Cytoskeleton intermediate filaments

WebThere are three types of fibers within the cytoskeleton: microfilaments, intermediate filaments, and microtubules ( see image below ). Here, we will examine each. Microfilaments thicken the cortex around the inner edge of a cell; like rubber bands, they resist tension. Microtubules are found in the interior of the cell where they maintain cell ...

Vimentin Intermediate Filaments: Regulation by Phosphorylation

WebThese varied functions are dependent upon cytoplasmic networks of actin microfilaments (6 nm), intermediate filaments (10 nm) and microtubules (23 nm), and their many associated proteins. In this chapter, I review what is known about the cytoskeletons of intermediate filaments and their associated proteins. WebThe cytoskeleton functions in maintaining the cell shape, resisting deformation, movement both inside (transport of vesicles within) and migratory movement, cell signaling, endocytosis and exocytosis, and cell division.

WebIntermediate Filaments [edit edit source] Intermediate Filaments are the thickest in cytoskeleton family. Unlike microfilaments, they don't anchor to the plasma membrane. They move in the cytoplasm around the nucleus. Because they are the thickest, they serve an important role in the stability of the cell's shape, forming hair, skin, etc. WebThe cytoskeleton is a complex, dynamic network of interlinking protein filaments present in the cytoplasm of all cells, including those of bacteria and archaea.
