[Term] id: PR:000001352 name: glycophorin def: "A protein that contains an extracellular Glycophorin A domain (Pfam:PF01102), followed by a single-pass transmembrane region and a small intracellular domain. A protein that is an integral protein of the red cell membrane. Proteins in this class are responsible for the molecular basis of the blood group antigens, surface markers on the outside of the red blood cell membrane."
