PROSITE documentation PDOC00281Glycophorin A signature
Glycophorin A is the major sialoglycoprotein of erythrocyte membrane [1]. Structurally, glycophorin A consists of an N-terminal extracellular domain, heavily glycosylated on serine and threonine residues, followed by a transmembrane region and a C-terminal cytoplasmic domain.
In human there are two closely related forms: glycophorin A which carries the blood group M/N antigen, and glycophorin B which carries the blood group S/s antigen.
The best conserved region of glycophorin A is the transmembrane domain and we have derived a consensus pattern from that region.
