MTRAP is a micronemal protein. Upper panel: immunofluorescence microscopy shows apical concentration of MTRAP different to that of PfRAP1, a known basal rhoptry protein. Lower panel, immunoelectron microscopy confirms that apical localization is to the micronemes. m, microneme; R, rhoptry. The arrows indicate concentrations of immunogold labeling against MTRAP-TSR.
