The New Keratin Nomenclature

The document outlined a revision of the keratin nomenclature due to the identification of 54 keratin genes, up from the original 19. This revision aimed to establish a logical numbering system, particularly for keratins in the hair follicle, while retaining the original names for keratins K1–K19. Changes mainly affected hair shaft and inner root sheath keratins. The revised system was intended for future publications to reflect the diversity of keratins, which vary by cell type and differentiation state, emphasizing their significance in dermatology research and the potential for discovering new keratins in other mammals.
