NCBI Description
Glycophorins A (GYPA) and B (GYPB) are major sialoglycoproteins of the human erythrocyte membrane which bear the antigenic determinants for the MN and Ss blood groups. In addition to the M or N and S or s antigens that commonly occur in all populations, about 40 related variant phenotypes have been identified. These variants include all the variants of the Miltenberger complex and several isoforms of Sta, as well as Dantu, Sat, He, Mg, and deletion variants Ena, S-s-U- and Mk. Most of the variants are the result of gene recombinations between GYPA and GYPB. [provided by RefSeq, Jul 2008]
Uniprot Description
Function: Glycophorin A is the major intrinsic membrane protein of the erythrocyte. The N-terminal glycosylated segment, which lies outside the erythrocyte membrane, has MN blood group receptors. Appears to be important for the function of SLC4A1 and is required for high activity of SLC4A1. May be involved in translocation of SLC4A1 to the plasma membrane. Is a receptor for influenza virus. Is a receptor for Plasmodium falciparum erythrocyte-binding antigen 175 (EBA-175); binding of EBA-175 is dependent on sialic acid residues of the O-linked glycans. Appears to be a receptor for Hepatitis A virus (HAV). Ref.21 Ref.23 Ref.26 Ref.29 Ref.30 Ref.32
Subunit structure: Homodimer. Interacts with Streptococcus gordonii hsa protein. Ref.19 Ref.24 Ref.31
Subcellular location: Cell membrane; Single-pass type I membrane protein. Note: Appears to be colocalized with SLC4A1. Ref.25
Post-translational modification: The major O-linked glycan are NeuAc-alpha-(2-3)-Gal-beta-(1-3)-[NeuAc-alpha-2-6]-GalNacOH (about 78 %) and NeuAc-alpha-(2-3)-Gal-beta-(1-3)-GalNAcOH (17 %). Minor O-glycans (5 %) include NeuAc-alpha-(2-3)-Gal-beta-(1-3)-[NeuAc-alpha-2-6]-GalNAcOH NeuAc-alpha-(2-8)-NeuAc-alpha-(2-3)-Gal-beta-(1-3)-GalNAcOH. About 1% of all O-linked glycans carry blood group A, B and H determinants. They derive from a type-2 precursor core structure, Gal-beta-(1,3)-GlcNAc-beta-1-R, and the antigens are synthesized by addition of fucose (H antigen-specific) and then N-acetylgalactosamine (A antigen-specific) or galactose (B antigen-specific). Specifically O-linked-glycans are NeuAc-alpha-(2-3)-Gal-beta-(1-3)-GalNAcOH-(6-1)-GlcNAc-beta-(4-1)-[Fuc-alpha-1-2]-Gal-beta-(3-1)-GalNAc-alpha (about 1%, B antigen-specific) and NeuAc-alpha-(2-3)-Gal-beta-(1-3)-GalNAcOH-(6-1)-GlcNAc-beta-(4-1)-[Fuc-alpha-1-2]-Gal-beta (1 %, O antigen-, A antigen- and B antigen-specific).
Polymorphism: Along with GYPB, GYPA is responsible for the MNS blood group system. The molecular basis of the GPA M/N bloodgroup antigen is a variation at positions 20 and 24. Ser-20 and Gly-24 correspond to M (shown); 'Leu-20' and 'Glu-24' correspond to N.GYPA polymorphisms are involved in resistance to malaria [
MIM:611162].
Miscellaneous: Involved in several unequal homologous recombinations or gene conversion events, predominantly with GYPB and more rarely with GYPE. The resulting fusion proteins are observed in different phenotypes and encode low incidence bloodgroup antigens.
Sequence similarities: Belongs to the glycophorin A family.
Sequence caution: The sequence AAA52624.1 differs from that shown. Reason: Erroneous initiation.

Product Notes
The GYPA gypa (Catalog #AAA524006) is an Antibody produced from Rabbit and is intended for research purposes only. The product is available for immediate purchase. The Anti-human Glycophorin A, Purified (Polyclonal) (rabbit IgG) reacts with Human and may cross-react with other species as described in the data sheet. AAA Biotech's Glycophorin A can be used in a range of immunoassay formats including, but not limited to, Immunohistochemistry (IHC). Researchers should empirically determine the suitability of the GYPA gypa for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "Glycophorin A, Polyclonal Antibody" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
