WebThe cytoskeleton is unique to eukaryotic cells. It is a dynamic three-dimensional structure that fills the cytoplasm. This structure acts as both muscle and skeleton, for movement and stability. The long fibers of the cytoskeleton are polymers of subunits. WebFeb 22, 2024 · 1. The Role of Ezrin as the Cross-Linker between Membrane Proteins and the Actin Cytoskeleton. Ezrin is a protein which links membrane proteins such as receptors, ion channels, and transporters to the actin cytoskeleton directly or indirectly through scaffold proteins, as shown in Figure 3. Figure 3.
