Specific amino acid residues in the cytoplasmic domain are essential for PfRh4 function. Localization of PfRh4 and PfRh2 in Rh4-WT tail, RH4-AMA1 tail (PfRh4 tail was replaced with the cytoplasmic sequence of AMA1), Rh4-mut4tail ) contains the mutations S1667A, S1674A, Y1680A and Y1684A) and RH4-mut5tail (contains similar mutations with an addition mutation at S1652A within the PfRh4 cytoplasmic tail) lines as detected using anti-PfRh4 monoclonal and anti-PfRh2 polyclonal antibodies. Parasite nuclei were stained with DAPI. Rh4-mut4 tail and Rh4-mut5 tail expressed PfRh4 and all showed an apical localization similar to rhoptry protein PfRh2
