The presence of duffy-binding-like domains defines the family of erythrocyte binding-like proteins (EBL), a family of cell invasion proteins universal among Plasmodium. These other members may use some other receptor, for example Glycophorin A. The other universal invasion protein is reticulocyte binding protein homologs.[3] Both families are essential for cell invasion, as they function cooperatively.[4]
