Summary: Predicted to be a structural constituent of skin epidermis. Involved in defense response to other organism; morphogenesis of an epithelium; and wound healing. Acts upstream of or within Wnt signaling pathway; intermediate filament organization; and keratinization. Predicted to be active in keratin filament. Is expressed in alimentary system; genitourinary system; sensory organ; and skin. 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]

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.
mK6a and mK75 thus exhibit temporally distinct, and spatially opposed, expression patterns in the companion layer (Cl) during postnatal anagen.
Title: Keratin expression provides novel insight into the morphogenesis and function of the companion layer in hair follicles.
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.
