Summary: Predicted to enable scaffold protein binding activity. Predicted to be a structural constituent of skin epidermis. Involved in several processes, including intermediate filament polymerization; regulation of cell migration; and response to mechanical stimulus. Located in cytoplasm; keratin filament; and plasma membrane. Is active in cornified envelope. Is expressed in several structures, including alimentary system; epithelium; genitourinary system; integumental system; and sensory organ. Used to study epidermolysis bullosa simplex Dowling-Meara type. Human ortholog(s) of this gene implicated in Dowling-Degos disease; epidermolysis bullosa simplex; and epidermolysis bullosa simplex with mottled pigmentation. Orthologous to human KRT5 (keratin 5).

Taken together, our data demonstrated that Krt5-expressing cells could be involved in the natural pancreas self-healing process and the renewal of beta cells after AP in adult mice. It is promising that promoting conversion of Krt5-expressing cells into functional beta cells may be a novel method to mitigate the development of diabetes mellitus after AP in vivo.

widespread destruction of airway and alveolar epithelial cells following severe influenza infection triggers a wound-healing response that initiates in the airways with the proliferation of rare airway-resident SOX2+ Lin- progenitor cells. These cells then give rise to nascent KRT5+ cells in remodeled airways and populate the damaged alveolar parenchyma.

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.
