Structural comparison of several actin-binding macromolecules.
The cytoskeletal components, macrophage actin-binding protein and filamin, were dried from glycerol and examined by low-angle rotary shadowing electron microscopy. Both are elongate, flexible molecules whose general morphologi is similar to that of erythrocyte spectrin. Neither actin-binding protein nor filamin binds to spectrin-depleted erythrocyte membranes.
