Here I aimed to gain a better understanding of how this regulation is maintained in Toxoplasma at the post-transcriptional level and in the aspect of the formation of messenger ribonucleoprotein complex (mRNPs). I chose to study the poly(A) binding protein (PABP). Metazoans usually encode multiple isoforms of PABP to function in nucleus and/or cytoplasm but in Toxoplasma there is only one predicted PABP. In this thesis, I studied the localization of the only predicted PABP in Toxoplasma (TgPABP). It was detected that TgPABP is predominantly localized in the cytoplasm under treatment with actinomycin D. Second, we also found that TgPABP aggregates into microscopically visible granules, as an indicative of mRNPs.
