Intermediate filament proteins are a type of cytoskeletal component found in the cells of many organisms. They provide structural support and help maintain the shape of cells. Unlike other cytoskeletal elements, such as microtubules and actin filaments, intermediate filaments are more stable and resistant to mechanical stress. These proteins are composed of various subunits, including keratins, vimentin, and neurofilaments, which vary depending on the cell type. They play crucial roles in cellular functions, such as anchoring organelles and facilitating cell-cell connections, contributing to the overall integrity of tissues.
