Scheme of experimental approach and immunoprecipitation experiments. A) Scheme of the experimental approach. For IP, cytosolic cell-free extracts from epimastigotes (Input) were incubated with preimmune serum and anti-TcUBP1 or anti-TcRBP3 antibodies. RNA extracted from immunoprecipitated mRNP complexes was used to perform RT-PCR and to construct a cDNA library. B) Detection of proteins was done by Western blot employing specific antibodies. The position of the bands corresponding to each protein and to the heavy chain (hc) of antibodies is indicated with an arrow on the left side of the panel.
