Abstract:
This report describes the molecular characterization of the Tc8.2 gene of Trypanosoma cruzi. Both the Tc8.2 gene and its encoded protein were analyzed by bioinformatics, while Northern blot and RT-PCR were used for the transcripts. Besides, immunolocalization of recombinant protein was done by immunofluorescence and electron microscopy. Analysis indicated the presence of a single copy of Tc8.2 in the T. cruzi genome and 2-different sized transcripts in epimastigotes/amastigotes and trypomastigotes. Immunoblotting showed 70 and 80 kDa polypeptides in epimastigotes and trypomastigotes, respectively, and a differential pattern of immunolocalization. Overall, the results suggest that Tc8.2 is differentially expressed during the T. cruzi life cycle.
