PF3D7_1001400 exported lipase 1

Four a/b-hydrolases are exported into the erythrocyte compartment. Immunofluorescence assay (IFA) of trophozoite/early schizont-stage parasites overexpressing GFP-tagged a/b-hydrolases. Parasites were fixed with paraformaldehyde/glutaraldehyde and stained with anti-GFP (green). The nuclei were stained with 4’,6’-iamidino-2-phenylindole (DAPI) (blue). (A) PfEH1-GFP, (B) PfEH2-GFP, (C) PfXL1-GFP, and (D) PfXL2-GFP. Expression was under control of the constitutive HSP86 promoter. The images are representative of at least three independent experiments. Bars=5 mm. DIC, differential interference contrast. For the two a/b-hydrolase familyA members, fluorescence was observed at the periphery of the infected erythrocyte and within the parasite (A and B). In contrast, for the two family B members, fluorescence was diffuse throughout the cytosol of the infected RBC (C and D).
