protein in skin, hair, and nails providing structural support
Keratin 6 (K6) is a type of protein found in the epithelial cells of the skin, hair, and nails. It plays a crucial role in the structural integrity and resilience of these tissues. Mutations in the KRT6 gene, which encodes Keratin 6, can lead to disorders such as pachyonychia congenita, characterized by thickened nails and other skin abnormalities.
