KRT8 - keratin 8 Gene
Also Known as K8; KO; CK8; CK-8; CYK8; K2C8; CARD2
Species: Homo sapiens
About KRT8
This gene has 18 transcripts (splice variants), 116 orthologues, 68 paralogues and is associated with 1 phenotype. Biased expression in colon (RPKM 581.2), small intestine (RPKM 486.1) and 13 other tissues.
Summary
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]
