Summary: Predicted to enable carbohydrate binding activity and protein heterodimerization activity. Predicted to be a structural constituent of skin epidermis. Acts upstream of or within establishment of skin barrier and negative regulation of inflammatory response. Located in keratin filament. Is active in cornified envelope. Is expressed in autopod; nose; skin; and tongue. Used to study epidermolytic hyperkeratosis. Human ortholog(s) of this gene implicated in KRT1-related nonepidermolytic palmoplantar keratoderma; epidermolytic hyperkeratosis; epidermolytic hyperkeratosis 1; epidermolytic palmoplantar keratoderma 2; and keratosis palmoplantaris striata 3. Orthologous to human KRT1 (keratin 1). [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.
