  • Title: Effect of anti-spectrin antibody and ATP on deformability of resealed erythrocyte membranes.
    Author: Nakashima K, Beutler E.
    Journal: Proc Natl Acad Sci U S A; 1978 Aug; 75(8):3823-5. PubMed ID: 278995.
    Abstract:
    Deformability of resealed erythrocyte membranes was measured by using an ektacytometer. Divalent anti-spectrin antibody, but not monovalent anti-spectrin Fab fragments, decreased membrane deformability. Membranes resealed with MgATP were more deformable than those without MgATP. Exogenous alkaline phosphatase, which dephosphorylates spectrin, decreased membrane deformability. These results suggest that spectrin is an essential component of the system that determines erythrocyte deformability. They are consistent with the view that the role of ATP in membrane deformability is mediated through phosphorylation of the spectrin.
