Summary: The protein encoded by this gene is a member of the keratin gene family. The keratins are intermediate filament proteins responsible for the structural integrity of epithelial cells and are subdivided into cytokeratins and hair keratins. The encoded protein is a cytokeratin and acts as an innate immune system effector, promoting the inflammatory response upon breach of the skin barrier. Defects in this gene are a cause of pachyonychia congenita. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2015]

What's a GeneRIF?

Study identified iRHOM2 as a novel regulator of K16 in humans and mice, with important implications for palmoplantar keratodermas, wound healing, inflammatory skin disease and cancers.
Title: Rhomboid family member 2 regulates cytoskeletal stress-associated Keratin 16.
we show that the loss of Krt16 function in mice causes the development of prominent calluses on the plantar side of front and hind paws, which significantly compromise mobility.
Title: Keratin 16-null mice develop palmoplantar keratoderma, a hallmark feature of pachyonychia congenita and related disorders.
Long-term alteration in the expression of keratins 6 and 16 is seen in the epidermis of mice after chronic UVB exposure.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
