Diagnostic value of glycophorin-A in comparison with P57 immunohistochemical staining method in differentiating complete and partial molar pregnancies.
Cell viability and surface expression of transferrin receptor (CD71) and glycophorin A (GPA) were analyzed before and after re-culture by flow cytometry. These studies show differential sensitivities of these surface proteins on K562 cells to proteases and suggest molecular mechanisms of transmembrane protein transport and cycling.
While weak interactions between glycophorin and band 3 undoubtedly exist glycophorin A and band 3 must have separate interactions in the membrane that control their lateral mobility.
Glycophorin-A-rich microparticles are released from evolving growing thrombi into the distal perfusing blood and can be measured in peripheral blood. CD235a(+) cMPs may constitute a novel systemic biomarker of ongoing thrombosis.
The authors demonstrate that the initial vacuolar membrane around internalized Babesia divergens is formed from protein and lipid components of the red blood cells plasma membrane including band 3 glycophorin A and spectrin.
Data suggest that glycophorin A (Gpa) increases expression and activity of Cl-/HCO3- exchanger Ae1 that G719D mutation renders Ae1 mutant constructs GPA-unresponsive and suggests a role for Ae1 amino acids 22-28 in GPA responsiveness.
Energy transfer between differently labelled glycophorin A transmembrane helices decreased with increasing Sodium Dodecyl Sulfate mole fractions albeit without modifying the helicity of the peptides.
Heterozygous missense mutation E758K in the human AE1/SLC4A1/band 3 gene in two unrelated patients with well-compensated hereditary spherostomatocytic anemia induces glycophorin A-independent endogenous cation transport.
GPA depletion does not alter band 3's native conformation at the DIDS binding site. It modulates a conformational equilibrium between 2 states of the binary complex formed by the competitive inhibitor DIDS reversibly bound to properly folded band 3.
Associated with PHARMACOGENOMIC: benzene toxicity., Observational study of gene-disease association. (HuGE Navigator); GPA-NN mutagens contributed to the pathogenesis of chronic benzene poisoning.
band 3 in the red cell can take up two different structures: one with high anion transport activity when glycophorin A is present and one with lower anion transport activity when glycophorin A is absent
