Cytoskeleton made of proteins
WebMar 22, 2024 · The cytoskeleton is a dynamic network of protein filaments found in the cytoplasm of all cells, including those of bacteria and archaea. It stretches from the cell nucleus to the cell membrane in eukaryotes and is composed of the same proteins in all organisms. It consists of microfilaments, intermediate filaments, and microtubules, all of ... WebIntermediate filaments are made of several strands of fibrous proteins that are wound together . These elements of the cytoskeleton get their name from the fact that their diameter, 8 to 10 nm, is between those of microfilaments and microtubules. Intermediate filaments consist of several intertwined strands of fibrous proteins.
