Involvement of a specific ubiquitin ligase in the assembly of the dynein motor in the filamentous fungus Neurospora crassa
(University of Missouri--Kansas City, 2012-08-27)
Eukaryotic cells utilize multiple molecular motor proteins to accomplish
intracellular transport. The two microtubule based motors, kinesin and cytoplasmic
dynein, work in concert to move cargoes outward and inward, ...
Regulation of Antimicrobial Peptide Genes in the Tobacco Hornworm Manduca sexta
(2015-05-26)
The innate immune system, also known as natural or non-specific immune system, is conserved from insects to humans. The insect innate immune system is composed of humoral and cellular components. Insect humoral responses ...
3-Hydroxy-3-methylglutaryl-coenzyme A lyase: investigation of cysteines mediating intersubunit disulfide formation and regulation by thiol/disulfide exchange and discovery of an extramitochondrial homolog
(University of Missouri -- Kansas City, 2012-01-18)
3-Hydroxy-3-methylglutaryl-Coenzyme A lyase catalyzes the cleavage of 3-hydroxy-
3-methylglutaryl-Coenzyme A into acetoacetate and acetyl-Coenzyme A, a key reaction
in ketogenesis and leucine catabolism. Previous work ...
The herpes simplex virus virion host shutoff protein is targeted to mRNA cleavage sites through interactions with components of the host translational apparatus
(University of Missouri--Kansas City, 2011-01-20)
The virion host shutoff protein (Vhs) is a herpes simplex virus (HSV) protein involved in early shutoff of the host cell. It is a component of the infecting virion, located in the tegument region, that works by rapidly ...
A proteomic approach for studying LTR retrotransposon host factors in saccharomyces cerevisae
(University of Missouri--Kansas City, 2012-01-20)
The Ty retrotransposons of S. cerevisiae are mobile elements that resemble retroviruses, both in their genetic structures and replication cycles. Ty retrotransposition begins in the nucleus with the transcription of Ty ...
The expression and regulation on antimicrobial peptide genes in insects: studies in the tobacco hornworm manduca sexta
(University of Missouri--Kansas City, 2011-05-10)
Insects have evolved an efficient innate immune system to combat microbes. Most of our knowledge of insect immunity comes from studies with dipteran and lepidopteran insects, such as the fruit fly Drosophila melanogaster, ...
Structural and functional studies of type three secretion virulence factors from gram-negative pathogenic bacteria
(University of Missouri-Kansas City, 2011-12-21)
Many pathogenic Gram-negative bacteria utilize type III secretion systems (TTSS) to alter the normal functions of target host epithelial cells. Of the 1.1 million deaths that are caused by Shigella each year, nearly a third ...
Mutational and functional analyses of the dynein heavy chain indicate the existence of an apical-sistal transport cycle in cells
(University of Missouri--Kansas City, 2012-03-02)
The organization, survival, and function of eukaryotic cells depend on intracellular
transport governed by the microtubule based molecular motors cytoplasmic dynein and
kinesin. Dynein carries out the inward transport ...
The role of drosophila protein kinase doubletime in circadian period determination, morning and evening oscillators and tauopathy
(University of Missouri--Kansas City, 2012-10-01)
In this dissertation, I used the GAL4-UAS binary expression method to overexpress mutant and wild type forms of the circadian protein kinase DBT in order to address several basic questions about DBT's biological functions. ...
Modulation of neuronal ryanodine receptor-mediated calcium signaling by calsenilin
(2013)
Calsenilin is calcium (Ca2+) ion Ca2+ binding protein found in the nucleus, plasma membrane, and endoplasmic reticulum of neuronal cells. Calsenilin was first found to interact with two proteins involved in early-onset ...
Disconnecting a Role for DNA Repair in the Pathogenicity of the Human pathogen Cryptococcus neoformans
(2014)
C. neoformans is an opportunistic fungal pathogen causing fatal meningitis and lung infections. Worldwide every year around 625,000 deaths occur due to Cryptococcosis. A basic understanding of Cryptococcus virulence ...
The function of Drosophila Integrin-Dim7-Elmo-Mbc→Rac signaling pathway in the muscle attachment formation and maintenance
(2013)
The Engulfment and Cell Motility (Elmo)-(Myoblast city) Mbc→Rac signaling pathway is evolutionarily conserved from C. elegans to vertebrates and is essential for many developmental processes, including phagocytosis and ...
Independent Functions Of Clueless In Differential Integrin Secretion And Mitochondrial Quality Control In Drosophila Muscle
(2015)
Drosophila Clueless (Clu) and its conserved orthologs are known for their role in the prevention of mitochondrial clustering. Here, we uncover its independent roles in the delivery of integrin subunits and the regulation ...
Regulation of Gene Expression by Non-coding RNAs in Arabidopsis and Brachypodium
(2014)
Expansion of high-throughput sequencing technology has increased our understanding
in the importance of pervasive transcription and the resulting indispensable molecules, noncoding
RNAs (ncRNAs). A significant effort has ...
Mating Type Specific Roles During The Sexual Cycle Of Phycomyces Blakesleeanus
(2014)
Phycomyces blakesleeanus is a filamentous fungus that belongs in the order Mucorales. It can propagate through both sexual and asexual reproduction. The asexual structures of Phycomyces called sporangiophores have served ...
