GlossaryKeratin 2 (K2)

protein providing structural strength to skin, hair, and nails

Keratin 2 (KRT2) is a type of protein found in the outer layer of the skin, hair, and nails. It plays a crucial role in providing structural strength and resilience to these tissues, helping to protect them from damage and wear. Mutations in the KRT2 gene can lead to skin disorders such as ichthyosis bullosa of Siemens, which is characterized by blistering and scaling of the skin.
