Phosphoinositides, kinases and adaptors coordinating endocytosis in Trypanosoma brucei.
In the kinetoplastid parasite Trypanosoma brucei clathrin-mediated endocytosis is essential for survival and aids immune evasion in the mammalian host. The formation of endocytic clathrin coated vesicles in T. brucei is via a unique mechanism owing to an evolutionarily recent loss of the adaptor protein (AP)2 complex, a central hub in endocytic vesicle assembly. Despite this loss, recent studie...
متن کاملClathrin-mediated endocytosis is essential in Trypanosoma brucei.
In Trypanosoma brucei, the plasma membrane is dominated by glycosylphosphatidylinositol (GPI)-anchored proteins. Endocytic activity correlates with expression levels of the clathrin heavy chain TbCLH, and additional evidence suggests that rapid endocytosis may play a role in evasion of the immune response. TbCLH is present on both endocytic vesicles and post-Golgi elements, suggesting a similar...
متن کاملTrypanosoma brucei brucei
Protein synthesis in Trypanosoma brucei brucei was rapidly inhibited during polyamine depletion by DL-adifluoromethylornithine (DFMO) in vitro and in vivo. [3H]Leucine incorporation was depressed 30-40 % by 24 h and 80-90 % by 48 h of DFMO treatment. Concomitantly there was an apparent decrease in the synthesis of the variant-specific glycoprotein (VSG) in DFMO-treated trypanosomes, as measured...
متن کاملProtein isoprenylation in Trypanosoma brucei brucei.
Trypanosoma brucei is a digenetic protozoan parasite presenting a public health hazard in certain areas of Africa; it is transmitted between mammals (bloodstream form (BSF)) by tsetse flies (procyclic form (PCF)). We have an ongoing interest in small GTP proteins in T. brucei, and these are commonly isoprenylated. Many isoprenylated proteins belong to the rab family and include ras; the isopren...
متن کاملSUMOylation in Trypanosoma brucei
Small ubiquitin like modifier (SUMO) proteins are involved in many processes in eukaryotes. We here show that Trypanosoma brucei SUMO (Tb927.5.3210) modifies many proteins. The levels of SUMOylation were unaffected by temperature changes but were increased by severe oxidative stress. We obtained evidence that trypanosome homologues of the SUMO conjugating enzyme Ubc9 (Tb927.2.2460) and the SUMO...
