Organellar dynamics during the cell cycle of Toxoplasma gondii
The protozoan phylum Apicomplexa encompasses ∼5000 species of obligate intracellular parasites, including those responsible for malaria and toxoplasmosis. Rather than dividing by binary fission,… Expand
Dynamics of Toxoplasma gondii Differentiation

- 1 August 2004
ABSTRACT Parasite differentiation is commonly associated with transitions between complex life cycle stages and with long-term persistence in the host, and it is therefore critical for pathogenesis.… Expand
The Motility of a Human Parasite, Toxoplasma gondii, Is Regulated by a Novel Lysine Methyltransferase

- Biology, Medicine
- PLoS pathogens
- 1 September 2011
Protozoa in the phylum Apicomplexa are a large group of obligate intracellular parasites. Toxoplasma gondii and other apicomplexan parasites, such as Plasmodium falciparum, cause diseases by… Expand
Multiple Functionally Redundant Signals Mediate Targeting to the Apicoplast in the Apicomplexan Parasite Toxoplasma gondii

ABSTRACT Most species of the protozoan phylum Apicomplexa harbor an endosymbiotic organelle—the apicoplast—acquired when an ancestral parasite engulfed a eukaryotic plastid-containing alga. Several… Expand
Structure and developmental expression of Strongyloides stercoralis fktf-1, a proposed ortholog of daf-16 in Caenorhabditis elegans.

- 1 November 2003
A forkhead transcription factor gene, fktf-1, which we propose to be orthologous to the Caenorhabditis elegans dauer-regulatory gene daf-16 has been discovered in the parasitic nematode Strongyloides… Expand
Isolation and characterization of TgVP1, a type I vacuolar H+-translocating pyrophosphatase from Toxoplasma gondii. The dynamics of its subcellular localization and the cellular effects of a…

- 10 January 2003
Here we report the isolation and characterization of a type I vacuolar-type H(+)-pyrophosphatase (V-PPase), TgVP1, from an apicomplexan, Toxoplasma gondii, a parasitic protist that is particularly… Expand
SNAIL SPEARS AND SCIMITARS: A CHARACTER ANALYSIS OF CONUS RADULAR TEETH
Knowledge of the attributes of the venom-injecting radular teeth of Conus can enhance understanding of the functional biology of feeding and the systematics of this large and taxonomically difficult… Expand
Differential Localization of Alternatively Spliced Hypoxanthine-Xanthine-Guanine Phosphoribosyltransferase Isoforms in Toxoplasma gondii*

- Biology, Medicine
- Journal of Biological Chemistry
- 10 June 2005
A unique feature of the Toxoplasma gondii purine salvage pathway is the expression of two isoforms of the hypoxanthine-xanthine-guanine phosophoribosyltransferase (HXGPRT) of the parasite encoded by… Expand
Requirement of the single base insertion at the 3' end of the env-related gene of Friend spleen focus-forming virus for pathogenic activity and its effect on localization of the glycoprotein product…

In order to obtain evidence for the essential role of the single base insertion occurring at the 3' end of the env-related gene of Friend spleen focus-forming virus (SFFV) encoding the leukemogenic… Expand
A Novel GDP-dependent Pyruvate Kinase Isozyme from Toxoplasma gondii Localizes to Both the Apicoplast and the Mitochondrion*
We previously reported a cytosolic pyruvate kinase (EC 2.7.1.40) from Toxoplasma gondii (TgPyKI) that differs from most eukaryotic pyruvate kinases in being regulated by glucose 6-phosphate rather… Expand
