The C. Elegans Rna-Binding Protein Gld-1 Recognizes Sequence, Structure And Context Information To Repress Translation Of Its Mrna Targets, Jung Hoon Doh
Legacy Theses & Dissertations (2009 - 2024)
Considering the general suppression of transcription during late oogenesis and early embryo development, post-transcriptional control of maternal mRNAs by RNA binding proteins emerges as an important mechanism in controlling late oogenesis and early embryo development. The C. elegans germline offers an ideal system to understand such processes. GLD-1 (GermLine Development defective) is a maxi-KH motif containing RNA binding protein, which controls many different stages during the C. elegans germline development from decision over germ cell proliferation vs. meiosis entry to production of mature gametes, suggesting that GLD-1 likely controls many mRNA targets. gld-1 mutants have variable germline defects, the major …

The Role Of An Rna Binding Protein Hnrnp K During Axon Development And Regeneration In Xenopus Laevis, Yuanyuan Liu

Coordinated synthesis and assembly of the cytoskeletal network contribute significantly to morphological changes during axon outgrowth. Previous studies demonstrated that heterogeneous ribonucleoprotein K (hnRNP K), an RNA binding protein, binds to the 3'-untranslated regions of all neurofilament triplet subunits, the most abundant components of the axonal cytoskeleton. These findings raised the hypothesis that hnRNP K post-transcriptionally mediates the coordinated expression of axonal cytoskeletal components. In my thesis, I test this hypothesis during both axonal development and regeneration.

Legacy Theses & Dissertations (2009 - 2024)
Ribonucleic acid (RNA) has been found to be a very versatile molecule, exhibiting countless functions and can act as a catalyst in biochemical reactions. These functions have typically been attributed to the unique structures that it forms. Novel non-coding RNAs capable of regulating gene expression are still being discovered, and the scope of the RNA world is still being uncovered. The structure function relationship of two different types of non-coding RNA has been investigated: riboswitches and sxRNAs. UV-monitored thermal denaturation experiments, Nuclear Magnetic Resonance spectroscopy, native gel electrophoresis and an in vivo luciferase assay were used to investigate the structural …
