Protein Trafficking In The Endoplasmic Reticulum Mediated By A Tpr-Containing Adapter Protein, Nathan P. Canniff
Protein Trafficking In The Endoplasmic Reticulum Mediated By A Tpr-Containing Adapter Protein, Nathan P. Canniff
Doctoral Dissertations
The endoplasmic reticulum (ER) is a large, multifunctional organelle that acts as the entrance into the secretory pathway, which accounts for the folding and maturation of approximately one third of the human proteome. It is the largest organelle in most cell types and is comprised of a single lumen and a contiguous membrane. The ER is responsible for a multitude of roles including protein translocation, folding, maturation, quality control, and glycosylation to name a few. These processes are buoyed by a large collection of chaperones and cochaperones, the largest subfamily of which is characterized by the presence of tetratricopeptide repeat …

Combining Simulation And The Mspa Nanopore To Study P53 Dynamics And Interactions, Samantha A. Schultz
Masters Theses
p53 is a transcription factor and an important tumor suppressor protein that becomes activated due to DNA damage. Because of its role as a tumor suppressor, mutations in the gene that encodes it are found in over 50% of human cancers. The N-terminal transactivation domain (NTAD) of p53 is intrinsically disordered and modulates the function and interactions of p53 in the cell. Its disordered structure allows it to be controlled closely by post-translation modifications that regulate p53’s ability to bind DNA and interact with regulatory binding partners. p53 is an attractive target for developing cancer therapeutics, but its intrinsically disordered …

During viral infection, virus and host clash for control of the cell in a conflict that ultimately drives the evolution of both sides and has lasting consequences in the form of pathogenesis. At the heart of this struggle is a contest for control of cellular gene expression, a struggle epitomized by an evolutionary tug-of-war for supremacy over RNA fate. During lytic replication, Kaposi’s sarcoma-associated herpesvirus (KSHV) triggers a massive RNA decay event known as viral “Host Shutoff” which decimates greater than 70% of the host transcriptome, simultaneously suppressing the cellular anti-viral response and freeing host resources for viral replication. However, …
Modulation Of Plant Immunity During The Establishment Of The Nitrogen-Fixing Symbiosis, Miriam Hernandez-Romero
Modulation Of Plant Immunity During The Establishment Of The Nitrogen-Fixing Symbiosis, Miriam Hernandez-Romero
Doctoral Dissertations
Nitrogen is essential for plant tissue growth but is often a limited resource in soils. Many legumes overcome this limitation by entering a symbiotic association with soil microbes, called rhizobia, which provide nitrogen to the plant while rhizobia receive fixed carbon. To successfully form a symbiosis, the host and symbiont exchange a series of molecular signals. One major obstacle during this interaction is the host's innate immune system, which becomes active upon rhizobial detection. It is therefore the main focus of this thesis to identify the mechanisms that modulate host immunity. In the subsequent chapters, we focus on a rhizobial …
