The gene KRT15 (keratin 15) is mapped to human chromosome 17q21. It is an acidic intermediate filament protein. KRT15 protein is mainly present in epidermal, esophageal and uterine cervical epithelia and in corneal limbal cells. Keratin filaments are commonly arranged as heterotypic pairs and result in formation of multimeric filaments.

Application: All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org)and as a result, are supported by the most extensive characterization in the industry. The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link.

Biochem Physiol Actions: KRT15 (keratin 15) is a type I subtype of cytokeratin. Cytokeratins are essential for cell shape, motility and the integrity of the structure. During embryonic development, KRT15 is required for the formation of stratified epithelium tissue. It can serve as a marker for less differentiated basal epithelia and for small number of cells present around the hair follicle. Presence of high level of KRT15 protein (postnatally) is associated with malignant urothelial overgrowth. It is also variably expressed in oral squamous cell carcinoma and squamous intraepithelial neoplasm.
