Characterization Of The Function And Regulation Of The Hmpv Phosphoprotein, Rachel Thompson
Characterization Of The Function And Regulation Of The Hmpv Phosphoprotein, Rachel Thompson
Theses and Dissertations--Molecular and Cellular Biochemistry
Human metapneumovirus (HMPV) is a non-segmented, negative strand RNA virus (NNSV) that frequently causes respiratory tract infections in infants, the elderly, and the immunocompromised. Despite the initial identification of HMPV in 2001, there are currently no FDA approved antivirals or vaccines available. Therefore, understanding the mechanism of HMPV replication is critical for the identification of novel therapeutic targets. A key feature in the replication cycle of HMPV and other NNSVs is the formation of membrane-less, liquid-like replication and transcription centers in the cytosol termed inclusion bodies (IBs). Recent work on NNSV IBs suggests they display characteristics of biomolecular condensates formed …
The Development And Characterization Of Nanobodies Specific To Protein Tyrosine Phosphatase 4a3 (Ptp4a3/Prl-3) To Dissect And Target Its Role In Cancer., Caroline Smith
Theses and Dissertations--Molecular and Cellular Biochemistry
Protein Tyrosine Phosphatase 4A3 (PTP4A3 or PRL-3) is an oncogenic dual-specificity phosphatase that drives tumor metastasis, promotes cancer cell survival, and is correlated with poor patient prognosis in a variety of solid tumors and leukemias. The mechanisms that drive PRL-3’s oncogenic functions are not well understood, in part due to a lack of research tools available to study this protein. The development of such tools has proven difficult, as the PRL family is ~80% homologous and the PRL catalytic binding pocket is shallow and hydrophobic. Currently available small molecules do not exhibit binding specificity for PRL-3 over PRL family members, …
Functional Characterization Of Scaffold Protein Shoc2, Hyein Jang
Functional Characterization Of Scaffold Protein Shoc2, Hyein Jang
Theses and Dissertations--Molecular and Cellular Biochemistry
Signaling scaffolds are critical for the correct spatial organization of enzymes within the ERK1/2 signaling pathway and proper transmission of intracellular information. However, mechanisms that control molecular dynamics within scaffolding complexes, as well as biological activities regulated by the specific assemblies, remain unclear.
The scaffold protein Shoc2 is critical for transmission of the ERK1/2 pathway signals. Shoc2 accelerates ERK1/2 signaling by integrating Ras and RAF-1 enzymes into a multi-protein complex. Germ-line mutations in shoc2 cause Noonan-like RASopathy, a disorder with a wide spectrum of developmental deficiencies. However, the physiological role of Shoc2, the nature of ERK1/2 signals transduced through this …
Investigating Therapeutic Options For Lafora Disease Using Structural Biology And Translational Methods, Amanda R. Sherwood
Investigating Therapeutic Options For Lafora Disease Using Structural Biology And Translational Methods, Amanda R. Sherwood
Theses and Dissertations--Molecular and Cellular Biochemistry
Lafora disease (LD) is a rare yet invariably fatal form of epilepsy characterized by progressive degeneration of the central nervous and motor systems and accumulation of insoluble glucans within cells. LD results from mutation of either the phosphatase laforin, an enzyme that dephosphorylates cellular glycogen, or the E3 ubiquitin ligase malin, the binding partner of laforin. Currently, there are no therapeutic options for LD, or reported methods by which the specific activity of glucan phosphatases such as laforin can be easily measured. To facilitate our translational studies, we developed an assay with which the glucan phosphatase activity of laforin as …
