Trypanosoma brucei is a deadly kinetoplastid parasite that causes the human and veterinarian diseases African sleeping sickness and nagana. We combine chemical cross-linking and mass spectrometry, structural modeling, genetics, and biochemistry to define the global architecture of RNA editing ?editosome? complexes in these parasites. Editosomes are unique to kinetoplastids, which also include Trypanosoma cruzi and Leishmania parasites that cause Chagas disease and Leishmaniases, respectively. Editosomes are essential for parasite viability and are promising drug targets. This work creates a comprehensive, highly detailed map of editosome protein proximities and interactions, and furthers our understanding of editosome protein function in T. brucei and other kinetoplastids, thus aiding the potential development of new therapeutics for the treatment of several different parasitic diseases.
