Band 3-glycophorin A association in erythrocyte membranes demonstrated by combining protein diffusion measurements with antibody-induced cross-linking

Abstract: A new approach to the study of molecular protein interactions in biological membranes is presented. The technique is based on measuring the rotation of a membrane protein in the presence and absence of specific antibodies directed toward a purported complex partner. As a first illustration of the method, the putative association of band 3 with glycophorin A in the human erythrocyte membrane was investigated. The rotational diffusion of band 3 was strongly reduced following cross-linking of glycophorin A with d… Show more

“…Whether the MSP1-band 3 interaction plays a primary role in a dominant sialic acid-independent invasion pathway across P. falciparum lines remains to be seen. Association between band 3 and GPA in the human RBC membrane has been shown (44,45). In this regard, an RBC invasion mechanism in which the parasites use band 3 and GPA in a cooperative or complementary manner could be possible.…”

“…To date, there are several studies that suggest how glycophorin A may associate with the skeletal proteins. Nigg et al (41) performed protein rotational diffusion measurements, which suggest a noncovalent association of the intramembranous portion of glycophorin A with that of band 3. Because band 3 is known to bind to protein 2.1, which in turn is bound to spectrin, it is possible that it is through this band 3 association that glycophorin A affects the skeleton.…”

“…Abundant evidence implicates the RBC membrane skeleton in controlling band 3 lateral mobility. Disruption of spectrin-ankyrin and ankyrin-band 3 linkages causes band 3 mobility to increase (21)(22)(23)(24), as does treatment with proteases to remove the cytoplasmic domain of band 3 (25,26) or treatment with ATP or 2,3-DPG (27) at levels that are sufficient to destabilize isolated RBC membrane skeletons (28) Band 3 rotational mobility has been studied in normal RBC ghosts (26,(34)(35)(36)(37)(38)(39)(40)(41)(42)(43)(44), abnormal RBC ghosts (45,46), and intact RBCs (19,31,37).2 Rapidly rotating, slowly rotating, and rotationally immobile forms of band 3 appear to coexist in the membrane. At 37°C in normal RBC membranes, 20-25% of band 3 molecules rotate with correlation times (r) < 250 Ms, 50-75% rotate with r 1-3 ms, and 5-25% are rotationally immobile on the time scale of the experiment (19,37,40 About half of the rapidly rotating band 3 molecules may rotate with correlation times of 25-30 ,ts; this population could represent band 3 dimers rotating free of constraints other than the viscosity of the lipid bilayer (37).…”
