引用 | ジャーナル: Nat Struct Mol Biol / 年: 2022タイトル: Architecture of the human erythrocyte ankyrin-1 complex. 著者: Francesca Vallese / Kookjoo Kim / Laura Y Yen / Jake D Johnston / Alex J Noble / Tito Calì / Oliver Biggs Clarke / ![]() 要旨: The stability and shape of the erythrocyte membrane is provided by the ankyrin-1 complex, but how it tethers the spectrin-actin cytoskeleton to the lipid bilayer and the nature of its association ...The stability and shape of the erythrocyte membrane is provided by the ankyrin-1 complex, but how it tethers the spectrin-actin cytoskeleton to the lipid bilayer and the nature of its association with the band 3 anion exchanger and the Rhesus glycoproteins remains unknown. Here we present structures of ankyrin-1 complexes purified from human erythrocytes. We reveal the architecture of a core complex of ankyrin-1, the Rhesus proteins RhAG and RhCE, the band 3 anion exchanger, protein 4.2, glycophorin A and glycophorin B. The distinct T-shaped conformation of membrane-bound ankyrin-1 facilitates recognition of RhCE and, unexpectedly, the water channel aquaporin-1. Together, our results uncover the molecular details of ankyrin-1 association with the erythrocyte membrane, and illustrate the mechanism of ankyrin-mediated membrane protein clustering. | ||||||

The sample was sonicated using microprobe (amplitude = 30, pulse on = 5 sec, rest time = 10 sec, total pulse on = 50 sec). Large fragments are removed by centrifugation (6,000 x g, 10 minutes) and the supernatant was extruded (Avanti Polar Lipid) 10 times using a 400 nm filter. After extrusion, vesicles were collected by ultra-centrifugation at 35,000 rpm for 30 minutes (S120-AT3, Sorvall). The pellet, which contains vesicles, was resuspended at a final concentration of 5 mg/mL. All steps were performed at room temperature to facilitate vesicle formation. |
