Keratineintermediaire

Keratineintermediaire refers to intermediate filament proteins that are part of the keratin family. These proteins are structural components found in epithelial cells of vertebrates. They form a complex network within the cytoplasm, contributing to the mechanical strength and resilience of cells and tissues. Keratins are a diverse group of proteins, and intermediate filament keratins are distinguished by their specific molecular structure and assembly into stable filaments. These filaments play a crucial role in maintaining cell shape, protecting cells from physical stress, and organizing intracellular components.

The assembly of keratin intermediate filaments is a complex process involving the formation of coiled-coil dimers, which then associate into protofilaments and subsequently into mature filaments. This intricate structure allows them to withstand significant mechanical forces. Different types of keratin intermediate filaments are expressed in various epithelial tissues, with specific combinations contributing to the unique properties of tissues like skin, hair, nails, and the lining of internal organs. Mutations in keratin genes can lead to a range of genetic disorders affecting these tissues, highlighting the critical role of these proteins in cellular and organismal health. The study of keratin intermediates is vital for understanding cellular mechanics and developing treatments for keratin-related diseases.
