PROSITE documentation PDOC51069GBP repeat profile
Interactions between Plasmodium falciparum merozoite and erythrocyte proteins are essential for the parasite's survival. One of the erythrocyte binding proteins is the gylcophorin binding protein (GBP-130), which contains 11 highly conserved 50-residue-long repeats. The GBP repeats have been shown to bind to the erythrocyte receptor glycophorin. It appears that a minimum of between 3.5 and 4.5 repeats is required for the protein to bind to the glycophorin matrix. A correlation between glycophorin binding and repeat number might exist. GBPH is a Plasmodium protein highly homologous to GBP-130. It carries only 8 repeats of 40 residues, which can be superimposed on amino acids 2-41 of the GBP repeats [1,2,3].
The profile we developed covers the entire GBP repeat.
