Protein names Glycophorin-A (MN sialoglycoprotein) (PAS-2) (Sialoglycoprotein alpha) (CD antigen CD235a)
Gene names GYPA,GYPA GPA
Protein family Glycophorin A family
Mass 9606Da
Function Component of the ankyrin-1 complex, a multiprotein complex involved in the stability and shape of the erythrocyte membrane (PubMed:35835865). 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.; (Microbial infection) Appears to be a receptor for Hepatitis A virus (HAV).; (Microbial infection) Receptor for P.falciparum erythrocyte-binding antigen 175 (EBA-175); binding of EBA-175 is dependent on sialic acid residues of the O-linked glycans.
Catalytic activity #N/A
Subellular location Cell membrane ; Single-pass type I membrane protein. Note=Appears to be colocalized with SLC4A1.
Structure Homodimer (PubMed:11313283, PubMed:1463744, PubMed:35835865). Component of the ankyrin-1 complex in the erythrocyte, composed of ANK1, RHCE, RHAG, SLC4A1, EPB42, GYPA, GYPB and AQP1 (PubMed:35835865). Interacts with SLC4A1; a GYPA monomer is bound at each end of the SLC4A1 dimer forming an heterotetramer (PubMed:35835865).; (Microbial infection) Interacts with Streptococcus gordonii hsa protein.; (Microbial infection) Interacts (in a sialic acid-independent manner) with P.falciparum MSP1 subunit p83.
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).
