Several Maurer's clefts resident proteins have been identified for P. falciparum, such as MAHRP1 [34], SBP1 [35], REX1 and REX2 [36], [37] and members of the PfMC-2TM protein family [24] but no obvious orthologues have been described for the rodent malaria parasites. This evidence concerns the gene REXO2 and malaria.
