Pleiotropic effect due to targeted depletion of secretory rhoptry protein ROP2 in Toxoplasma gondii.
Long after their discovery, the function and biogenesis of rhoptries remain enigmatic. In Apicomplexan parasites, these organelles discharge and their contents are exocytosed at the time of host cell invasion, and are thus proposed to play an essential role in establishing the parasitophorous vacuole. In Toxoplasma gondii, ROP2 is suspected to serve as the molecular link between host cell mitoc...
متن کاملCloning rhoptry protein 1 (ROP1) gene of Toxoplasma gondii (RH) in expression vector
Toxoplasma gondii contain various immunogenic antigens. The most important Toxoplasma antigens are somatic and excreted/secreted antigens. Rhoptry proteins are known as excreted/secreted antigens. These antigens have been proposed as a vaccine candidate against toxoplasmosis. The main objective of the present work was cloning rhoptry protein1 (ROP1) Gene of Toxoplasma gondii (RH) in a cloning...
متن کاملEvaluating the serological applications of Toxoplasma gondii rhoptry protein 1 (ROP1) antigen
Introduction: Toxoplasma gondii (T. gondii) is distributed worldwide and infects most species. The serious incidence and severe or fatal injury caused by T. gondii infection clearly indicates the necessity for the event of a vaccine. The current study goals were to evaluate serological applications of Toxoplasma gondiirhoptry protein 1 (ROP1) ...
متن کاملNovel structural and regulatory features of rhoptry secretory kinases in Toxoplasma gondii.
Serine/threonine kinases secreted from rhoptry organelles constitute important virulence factors of Toxoplasma gondii. Rhoptry kinases are highly divergent and their structures and regulatory mechanism are hitherto unknown. Here, we report the X-ray crystal structures of two related pseudokinases named ROP2 and ROP8, which differ primarily in their substrate-binding site. ROP kinases contain a ...
متن کاملEvaluation of Pichia pastoris-expressed recombinant rhoptry protein 2 of Toxoplasma gondii for its application in diagnosis of toxoplasmosis.
Rhoptry protein 2 (ROP2) of Toxoplasma gondii is a rhoptry-secreted protein that plays a critical role in parasitophorous vacuole membrane formation during invasion. In previous studies, ROP2 has been shown to be efficient in triggering humoral and cell-mediated responses. High immunogenicity of ROP2 makes it a potential candidate for diagnosis and vaccination against toxoplasmosis. In this stu...
