glycophorin

 [gli″ko-for´in]
any of several related proteins that can project through the thickness of the cell membrane of erythrocytes; they attach to oligosaccharides at the outer cell membrane surface and to contractile proteins (spectrin and actin) at the cytoplasmic surface.

glycophorin

[-fôr′in]
one of a group of proteins (A-E) that project through the membrane of red blood cells (RBCs). The outside end of glycophorins A and B carries antigens of the MNS blood group. The sialic acid component of glycophorins contributes to the negative charge of the outer erythrocyte plasma membrane. Influenza virus can attach to sialic acid present on glycophorin A, B, C, D, and E and produce agglutination (does not enter RBCs). Malaria virus can attach to glycophorin A and C and infect RBCs. See also blood group.

glycophorin

a glycopolypeptide found in human erythrocytes.

Phycoerythrin (PE)-labeled monoclonal antibody against human glycophorin A (anti-glycophorin A-RPE) was from Dako (Glostrub, Denmark), and fluo-4 acetoxymethyl ester (Fluo-4 AM) was from Molecular Probes (Eugene, OR, USA).
The most common cause is infection with parvovirus type B19, which infects early erythroid precursors through the glycophorin receptor.
To aid in the interpretations of these stains, we found that glycophorin A (Ventana Medical Systems, Inc, Tucson, Arizona) was an adequate control for erythrocyte staining; CD31 or factor VIII-related antigen (Ventana) were adequate controls for endothelial staining; and E-cadherin (Ventana) was an adequate control for epithelial staining.
They found that the EBA175 protein from chimpanzee specific malaria parasites could bind to human Glycophorin A, thereby ruling out this interaction as a specificity factor.
We assayed the correlation between gene expression levels of VEGF-A or VEGF-C and expression of antigens CD2, CD3, CD4, CD7, CD10, CD11b, CD13, CD14, CD15, CD19, CD20, CD22, CD33, CD34, CD38, CD45, HLA-DR, TdT, and glycophorin A; no significant correlations were found.
The replaced amino acids were located in a refined 3-dimensional computer model of the HAV protomer (11), and their relative distances to residues 1102, 1171 and 1176, constituents of the immunodominant site (12), and to residue 1221, constituent of the glycophorin A binding site epitope (13), were used as markers of the potential antibody-escaping phenotype.
