Investigating The Role Of Rna-Binding Protein 5 In The Life Cycle Differentiation Of Trypanosoma Brucei, David Anaguano Pillajo

Masters Theses

Trypanosomatid parasites such as Trypanosoma brucei have unusual mechanisms of gene expression including polycistronic transcription, mitochondrial RNA editing and trans-splicing. Additionally, these protists rely mainly on post-transcriptional regulation where RNA-binding proteins (RBP) have shown to play a major role. RBP6 and RBP10 are two examples of RBPs that play crucial roles in procyclic and bloodstream form parasites differentiation respectively, by post-transcriptional regulation. Over-expression of RBP6 is enough to promote differentiation into metacyclic trypomastigotes that are infective to mice. However, continuous expression is required, and this pattern does not reflect the natural expression in the tsetse fly or the influence of …
