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. The tail of spectrin tetramers binds with a protein cluster of short ...
