CYTOSKELETON BY: JUNAIDIKRAM 2. 37-39, D-7400 Tübingen, FRG, It is reasonable to assume that in 1976 around 95% of experimental biologists were 100 issues of, To read this article in full you will need to make a payment. Note that the cytoskeleton is very extensive. Myosin is one superfamily of cytoskeletal motors, walking along the F-actin filaments. Microtubules, microfilaments (actin filaments), and intermediate filaments. The cytoskeleton is a network of different protein fibers that provides many functions: it maintains or changes the shape of the cell; it secures some organelles in specific positions; it enables movement of cytoplasm and vesicles within the cell; and it enables the cell to move in response to stimuli. Cytoskeleton • It is a network of protein filaments in the cytoplasm of a cell • It provides structural framework to the cell.it also helps in the cell movement and movement of cytoplasmic components during several processes such as phagocytosis,endocytosis and exocytosis.
