Cytoskeleton of rbc
WebThe human red blood cell membrane is packed with a regular array of proteins and protein complexes attached at intervals to the underlying cytoskeleton. The … WebIn red blood cells (RBCs), the cytoskeleton consists of a two-dimensional network of spectrin proteins. Our analysis of the wave vector and frequency dependence of the fluctuation spectrum of RBCs indicates that the spectrin network acts as a confining potential that reduces the fluctuations of the lipid bilayer membrane.
