The Glycophorin A (GPA) is a single pass membrane sialoglycoprotein expressed across the mature erythrocytes and erythroid precursor cells. The sialic acid in glycophorin A contributes to the generation of a net negative surface charge that minimizes interactions between red blood cells and prevents aggregation. It is the carrier of blood group M and N specificities. Glycophorin A acts as a receptor for Sandei virus, parvovirus, and Hsa, and Streptococcus adhesion. Anti-glycophorin A is used in identifying cells of the erythroid lineage.
