Spectrin-based skeleton in red blood cells and malaria.
PURPOSE OF REVIEW Malaria represents one of the most important selective factors affecting human populations. Several inherited diseases of red blood cells lead to resistance at the erythrocytic stage. Among patients who experience hereditary elliptocytosis related to mutations of erythrocyte membrane proteins, molecular studies have shown the prevalence of particular spectrin mutations in pati...
متن کاملEssential control of an endothelial cell ISOC by the spectrin membrane skeleton
Mechanism(s) underlying activation of store-operated Ca2+ entry currents, ISOC, remain incompletely understood. F-actin configuration is an important determinant of channel function, although the nature of interaction between the cytoskeleton and ISOC channels is unknown. We examined whether the spectrin membrane skeleton couples Ca2+ store depletion to Ca2+ entry. Thapsigargin activated an end...
متن کاملDrosophila spectrin: the membrane skeleton during embryogenesis
The distribution of alpha-spectrin in Drosophila embryos was determined by immunofluorescence using affinity-purified polyclonal or monoclonal antibodies. During early development, spectrin is concentrated near the inner surface of the plasma membrane, in cytoplasmic islands around the syncytial nuclei, and, at lower concentrations, throughout the remainder of the cytoplasm of preblastoderm emb...
متن کاملMutations in the murine erythroid α-spectrin gene alter spectrin mRNA and protein levels and spectrin incorporation into the red blood cell membrane skeleton
Tetramers of αand β-spectrin heterodimers, linked via intermediary proteins to transmembrane proteins, stabilize the red blood cell cytoskeleton. Deficiencies of either αor β-spectrin can result in severe hereditary spherocytosis or elliptocytosis (HS/HE) in mice and humans. Four mouse mutations, sph, sph, sph, and sph, affect the erythroid αspectrin gene, Spna1, on Chromosome 1 and cause sever...

Tetramers of alpha- and beta-spectrin heterodimers, linked by intermediary proteins to transmembrane proteins, stabilize the red blood cell cytoskeleton. Deficiencies of either alpha- or beta-spectrin can result in severe hereditary spherocytosis (HS) or hereditary elliptocytosis (HE) in mice and humans. Four mouse mutations, sph, sph(Dem), sph(2BC), and sph(J), affect the erythroid alpha-spect...
