Abstract (Russian): This study examines the action of hypoxia on integrity, fluidity and protein composition of red blood cell (RBC) membrane. Twenty-min exposure to oxygen-free environment decreases rat RBC integrity documented by 3-fold elevation of hemoglobin release without any action on the membrane fluidity estimated by electron magnetic resonance spectroscopy of spin-labeled stearic acid analogues. The proteomics technology in combination with relative label free quantification analysis revealed a dozen of membrane-bound proteins, including elevated content of hemoglobin, reproducibly affected by hypoxia. Mapping the identified proteins in the KEGG pathway database we found that the proteins of multi subunit Cullin-Rbx E3 ubiquitin ligase complex are presented in normoxic RBC ghosts but not in the hypoxic samples. Our results suggest that Cullin-Rbx E3 complex, associated with RBC membrane in normoxia, provides detection and deletion of membrane proteins damaged by reactive oxygen species. In hypoxic conditions, deoxy-Hb binds to band 3 protein, resulting in dissociation of Cullin-Rbx E3 complex from RBC membrane and impaired clearance of damaged cytoskeleton proteins. These rearrangements of membrane proteins might be involved in attenuated membrane integrity revealed in hypoxic RBC. Significance This study demonstrate that sustained deoxygenation of rat erythrocytes alters the composition of membrane-bound proteins including elevation of the content of hemoglobin without any changes in the viscosity of erythrocyte membrane lipid bilayer. These results suggest that the changes the composition of membrane proteins result in attenuated membrane integrity and contribute to augment release of hemoglobin seen in hypoxic conditions.
