Investigating The Role Of Rna-Binding Protein 5 In The Life Cycle Differentiation Of Trypanosoma Brucei, David Anaguano Pillajo Oct 2018

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 …


14-3-3 Protein Rad24 And Its Effect On Mid1 Localization And Contractile Acto- Myosin Ring Assembly During Cytokinesis In S. Pombe, Anissa P. Grawe Aug 2018

14-3-3 Protein Rad24 And Its Effect On Mid1 Localization And Contractile Acto- Myosin Ring Assembly During Cytokinesis In S. Pombe, Anissa P. Grawe

Masters Theses

In animal and yeast cells, cell division (cytokinesis) is facilitated by the formation of a contractile acto-myosin ring (CAR). Proper CAR formation and constriction is heavily reliant on the temporal regulation, phosphorylation, and localization of key proteins. In the fission yeast S. pombe, Mid1 is an important dimeric CAR scaffolding protein that connects the contractile apparatus to the plasma membrane at the right place and time during cytokinesis. Mid1 is confined to both the nucleus and protein assemblies called nodes during interphase, and transitions to the cell cortex at mitotic entry as nodes mature and coalesce into the CAR. Rad24 …
