Thermal proteome profiling of Toxoplasma gondii treated with enhancer 1 (ENH1)

ABSTRACT: reviously, we characterized a chemical modulator, ENH1, that exhibited potent antiparasitic properties against apicomplexans and induced calcium oscillations, but the target eluded identification. To determine the target of ENH1, we employed thermal proteome profiling in parasites. We treated extracellular parasites with vehicle (DMSO) or ENH1 for 15 minutes at 37°C, under conditions previously determined to induce calcium fluxes in T. gondii.8 Parasites were then heated at 10 different temperatures to induce thermal denaturation. Following lysis and high-speed centrifugation, soluble protein was isolated and analyzed by mass spectrometry to generate thermal stability profiles from each condition across two biological replicates.
