterotetramer with two keratin 5 molecules, a type II keratin. Together they form the cytoskeleton of epithelial cells. Mutations in the genes for these keratins are associated with epidermolysis bullosa simplex. At least one pseudogene has been identified at 17p12-p11. [provided by RefSeq
