HECT ubiquitin-protein ligase (PfUT) localizes to the ER/Golgi complex. Right panels: Subcellular localization of PfUT by immunoelectron microscopy. The upper panel shows a representative micrograph of a P. falciparum-infected erythrocyte preserved by high-pressure freezing and freeze-substitution, and immunolabelled with a rabbit antiserum specific to the N-terminal domain of PfUT coupled to 10 nm protein A colloidal gold. The lower panel shows the surface rendered view of the micrograph, with red dots representing gold grains. Left: Magnification of boxed section in micrograph. Arrowheads point towards gold label. n, nucleus; fv, food vacuole. Scale bar in D and E, 500 nm. Quantitative immunoelectron microscopy confirmed a predominant localization of PfUT at the ER/Golgi complex.
