General description

Glycophorin A (GpA) is an important sialoglycoprotein on human red cells. It is one of the best characterized mammalian integral membrane proteins, containing three distinct domains. A large hydrophilic portion carries the NH2-terminal and is positioned on the external surface of the red cell, and the COOH-terminal is found in the cytoplasm. A hydrophobic segment of 23 amino acids (embedded within the lipid bilayer ) connects these two hydrophilic sequences.[1]

Application

Glycophorin A was used to study the Plasmodium falciparum erythrocyte-binding antigen-175 (EBA175)-glycophorin-A interaction.[1]

Biochem/physiol Actions

A membrane glycoprotein with several isoforms that interact with other membrane proteins to confer shape and antigenicity to erythrocytes.
