Summary: Predicted to be a structural constituent of skin epidermis. Involved in epithelial cell differentiation and negative regulation of epithelial cell proliferation. Predicted to be located in cell surface and intermediate filament cytoskeleton. Predicted to be active in keratin filament. Is expressed in several structures, including alimentary system; lower urinary tract; respiratory system; sensory organ; and skin. Used to study white sponge nevus. Human ortholog(s) of this gene implicated in white sponge nevus 1. Orthologous to human KRT4 (keratin 4). [provided by Alliance of Genome Resources, Dec 2024]

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.
