Glycophorin A is the major intrinsic membrane sialoglycoprotein of the erythrocyte. 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.

Data suggest that glycophorin A (Gpa) increases expression and activity of Cl-/HCO3- exchanger Ae1, that G719D mutation renders Ae1 mutant constructs GPA-unresponsive, and suggests a role for Ae1 amino acids 22-28 in GPA responsiveness.PMID:21455273

The resistance of glycophorin A knockout mice against infection with the OB1 variant of Babesia rohaini may be attributed to the effective clearance of the parasitized erythrocytes lacking GPA in the spleen.PMID:19084340
