Electronic Theses and Dissertations
The protein tyrosine phosphatase (PTP) superfamily is a major segment of the signal transduction landscape, responsible for regulating the biomolecular phosphorylation status of the cell. Diverse PTP subclasses exist, some of which are understudied and whose cellular functions are not yet fully elucidated. YVH1, an atypical PTP of the dual-specificity phosphatase (DUSP) subclass, is a pleiotropic enzyme with no known substrate. Human YVH1 (hYVH1) protects cells from cellular stressors, including heat shock and oxidative stress, regulates the cell cycle, disassembles stress granules, and acts as 60S ribosome biogenesis factor. Additionally, heat shock protein 70 (Hsp70) has been found to be …

JC polyomavirus (JCPyV) is a human-specific pathogen that infects 50-80% of the population, and can cause a deadly, demyelinating disease, known as progressive multifocal leukoencephalopathy (PML). In most of the population, JCPyV persistently infects the kidneys but during immunosuppression, it can reactivate and spread to the central nervous system (CNS), causing PML. In the CNS, JCPyV targets two cell types, astrocytes, and oligodendrocytes. Due to the hallmark pathology of oligodendrocyte lysis observed in disease, oligodendrocytes were thought to be the main cell type involved during JCPyV infection. However, recent evidence suggests that astrocytes are targeted by the virus and act …

Electronic Theses and Dissertations
Zinc (Zn2+) is the second most abundant transition metal in the body and is important in various biological functions. Fluorescent sensors based on circularly permuted fluorescent proteins (cpFPs) have been previously made to detect labile, or unbound, Zn2+ within the cytoplasm of cells. These sensors have proven invaluable for studying Zn2+, however, these sensors are limited to their use in the cytoplasm and by the fact that only green cpFP have been utilized to create fluorescent Zn2+ sensors. In this thesis, we use a combination of peptide targeting sequences, site-directed mutagenesis, and rational design …

Fragile X Syndrome (FXS) is a neurodevelopmental disorder caused by the disruption of Fragile X Mental Retardation Protein (FMRP) function in neurons, affecting nearly 1 in 7,500 individuals. Although FXS typically occurs from a complete loss of FMRP expression due to a CGG trinucleotide expansion within the 5’UTR of the FMR1 gene, single nucleotide polymorphisms (SNPs) within the KH domains of FMRP have been shown to severely disrupt FMRP function. FMRP is an RNA-binding translation repressor that interacts with ~4% of the neuronal transcriptome. Many target mRNAs encode for proteins important for regulating synaptic processes and modulate synaptic plasticity. It …
