  • Title: Ankyrin-bound fatty acid turns over rapidly at the erythrocyte plasma membrane.
    Author: Staufenbiel M.
    Journal: Mol Cell Biol; 1987 Aug; 7(8):2981-4. PubMed ID: 2959856.
    Abstract:
    The membrane skeletal protein ankyrin was shown to be continuously acylated and deacylated with long-chain fatty acids in mature erythrocytes. At least a fraction of the lipid bound to ankyrin turned over rapidly (half-life, approximately 50 min) compared with the polypeptide backbone, which was stable throughout the erythrocyte life. This indicates a regulatory significance of the fatty acid modification for the function of ankyrin.
