Spectrin is the major constituent of the cytoskeletal network underlying the erthrocyte plasma membrane and determines cell shape, arrangement of transmembrane proteins and organization of organelles. It is expressed at very low levels in many tissues, with the strongest expression in the cerebellum, spinal cord, stomach, pituitary gland, liver, pancreas, salivary gland, kidney, bladder and heart (1). Spectrin B 4 is a non-erythrocyte member, and is expressed in the brain and pancreatic islets and localisted to the nuclear matrix, cytoplasmic vesicles and PML nuclear bodies. B4 spectrins are also essential for membrane stability and the molecular organization of the nodes of Ranvier (2).
