Description | Protein which is a component or which is associated with the cytoskeleton, a dynamic three-dimensional filamentous structure in the cytoplasm. The cytoskeleton is both a muscle and a skeleton, and its roles include maintenance of cell shape, cell movement (in eukaryotes), cytokinesis, and the organization of the organelles within the cell. This includes the major components of cytoskeleton; microfilaments (actin-like proteins), microtubules (tubulin-like proteins) and intermediate filaments (mostly in eukaryotes) and prokaryotic MinD-ParA proteins. Originally not thought to exist in prokaryotes, but now known to have the same functions as in eukyaryotes |
