Webb23 jan. 1998 · The basic building blocks of the cytoskeleton include actin microfilaments (about 7 nm in diameter), tubulin microtubules (about 24 nm in diameter), and a variety of intermediate filaments (about 10 nm in diameter). Actin cytoskeleton of mouse embryo fibroblasts, stained with phalloidin Microfilaments, also known as actin filaments, are composed of linear polymers of G-actin proteins, and generate force when the growing (plus) end of the filament pushes against a barrier, such as the cell membrane. Visa mer The cytoskeleton is a complex, dynamic network of interlinking protein filaments present in the cytoplasm of all cells, including those of bacteria and archaea. In eukaryotes, it extends from the cell nucleus to the Visa mer Eukaryotic cells contain three main kinds of cytoskeletal filaments: microfilaments, microtubules, and intermediate filaments.
