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 ...
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 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. ...
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 role of Candida albicans homologous recombination factors Rad54 and Rdh54 in DNA damage sensitivity
(2011-09-27)
Abstract
Background
The fungal pathogen Candida albicans is frequently seen in immune suppressed patients, and resistance to one of the most widely used antifungals, fluconazole (FLC), can evolve rapidly. In recent years ...
A unified phylogeny-based nomenclature for histone variants
(2012-05-31)
AbstractHistone variants are non-allelic protein isoforms that play key roles in diversifying chromatin structure. The known number of such variants has greatly increased in recent years, but the lack of naming conventions ...
CPP-ZFN: A potential DNA-targeting anti-malarial drug
(2010-09-16)
Abstract
Background
Multidrug-resistant Plasmodium is of major concern today. Effective vaccines or successful applications of RNAi-based strategies for the treatment of malaria are currently unavailable. An unexplored ...
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, ...
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 ...
The Role of Host Translation Initiation Factors eIF4H and eIF4A and the Exon Junction Complex in the Control of mRNA turnover and Translation by the Virion Host Shut off Protein of Herpes Simplex Virus
(2013)
During lytic infections, the HSV Vhs endonuclease (UL41) degrades many viral and cellular mRNAs. This endonuclease activity is dependent upon the ability of Vhs to bind the host translation initiation factors eIF4AI/II and ...
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 ...
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 ...
Potential Mechanisms for Inhibition of Breast Cancer by Novel Azaresveratrol Analogs: Implications of Estrogen Receptor, Estrogen Metabolism and Cell Death Pathways
(2015-06-19)
Prolonged exposure to estrogens has been implicated in the development of breast cancers. Steroidal estrogens have been implicated in the initiation and progression of cancer. Estrogens bind to their cognate estrogen ...
Analyzing the effects of Cis-elements and trans-factors on the stability of the Gal1 mRNP
(2014)
The highly dynamic and nonrandom spatial organization of the eukaryotic nucleus plays an important role in the regulation of gene expression. For example, in S. cerevisiae, several conditionally expressed genes relocate ...
Determining the differential roles of the dock family of GEFs in drosophila development
(2015-05-19)
The evolutionarily conserved Dock proteins function as unconventional guanine
nucleotide exchange factors (GEFs). Upon binding to ELMO (Engulfment and cell
motility) proteins, Dock-ELMO complexes activate the Rho family ...
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 ...
Independent Functions Of Clueless In Differential Integrin Secretion And Mitochondrial Quality Control In Drosophila Muscle
