PF3D7_0936000 ring-exported protein 2

The hyp11 protein encoded by PFA0610c is an exported protein with a non-canonical PEXEL/HT. A. Fluorescence microscopy. The schematic structure of the GFP-tagged proteins is depicted on the left of representative images of iRBCs.The ER-signal is shaded blue, the (non-) canonical PEXEL/HT is shaded black and GFP is shaded green. Putative cleavage sites are indicated by an arrow (blue: SP cleavage site; black: Plasmepsin V cleavage site. B. Immunofluorescence analyses. Antibodies against GFP and the Maurer’s clefts protein were used. Membranes were stained with Bodipy-TR-C5ceramide. The fluorescence of GFP-tagged PFA0610c (01128-RIIAE-GFP), a protein with a R.I.E variant, appeared to be located close to the RBC membrane (A). 01128-RIIAE-GFP did not colocalize with REX2 (B).This indicates that PFA0610cis associated with the RBC membrane.
