The human erythrocyte membrane skeleton consists of a network of short actin filaments cross-linked into a hexagonal network by long, flexible spectrin molecules. The lengths of the short actin filaments (33 +/- 5 nm) at the central junctions are proposed to be stabilized and limited by association with tropomyosin and the tropomyosin-binding protein, tropomodulin. Here, we use immunogold labelling followed by negative staining to specifically localize tropomodulin, tropomyosin and actin to the… CONTINUE READING
