1 Blood group MN-dependent difference in degree of galactosylation of O-glycans of glycophorin A is restricted to the GalNAc residues located on amino acid residues 2-4 of the glycophorin polypeptide chain. N-acetylgalactosaminuronic acid glycophorin A (MNS blood group) Homo sapiens
2 Glycophorin A (GPA) of human erythrocytes contains a minor number of unsubstituted GalNAc residues (Tn receptors) which are recognized by Moluccella laevis lectin (MLL). N-acetylgalactosaminuronic acid glycophorin A (MNS blood group) Homo sapiens
3 The asialoglycopeptides 1-39 and 1-8 derived from GPA-N showed about 2 and 4 times higher content of non-galactosylated GalNAc residues, respectively, and higher reactivity with MLL than their counterparts derived from GPA-M, while asialoglycopeptides 9-39 of GPA-M and GPA-N did not show such differences. N-acetylgalactosaminuronic acid glycophorin A (MNS blood group) Homo sapiens
4 These results demonstrate that higher expression of non-galactosylated GalNAc in GPA-N than in GPA-M is confined to GalNAc residues located in the amino-terminal portion of GPA polypeptide chain, between the blood group M- and N-specific amino acid residues 1 and 5. N-acetylgalactosaminuronic acid glycophorin A (MNS blood group) Homo sapiens
5 These results demonstrate that higher expression of non-galactosylated GalNAc in GPA-N than in GPA-M is confined to GalNAc residues located in the amino-terminal portion of GPA polypeptide chain, between the blood group M- and N-specific amino acid residues 1 and 5. N-acetylgalactosaminuronic acid glycophorin A (MNS blood group) Homo sapiens
6 These results demonstrate that higher expression of non-galactosylated GalNAc in GPA-N than in GPA-M is confined to GalNAc residues located in the amino-terminal portion of GPA polypeptide chain, between the blood group M- and N-specific amino acid residues 1 and 5.
