Smallest protein elements of the cytoskeleton
WebbCollectively, this network of protein fibers is known as the cytoskeleton. There are three types of fibers within the cytoskeleton: microfilaments, intermediate filaments, and microtubules ( Figure ). Here, we will examine each. Microfilaments thicken the cortex around the inner edge of a cell; like rubber bands, they resist tension. Webb23 jan. 1998 · The cytoskeleton is responsible for cell shape, motility, migration, and polarity, and for establishing intercellular contacts to produce tissue architecture. In addition, the cytoskeleton plays many roles inside the cell. For example, in cell division it forms the scaffold on which chromosomes are segregated to daughter cells and …

WebbAlso known as microfilaments, these are the smallest filaments (in diameter) in the cell, at about 7nm in diameter. They are made up of actin monomers which polymerise into filaments, that have two strands which wrap around each other. Actin filaments are important in cell shape and cell motility. About half the actin in a cell is unpolymerised.
