Polymorphism
The sequence varies across Plasmodium strains (PubMed:2090943).
All variants share conserved N- and C-terminal regions; however, they belong to two allelic families, represented by 3D7 strain and FC27 strain sequences respectively, distinguished by tandem repeats and dimorphic flanking sequences within the central region of the protein (PubMed:2090943).
