01

Overview

Keratin, type I cytoskeletal 40 (KRT40) is a member of the acidic type I keratin family and forms part of the intermediate filament network in epithelial cells, contributing to the cytoskeletal structure alongside actin and microtubules. It is encoded on chromosome 17q12-q21 and is mainly involved in structural support, cellular integrity, and epithelial cell differentiation. KRT40 may play a specific role in late hair differentiation. Mutations or dysfunction have been associated with certain skin disorders such as steatocystoma multiplex and with heart fibrosarcoma, but it is not a classical drug target such as a receptor, enzyme, or transporter.
