MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene is a member of the type II keratin family clustered on the long arm of chromosome 12. Type I and type II keratins heteropolymerize to form intermediate-sized filaments in the cytoplasm of epithelial cells. The product of this gene typically dimerizes with keratin 18 to form an intermediate filament in simple single-layered epithelial cells. This protein plays a role in maintaining cellular structural integrity and also functions in signal transduction and cellular differentiation. Mutations in this gene cause cryptogenic cirrhosis. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Jan 2012]
PHENOTYPE: Mice homozygous for a null allele show partial background-sensitive embryonic lethality, placental defects, impaired female fertility, abnormal hematopoiesis, diarrhea, colorectal hyperplasia, anorectal prolapse, and high liver sensitivity to toxins, apoptotic stimuli and diet-induced steatosis.
