Cytoskeleton of red blood cells

WebSpecialized cells are usually characterized by a very specific cortical actin cytoskeleton. For example, in red blood cells, the cell cortex consists of a two-dimensional cross-linked elastic network with pentagonal or hexagonal symmetry, tethered to the plasma membrane and formed primarily by spectrin, actin and ankyrin. WebThat said, the prokaryotic cytoskeleton is not made of tubulin or actin, but of proteins that resembles these eukaryotic proteins. I refer you to the primary review article: "The evolution of the cytoskeleton" in the Journal of Cell Biology (Published August 22, 2011 // JCB vol. 194 no. 4 513-525) by Bill Wickstead and Keith Gull.
