Summary
Predicted to be a structural constituent of skin epidermis. Predicted to be involved in intermediate filament organization and keratinization. Is active in cornified envelope. Is expressed in epidermis; palmar pad; and skin. Orthologous to human KRT77 (keratin 77). [provided by Alliance of Genome Resources, Nov 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.
