The Disordered Regulation Of Calcineurin: How Calmodulin-Induced Regulatory Domain Structural Changes Lead To The Activation Of Calcineurin, Victoria B. Dunlap
The Disordered Regulation Of Calcineurin: How Calmodulin-Induced Regulatory Domain Structural Changes Lead To The Activation Of Calcineurin, Victoria B. Dunlap
Theses and Dissertations--Molecular and Cellular Biochemistry
Calcineurin (CaN) is a highly regulated Ser/Thr protein phosphatase that plays critical roles in learning and memory, cardiac development and function, and immune system activation. Alterations in CaN regulation contribute to multiple disease states such as Down syndrome, cardiac hypertrophy, Alzheimer’s disease, and autoimmune disease. In addition, CaN is the target of the immunosuppressant drugs FK506 and cyclosporin A. Despite its importance, CaN regulation is not well understood on a molecular level. Full CaN activation requires binding of calcium-loaded calmodulin (CaM), however little is known about how CaM binding releases CaN’s autoinhibitory domain from the active site. Previous work has …

Critical Events In Human Metapneumovirus Infection: From Entry To Egress, Brent A. Hackett
Theses and Dissertations--Molecular and Cellular Biochemistry
Human metapneumovirus (HMPV) is a respiratory pathogen in Paramyxovirus family that demonstrates extremely high morbidity in the population, with most individuals having been infected by the age of five. Despite the prevalence of this negative-sense RNA virus in the population for decades, it was only identified in 2001. As such, there is currently no specific treatment for HMPV and the potentially severe consequences of infection for elderly and immunocompromised individuals and particularly infants make development of antivirals targeting HMPV of high significance. HMPV constitutes a quarter of all respiratory hospitalizations among infants, placing it second only to RSV, in addition …

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 …
