Structure of an antigen-binding fragment bound to stem-loop DNA and crystallization of recombinant haemophilus influenzae e(P4) acid phosphatase
(University of Missouri--Columbia, 2006)
DNA-1 and 11F8 are anti-ss DNA antibodies derived from autoimmune lupus-prone mice. They are very similar to each other in terms of CDR sequence and preference for binding T-rich ss DNA. G1-17 is an oligonucleotide identified ...
The use of FD-filamentous bacteriophage for the in vivo imaging of cancer
(University of Missouri--Columbia, 2006)
Improved diagnosis of cancer through targeted imaging of neoplasms is needed for early detection and treatment of cancer. We propose that the physical characteristics of filamentous bacteriophage (phage) are well suited ...
The role of P2Y₂ nucleotide receptors in vascular inflammation
(University of Missouri--Columbia, 2007)
Extracellular nucleotides act on P2 receptors to regulate vascular tone. Large amounts of extracellular nucleotides are released at the sites of tissue injury and may play an important role in the vascular inflammation. ...
Structural and functional studies of proline catabolic enzymes
(University of Missouri--Columbia, 2007)
Catabolism is the oxidation of organic nutrients into simple end molecules to extract energy. For proline, the catabolic pathway involves two enzymes, Lproline dehydrogenase (PRODH, EC 1.5.99.8) and L-[delta]¹-pyrroline- ...
Characterization of SF-hERR[beta] repression of human estrogen receptor alpha and estrogen receptor-beta transcriptional activities
(University of Missouri--Columbia, 2009)
Discovery of new ways to modulate estrogen actions through estrogen receptor is always exciting because of the importance of estrogen and ERs in many human diseases. In this dissertation, we report our discovery of the ...
Discovery of epitopes governing MMP-12 specificity for fibrillar substrates : BINDSIght, a method for determining specific sites of substrate surface interactions
(University of Missouri--Columbia, 2008)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] What determines MMP-12 elastase activity? We have found that the fibrillar substrate specificity of MMP-12 involves surfaces ranging beyond the ...
Structure and conformational signaling in the escherichia coli aspartate receptor tar
(University of Missouri--Columbia, 2014)
Shape modeling framework for brain and facial image analysis
(University of Missouri--Columbia, 2011)
The field of medical image analysis has greatly influenced the practice of neuroscience. Many studies aim to find new disease related anatomical characteristics based on the analysis of Magnetic Resonance images (MRI). ...
Examination of metabolic and regulatory networks of desulfovibrio species
(University of Missouri--Columbia, 2004)
The sulfate-reducing bacteria are a morphologically diverse group of organisms characterized by the ability to couple the enzymatic reduction of sulfate to energy production and growth. This metabolic activity has profound ...
Characterization and functional significance of Msc2p & Zrg17p, which form a zinc transport complex in the endoplasmic reticulum of Saccharomyces cerevisiae
(University of Missouri--Columbia, 2004)
We demonstrate a novel interaction between two members of the cation diffusion facilitator (CDF) family in Saccharomyces cerevisiae: Msc2p and a newly recognized CDF family member, Zrg17p. Both Msc2p and Zrg17p have been ...
Glomerular deposition of homotrimeric type I collagen in the COL1A2 deficient mouse
(University of Missouri--Columbia, 2006)
Type I collagen is the most abundant structural protein in the body. Type I collagen generally exists as a heterotrimeric protein; however, a homotrimeric isotype of type I collagen has been identified. Our lab currently ...
Understanding Arabidopsis ion homeostasis in the post-genomic era : assigning function to two proteins involved in iron metabolism
(University of Missouri--Columbia, 2006)
Two projects studying different aspects of iron deficiency in the model plant Arabidopsis thaliana are detailed here. The first project describes the isolation and characterization of the Arabidopsis frd4-1 and frd4-2 ...
Kinase-interacting FHA domain of kinase associated protein phosphatase : phosphopeptide interactions and NMR-detected dynamics
(University of Missouri--Columbia, 2007)
FHA domains are phosphoThr recognition modules found in diverse signaling proteins. Kinase-associated protein phosphatase (KAPP) from Arabidopsis employs its FHA domain in its negative regulation of some receptor-like ...
Regulation of Nrf2 by a keap1-dependent E3 ubiquitin ligase
(University of Missouri--Columbia, 2007)
Oxidative damage to biological macromolecules has been implicated in diverse pathophysiological processes, including cancer, neurodegeneration, aging and cardiovascular disease. The Nrf2 transcription factor regulates ...
Characterization and functional analysis of the P2Y₂R gene promoter
(University of Missouri--Columbia, 2006)
Extracellular nucleotides can bind to the P2Y₂R and modulate proliferation and migration of smooth muscle cells, which is known to be involved in intimal hyperplasia that accompanies atherosclerosis and post-angioplasty ...
Molecular and cell biological studies of mammalian zinc transporters
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Zinc is an essential trace element in all organisms. The importance of the hZIP4 human zinc transporter is highlighted by its causative role in a ...
Secretory phospholipase A2-IIA in Alzheimer's disease and inflammatory responses in astrocytes
