Undergraduate Research Posters 2013
Apolipoprotein A-I (apoA-I) is the main protein constituent of high density lipoprotein (HDL - the “good cholesterol”). Oxidatively damaged apoA-I has been isolated from circulating plasma and atherosclerosis plaque with the amino acid residue tryptophan 72 (W72) of apoA-I identified as a primary oxidation site. ApoA-I designed to include specific oxidized amino acids can be used to further investigate the role of site-specific oxidative damage in atherosclerosis. Genetic encoding of oxidized amino acids through orthogonal tRNA/aminoacyl-tRNA synthetase (aaRS) pairs offers a reliable method for producing site-specific oxidized proteins. Our project involves the generation of Saccharomyces tryptophan-RS mutants for recognition of …

Mining activity in Butte, Montana has taken place, or continues to take place, within the urban residence of Butte itself. This has led to urban areas with high concentrations of toxic metals such as arsenic, lead, copper, zinc, mercury and cadmium. Advances in protein study and gene sequencing has opened the possibility of finding molecular biomarkers whose presence, absence or morphological changes could indicate disease processes in populations exposed to environmental toxins. While in principle, biomarkers can be any chemicals or metabolites, as well as proteins and genes that are indicative of exposure to xenobiotics, this study seeks to identify …
Helix Turn Helix Domain, David J. Hall
Helix Turn Helix Domain, David J. Hall
Protein Domains
Helix turn helix domain #3V1A. The helix-turn helix is a DNA-binding domain. The two alpha helices are the reading or recognition helices, which bind in a groove in the DNA and recognize specific gene regulatory sequences in the DNA.
Ring Domain, David J. Hall
Ring Domain, David J. Hall
Protein Domains
Ring domain #1CHC. The RING finger is a specialized type of Zn finger consisting of 40–60 residues that binds two atoms of zinc, and is involved in mediating protein—protein interactions. Many zinc fingers bind nucleic acids. The presence of a RING finger domain is a characteristic of RING-class E3 ubiquitin protein ligases capable of transferring ubiquitin from an E2 enzyme to a substrate protein.
Sh2 Domain, David J. Hall
Sh2 Domain, David J. Hall
Protein Domains
SH2 domain #1BFJ. Src-homology 2 (SH2) domains are modules of ~100 amino acids that bind to specific phospho tyrosine (pY) containing peptide motifs. Conventional SH2 domains have a conserved pocket that recognizes pY, and a more variable pocket that binds 3-6 residues C-terminal to the pY and confers specificity.
Sh3 Domain, David J. Hall
Sh3 Domain, David J. Hall
Protein Domains
SH3 domain #1NEB. Src-homology 3 (SH3) domains bind to Pro-rich peptides that form a left-handed poly-Pro type II helix, with the minimal consensus Pro-X-X-Pro. Each Pro is usually preceeded by an aliphatic residue. Each in the aliphatic-Pro pair binds to a hydrophobic pocket on the SH3 domain.
Ig Domain, David J. Hall
Ig Domain, David J. Hall
Protein Domains
Ig domain #2CKN. This particular domain is named for the first protein in which it was found, the immunoglobulin. An immunoglobulin is a antibody. Antibodies are generated by our immune system to recognize the specific size, shape and charge of pathogens. This domain is also found on the extracellular portion of many receptors including the interleukin-1 family of receptors.
Beta Barrel, David J. Hall
Beta Barrel, David J. Hall
Protein Domains
Beta barrel (cyan fluorescent protein) #4AR7. This fluorescent protein is a variation of green fluorescent protein from a jellyfish and is the only domain that is a complete protein. The protein is routinely used to visualize a variety of biological processes. The beta barrel domain is a beta sheet wrapped around the fluorescent active site to provide structure.
Phi X 174, David J. Hall
Phi X 174, David J. Hall
Infectious Pathogens
Phi X 174 database number # 1CD3. Phi X 174 is a virus that infects bacteria and was the first DNA-based genome to be sequenced in 1977. This bacteriophage has a [+] circular single-stranded DNA genome. The assembly of the capsid has been successfully done in vitro and is the focus of many studies on self-assembly, drug delivery and nanotechnology.

Human Papilloma Virus 16, David J. Hall
Infectious Pathogens
Human Papilloma virus 16, database# 1DZL Infection by most papillomaviruses is either asymptomatic or causes small benign tumors, known as papillomas or warts (e.g. human papillomavirus HPV6 or HPV11). Papillomas caused by some types, however, such as human papillomaviruses 16 and 18, carry a risk of becoming cancerous. Human papilloma virus is a non-enveloped, double stranded, circular DNA virus.
Dengue Virus, David J. Hall
Dengue Virus, David J. Hall
Infectious Pathogens
Dengue virus, database # 1THD Dengue fever, is an infectious tropical disease caused by the dengue virus and transmitted by mosquito. Symptoms include fever, headache, muscle and joint pains, and a characteristic skin rash that is similar to measles. In a small proportion of cases the disease develops into the life-threatening dengue hemorrhagic fever. Dengue is a positive strand RNA virus that is part of the flavivirus family. Dengue is an enveloped virus meaning it has a nucleocapsid protecting the RNA and the nucleocapsid is surrounded by lipids (hence the name enveloped).
Hepatitis B, David J. Hall
Hepatitis B, David J. Hall
Infectious Pathogens
Hepatitis B, database # 2g33. Hepatitis B is an infectious inflammatory illness of the liver caused by the hepatitis B virus (HBV). Hepatitis B virus (HBV) is a member of the Hepadnavirus family.The virus particle, (virion) consists of an outer lipid envelope and an icosahedral nucleocapsid core composed of protein. These virions are 42 nM in diameter. The nucleocapsid encloses the viral DNA and a DNA polymerase that has reverse transcriptase activity.

A cancer cell’s most threatening property is its ability to metastasize or detach from the primary tumor and migrate to other locations in the body. Previous studies have shown that overexpression of the enzyme cyclooxygenase-2 (COX-2) can increase the metastatic potential of several cell types. COX-2 is the rate-limiting enzyme in the prostanoid biosynthesis pathway, converting arachidonic acid to prostaglandin H2, an important signaling molecule in the body. Glycosylation of COX-2 at the amino acid site Asn580 occurs about 50% of the time, and this results in two forms of the enzyme with molecular weights 72 and 74kDa. The purpose …
