Recombinant Human Glycophorin-A (GYPA GPA MNS)

1. 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. PMID: 28980921

3. The authors show that Plasmodium falciparum EBA-175 mediates substantial changes in the deformability of erythrocytes by binding to glycophorin A and activating a phosphorylation cascade that includes erythrocyte cytoskeletal proteins resulting in changes in the viscoelastic properties of the host cell. PMID: 28226242
4. 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. PMID: 27580023
5. CD235a could be the most sensitive predictor similar to CD4. PMID: 25716234
6. 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. PMID: 26239059
7. 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. PMID: 25628009
8. GPA-deficient band 3 null erythrocytes are resistant to malaria infection. PMID: 25778531
9. MNSs blood group glycophorin variants in Taiwan: a genotype-serotype correlation study of 'Mi(a)' and St(a) with report of two new alleles for St(a). PMID: 24858913
10. PfEBA-175 engages multiple glycans of GpA encoded by exon 3 and that the presentation of glycans is likely required for high-avidity binding. PMID: 25205096
11. The expression of glycophorin A and osteoprotegerin is locally increased in carotid atherosclerotic lesions of symptomatic compared to asymptomatic patients. PMID: 23722820
12. These data demonstrate the importance of PfEBA175 regions other than the DBL domains in the interaction with GYPA and merit their inclusion in an EBA175-based vaccine. PMID: 24043627
13. GPA-NN mutagens contributed to the pathogenesis of chronic benzene poisoning. PMID: 17456399
14. Beta-branched residues adjacent to GG4 motifs promote the efficient association of glycophorin A transmembrane helices. PMID: 21072853
15. 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. PMID: 21455273
16. the GG genotype of the rs 1489759 HHIP single-nucleotide polymorphism (SNP) and the CC genotype of the rs 2202507 GYPA SNP confers a ''protective'' effect on COPD (OR 0.59, p50.006 for HHIP and OR50.65, p50.006 for GYPA) and lung cancer. PMID: 21119205
17. Data indicate that changes of the glycophorin A dimerization propensities in different lipid bilayers suggest that the lipid bilayer thickness severely influences the monomer-dimer equilibrium of the transmembrane domain. PMID: 20603102
18. ABH blood group antigens in N-glycan of human glycophorin A. PMID: 20434428
19. The Sta gene found in this family has A246 & C252, C302, and G307. The putative crossing-over point is between nucleotides 252 to 302 in Intron 3. PMID: 20233359
20. 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. PMID: 20074546
21. 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. PMID: 19907019
22. Natural selection of polymorphisms/variants on the erythrocyte surface PMID: 11861881
23. Somatic cell mutations found at the gene locus in erythrocytes of radiation workers at a nuclear facility PMID: 12492375
24. Distinct regions of human glycophorin A enhance human red cell anion exchanger transport function and surface trafficking PMID: 12813056
25. 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 PMID: 14604989
26. Porcine Kupffer cells bind xenogeneic human RBC by recognition of a carbohydrate epitope on glycophorin A. PMID: 16003235
27. This study demonstrates the systematic classification of ten alleles (five M and five N alleles) of the MN blood group system to major or minor variations of the standard alleles. PMID: 16205834
28. glycophorin A somatic mutation frequency levels in newborns are not related to maternal lifestyle factors or drug metabolizing enzyme genotypes PMID: 16424825
29. GYPA & GYPB genotypes carrying MNSs antigens were analyzed in Thai patients with cerebral malaria & mild malaria; no statistical difference was found; it is concluded that MNSs antigens do not reveal the difference in susceptibility to cerebral malaria PMID: 17372674
30. single mutations in glycophorin A can result in the observed fourth power relationship with age of oncet in polycythemia rubra vera PMID: 17452518
31. 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. PMID: 19071041
