Ankyrin-bound fatty acid turns over rapidly at the erythrocyte plasma membrane.

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.
