MGI Phenotype FUNCTION: 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. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2015]
PHENOTYPE: Homozygotes for targeted null mutations develop extensive skin blistering after birth and die by 2 days of age. If keratin 16 is also expressed in skin, development is normal but later alopecia, chronic skin ulcers and stratified epithelial defects occur. [provided by MGI curators]
