K10 is a type of protein that plays a crucial role in the structure and function of cells. It is part of the keratin family, which is known for providing strength and resilience to various tissues, including skin, hair, and nails. K10 is particularly important in the epidermis, the outer layer of skin, where it helps maintain its integrity and protects against environmental damage. K10 is encoded by the KRT10 gene, which is located on chromosome 17 in humans. Mutations in this gene can lead to skin disorders, such as ichthyosis, characterized by dry, scaly skin. Understanding K10 and its functions can help researchers develop treatments for these conditions and improve skin health.
