Characterization Of The Dimerization Domains On The Mannose-6-Phosphate/Insulin-Like Growth Factor Ii Receptor, Tyler Degener
Characterization Of The Dimerization Domains On The Mannose-6-Phosphate/Insulin-Like Growth Factor Ii Receptor, Tyler Degener
Theses/Capstones/Creative Projects
The mannose-6-phosphate/insulin-like growth factor II (M6P/IGF2) receptor is a transmembrane protein known to sequester growth factors from the extracellular matrix. This behavior suggests a mechanism of tumor suppression. Structurally, the receptor’s extracellular region is segmented into 15 homologous repeats, which are divided further into 5 triplet domains, labelled 1-3, 4-6, 7-9, 10-12, and 13-15. What is notable about the triplets is their propensity to form dimers with triplets on a second M6P/IGF2 receptor. In fact, previous studies indicate that this protein functions optimally when dimerized. Thus, the purpose of this experiment is to characterize these domain interactions. Using a urea …
Iron-Sulfur Cluster Assembly; In Vivo Analysis Of The Methanogenic Suf System, Evan Dunkle
Iron-Sulfur Cluster Assembly; In Vivo Analysis Of The Methanogenic Suf System, Evan Dunkle
LSU Master's Theses
Iron-sulfur (Fe-S) clusters are among the most ancient and prevalent of all biological cofactors. Their assembly into associated proteins is a tightly regulated process with many organisms employing multiple cluster assembly pathways. Much is known about Fe-S cluster assembly in aerobic organisms such as Escherichia coli (E. coli) but little is known in regards to cluster assembly in more ancient organisms such as methanogens. Methanogens are members of the domain of Archaea and are defined by their ability to generate methane as a byproduct of their main energy generating pathway. Methanogens also have significantly higher Fe-S cluster content …
Evaluating Methods Of Obtaining Male Pheromone From Hymenochirus Sp. Using Analytical Chemistry, Vincent Wing-Kun Leung
Evaluating Methods Of Obtaining Male Pheromone From Hymenochirus Sp. Using Analytical Chemistry, Vincent Wing-Kun Leung
University of the Pacific Theses and Dissertations
Male Hymenochirus sp. frogs are known to release pheromone that attracts females of the same species. Four methods for collecting secretions containing pheromone in Hymenochirus sp. were tested: norepinephrine injection, gonadotropin-releasing hormone injection, homogenization of gland tissue, and electrostimulation of the skin over the breeding gland area. The samples collected were analyzed using high-performance liquid chromatography (HPLC) and mass spectrometry. The HPLC chromatograph for the male norepinephrine sample contained a peak at 6.4 min that was not in the female norepinephrine sample HPLC chromatograph. The male norepinephrine sample mass spectrum had a peak of m/z 292.0 not in the female …
Structural Investigation Of Bcsc: Insight Into Periplasmic Transport During Cellulose Export, William Scott, Joel T. Weadge
Structural Investigation Of Bcsc: Insight Into Periplasmic Transport During Cellulose Export, William Scott, Joel T. Weadge
Theses and Dissertations (Comprehensive)
A biofilm can be defined by a community of microbes coexisting within a self-produced protective polymeric matrix. Exopolysaccharide (EPS) is a key component in biofilms and a contributor to their virulence and pathogenicity. The cellulose bacterial synthesis complex is one such EPS system that is found in many Enterobacteriaceae,including Escherichia coli and Salmonella spp., and is responsible for the production and secretion of the EPS cellulose. BcsC is the periplasmic protein responsible for the export of the exopolysaccharide cellulose and was the focus of this research. Sequence homology comparisons and structural predictions between BcsC, and the previously characterized alginate …

Mitogen activated protein kinases (MAPKs) are Ser/Thr kinases that relay the extracellular signal into intracellular responses and regulate several biological responses. They are classified into conventional MAPKs and atypical MAPKs. Extracellular signal regulated kinase 3 (ERK3) is an atypical MAPK that has a single phospho-acceptor site (Ser 189) in its activation motif instead of the canonical Thr-Xaa-Tyr (TXY) motif of conventional MAPK like ERK1/2. ERK3 comprises of a unique C terminal tail and a central C34 domain that further distinguishes it from ERK1/2. Moreover, compared to ERK1/2, much less is known about the upstream activators and the downstream targets of …

Understanding the inter-individual variability in physical fitness performance has been the focus of scientific research for decades especially in the United States military. Injury and physical inadequacy cost the U.S military millions of dollars every year. The project PHITE (Precision High Intensity Training through Epigenetics) was funded to investigate this personal complex trait by combing the genetic and epigenetic (non-shared environmental factors) contributions into a single model for physical training response. This project is set up as having 150 male and female recruits between the ages of 18-27 years old. Each participant is randomly put blind into either a high …

Non-melanoma skin cancer (NMSC) is a group of skin cancer that includes basal cell carcinoma of the skin (BCC), squamous cell carcinoma of the skin (SCC), actinic keratoses, a precursor to SCC, and other rare cutaneous carcinomas. p63, a member of the p53 gene family, is an important regulator for epithelial tissue growth and development. ∆Np63α, a main isoform of p63, is highly expressed in NMSC and plays essential roles in NMSCs development. Extracellular signal-regulated kinase 3 (ERK3) is an atypical member of the MAPK family. It possesses a single phosphorylation site (serine 189) in its activation loop, which makes …
