Spectrin and ankyrin participate in membrane organization, stability, signal transduction, and protein targeting; their interaction is critical for erythrocyte stability. Repeats 14 and 15 of betaI-spectrin are crucial for ankyrin recognition, yet the way spectrin binds ankyrin while preserving its repeat structure is unknown. We have solved the crystal structure of the betaI-spectrin 14,15 di-repeat unit to 2.1 A resolution and found 14 residues critical for ankyrin binding that map to the end ...[more]
