Summary: Predicted to be a structural constituent of skin epidermis. Acts upstream of or within intermediate filament organization; keratinization; and morphogenesis of an epithelium. Predicted to be active in keratin filament. Is expressed in oral epithelium; skin; and tongue. Human ortholog(s) of this gene implicated in focal or diffuse nonepidermolytic palmoplantar keratoderma and pachyonychia congenita. Orthologous to human KRT6A (keratin 6A); KRT6B (keratin 6B); and KRT6C (keratin 6C). [provided by Alliance of Genome Resources, Dec 2024]

GeneRIFs: Gene References Into Functions

What's a GeneRIF?

These findings reveal that K6a/K6b modulate keratinocyte migration by regulating cell-matrix and cell-cell adhesion and highlight a role for keratins in collective cell migration.
Title: Keratin 6 regulates collective keratinocyte migration by altering cell-cell and cell-matrix adhesion.
Although K6a was not essential for mammary gland development, loss of both K6a and K6b resulted in an increase in PR-positive mammary epithelial cells and decreased proliferation after exposure to steroid hormones
Title: Keratin 6 is not essential for mammary gland development.

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.
