WebSep 8, 2009 · Red blood cells are amazingly deformable structures able to recover their initial shape even after large deformations as when passing through tight blood capillaries. The reason for this exceptional property is found in the composition of the membrane and the membrane-cytoskeleton interaction. WebSpectrin is a major component of the normal red blood cell (RBC) cytoskeleton and consists of two intercoiled non-identical filamentous subunits that form heterodimers. The chain heads of each dimer pair bind with opposite subunit heads of another dimer pair to form tetramers.
