Resources:FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT

Disease

[RHCE_HUMAN] Rh deficiency syndrome. The disease is caused by variants affecting the gene represented in this entry.

Function

[RHCE_HUMAN] May be part of an oligomeric complex which is likely to have a transport or channel function in the erythrocyte membrane.

Publication Abstract from PubMed

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.
