\"Conditional deletion of PfVP1 leads to delayed ring stage development and a complete blockage of the ring-to-trophozoite transition, which can be partially rescued by Arabidopsis thaliana vacuolar pyrophosphatase 1, but not by the soluble pyrophosphatase from Saccharomyces cerevisiae. \"

Imaging data (from Malaria Metabolic Pathways)

Indirect immunofluorescence analysis of V-H+-PPase in trophozoites of P. falciparum. Fluorescence (A, B, C) or bright field (D, E, F) images of infected erythrocytes: A,D, with preimmune serum; B,E, with antibody 324; C,F, with antibody 326. The images show intense labeling over the whole parasites and bright, intracellular spots. Arrows show trophozoite stages of the parasite. Bars=10 mm. Immunofluorescence showed a general fluorescence over the whole parasites and intracellular bright spots suggesting a vesicular and plasma membrane localization.

Immunohistochemical detection of PfNSF. (B), PfNSF in noninfected erythrocyte (C), vacuolar H1-ATPase subunit PF13_0065 A (V-ATPase) (D), H1-pumping pyrophosphatase (V-PPase) PF14_0541 (E), and the serine repeat antigen protein (F) in parasitized erythrocytes. The parasitized erythrocytes were immunostained with the indicated antibodies and then observed by fluorescence microscopy. Vital staining with C5-ceramide was also performed to reveal localization of the tubovesicular membrane networks (TVM) (G). P, P. falciparum cell; EMP, erythrocyte plasma membrane. Bar, 5 mm. the PfNSF immunoreactivity was present within the vesicular structures outside the parasite cells (B). No such extraparasitized vesicular structures were observed in the immunoreactivities against antibodies for vacuolar H+-ATPase (D), H+-pumping pyrophosphatase (E), serine repeat antigen protein, markers for the peripheral space between the parasitophorus vacuolar membranes, and the plasma membrane of the malaria parasite (F).Hayashi M, Taniguchi S, Ishizuka Y, Kim HS, Wataya Y, Yamamoto A, Moriyama Y.
