Investigating the roles and functions of plasma membrane E3 ligases and MKP1 in plant immunity
(University of Missouri--Columbia, 2021)
When a plant encounters a pathogen, a complex set of responses occurs on both sides of the interaction. In a process known as pattern-triggered immunity (PTI), the plant uses plasma membrane (PM)-localized proteins, or ...
A novel role for the ATP7A copper transporter in cancer
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Copper is a trace metal with a ready capacity to gain or donate electrons. This property is harnessed by numerous enzymes to perform vital functions ...
Roles of clathrin-coated vesicle networks in plant immunity and development
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] For a plant cell, the plasma membrane (PM) is not only the interface with its environment but also a signaling platform. Proteins localized to the PM ...
Single cell-type metabolomics of Medicago truncatula border cells and their roles in host-microbe interactions
(University of Missouri--Columbia, 2022)
Border cells are a specialized cell type surrounding the root apical meristematic region of many plant species, with the exception of the Brassicaceae family that possess characteristically different border-like cells. ...
Methods of partitioning, biogenesis, and selecting for natural and engineered CoA-RNA
(University of Missouri--Columbia, 2023)
More than a decade ago, RNAs with NAD+, CoA, and acylated CoA caps were identified. Since then, studies have described NAD+'s protective, cap-like function in bacteria and its role in promoting mRNA degradation in eukaryotic ...
Structural and kinetic studies of proline metabolic enzyme inhibitors and inactivators
(University of Missouri--Columbia, 2021)
Structural and kinetic studies of the proline metabolic enzymes proline dehydrogenase (PRODH), [delta]1-pyrroline-5-carboxylate reductase (PYCR), and aldehyde dehydrogenase 4A1 (ALDH4A1) are presented in this thesis. ...
Structural studies of domain of unknown function 507 (DUF507)
(University of Missouri--Columbia, 2023)
The crystal structure of the domain of unknown function family 507 protein from Aquifex aeolicus is reported (AaDUF507, UniProt O67633, 183 residues). The structure was determined in two space groups (C2221 and P3221) at ...
Characterization of the effects of 3,3'-diindolylmethane (DIM) in the TRAMP mouse prostate cancer model and DIM's interaction with estrogen receptor signaling
(University of Missouri--Columbia, 2018)
3,3'- diindolylmethane (DIM) is an acid -derived compound formed during the digestion of indole-3-carbinol (I3C), which is one of the main compounds in cruciferous vegetables, such as broccoli, cabbage and kale. Studies ...
Aptamers that bind filovirus GP : a new frontier for detection and neutralization of Ebola and Marburg virus
(University of Missouri--Columbia, 2020)
Aptamers are single chained, nucleic acid-based affinity probes that bind to their targets with strong affinity and specificity. They are made through an in vitro combinatorial selection method, wherein large libraries of ...
Selective modulation of estrogen receptors : 27-hydroxycholesterol is a negative allosteric modulator of er-beta activity and estradiol binding
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The estrogen receptors alpha (ER[alpha]) and beta (ER[beta]) are important regulators of development and growth in many major organ systems. In the ...
Molecular mechanisms of enzyme dysfunction in human phosphoglucomutase-1 deficiency
(University of Missouri--Columbia, 2019)
Human phosphoglucomutase-1 (PGM1) belongs to the [alpha]-D-phosphohexomutase superfamily, an ancient lineage of enzymes critical for carbohydrate metabolism. PGM1 catalyzes the interconversion of glucose-1-phosphate and ...
The minimal primary structures of RNA aptamers selected to bind HIV-1 reverse transcriptase
(University of Missouri--Columbia, 2010)
Human Immunodeficiency Virus (HIV) reverse transcriptase (RT) is the most common molecular target of current HIV treatments. Oligonucleotide aptamers bind and inhibit the RNA- and DNA-dependent polymerization activities ...
Amyloid beta induces cPLA2 activation by an NADPH oxidase-dependent mechanism in neurons
(University of Missouri--Columbia, 2008)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Alzheimer's disease (AD) is a neurodegenerative disorder affecting more than 20 million people worldwide. An increase in production of amyloid beta ...
