Tests Of The Extension And Deadbolt Models Of Integrin Activation, Jieqing Zhu, Brian Boylan, Bing Hao Luo, Peter J. Newman, Timothy A. Springer

Faculty Publications

Despite extensive evidence that integrin conformational changes between bent and extended conformations regulate affinity for ligands, an alternative hypothesis has been proposed in which a "deadbolt" can regulate affinity for ligand in the absence of extension. Here, we tested both the deadbolt and the extension models. According to the deadbolt model, a hairpin loop in the β3 tail domain could act as a deadbolt to restrain the displacement of the β3 I domain β6-α7 loop and maintain integrin in the low affinity state. We found that mutating or deleting the β3 tail domain loop has no effect on ligand binding …

The N-Terminal Extensions Of Deinococcus Radiodurans Dps-1 Mediate Dna Major Groove Interactions As Well As Assembly Of The Dodecamer, Gargi Bhattacharyya, Anne Grove

Faculty Publications

Dps (DNA protection during starvation) proteins play an important role in the protection of prokaryotic macromolecules from damage by reactive oxygen species. Previous studies have suggested that the lysine-rich N-terminal tail of Dps proteins participates in DNA binding. In comparison with other Dps proteins, Dps-1 from Deinococcus radiodurans has an extended N terminus comprising 55 amino acids preceding the first helix of the 4-helix bundle monomer. In the crystal structure of Dps-1, the first ∼30 N-terminal residues are invisible, and the remaining 25 residues form a loop that harbors a novel metal-binding site. We show here that deletion of the …

Search For A Knox Gene In Kalanchöe Pinnatum, Ryan Michael Gleason

Undergraduate Honors Thesis Collection

Knox genes have been found in nearly all eukaryotic organisms. These genes code for a protein that is able to bind DNA. By binding to DNA, it is capable of controlling the expression of other genes. The coded sequence of these genes has been determined in many different organisms, but has yet to be searched for in the air plant, Kalanchoe pinnatum. I did research over the past year in an attempt to find the coded sequence of Kalanchoe's Knox gene. I grew Kalanchoe in Butler's greenhouse to accumulate enough plant material to begin work. I then extracted the RNA …

Solar Energy Research And Development In California, Brett T. Close

Pomona Senior Theses

The energy crisis of 2001, high prices for gas and electricity and worries of climate change have caused a growing awareness about energy issues in California. The problems are clear. This paper looks at the next step of finding and implementing solutions. In this case the contribution that solar photovoltaic and solar thermal generation could make toward solving the problem. This paper looks at technological change, the current state of solar energy research, current government policies on solar energy, and finally makes policy recommendations to meet the stated problem.

The Notch Regulator Maml1 Interacts With P53 And Functions As A Coactivator., Yongtong Zhao, Rebecca B. Katzman, Laurie M. Delmolino, Ishfaq Bhat, Ying Zhang, Channabasavaiah B. Gurumurthy, Aleksandra Germaniuk-Kurowska, Honey V. Reddi, Aharon Solomon, Mu-Sheng Zeng, Aisha Kung, Hui Ma, Qingshen Gao, Goberdhan Dimri, Adina Stanculescu, Lucio Miele, Lizi Wu, James D. Griffin, David E. Wazer, Hamid Band, Vimla Band

Journal Articles: Biochemistry & Molecular Biology

Members of the evolutionarily conserved Mastermind (MAM) protein family, including the three related mammalian Mastermind-like (MAML) proteins MAML1-3, function as crucial coactivators of Notch-mediated transcriptional activation. Given the recent evidence of cross-talk between the p53 and Notch signal transduction pathways, we have investigated whether MAML1 may also be a transcriptional coactivator of p53. Indeed, we show here that MAML1 is able to interact with p53. We show that MAML1-p53 interaction involves the N-terminal region of MAML1 and the DNA-binding domain of p53, and we use a chromatin immunoprecipitation assay to show that MAML1 is part of the activator complex that …

Selenoprotein H Is A Nucleolar Thioredoxin-Like Protein With A Unique Expression Pattern, Sergey V. Novoselov, Gregory V. Kryukov, Xue-Ming Xu, Bradley A. Carlson, Dolph L. Hatfield, Vadim N. Gladyshev

Vadim Gladyshev Publications

The human selenoproteome consists of 25 known selenoproteins, but functions of many of these proteins are not known. Selenoprotein H (SelH) is a recently discovered 14-kDa mammalian protein with no sequence homology to functionally characterized proteins. By sensitive sequence and structure analyses, we identified SelH as a thioredoxin fold-like protein in which a conserved CXXU motif (cysteine separated by two other residues from selenocysteine) corresponds to the CXXC motif in thioredoxins. These data suggest a redox function of SelH. Indeed, a recombinant SelH shows significant glutathione peroxidase activity. In addition, SelH has a conserved RKRK motif …

Cattail Distribution End Abundance In North Dakota, Scott T. Ralston, G. M. Linz, W. J. Bleier, H. J. Homan

United States Department of Agriculture Wildlife Services: Staff Publications

Wetlands in the Prairie Pothole Region (PPR) of North Dalcota provide important habitats for a plethora of invertebrate and vertebrate animals. Since 1991, glyphosate-based (N-phosphonomethyl-glycine) herbicides have been used to manage dense cattail (Typha spp. L.) stands on 29,522 ha of wetlands in the PPR to disperse blackbird roosts. Limited information exists on the abundance and distribution of this important habitat. We took aerial photographs and used geospatial analysis tools to identify wetland basins and cattail coverage on randomly selected sample sites within the PPR. We found that average wetland density and size were 13 wetlands/ km² and …

A Study Of Selected Student Attitudes Toward Factors That Influence Academic Achievement, Marquis L. Bennett

Theses and Dissertations

The purpose of this study was to investigate the attitudes of selected African-American male college students and the impact of financing, role-modeling, high school preparation, college/community acceptance, and family support on academic achievement at Rowan University. The study sought to determine if any of these factors had a significant relationship with academic achievement.

Academic achievement was measured by a self-reported GPA of 2.76 or higher, which was higher than Rowan University's minimum requirement (2.5) for graduation, and honors achievements (awards, certificates, honor societies). Responses were measured using a Likert scale of 1-Strongly Agree to 5-Strongly Disagree.

Respondents reported that financial …

Biomass And Coal Fly Ash In Concrete: Strength, Durability, Microstructure, Quantitative Kinetics Of Pozzolanic Reaction And Alkali Silica Reaction Investigations., Shuangzhen Wang

Theses and Dissertations

Biomass represents an important sustainable energy resource, with biomass-coal cofiring representing among the most effective and cost efficient CO2 reduction strategies. Fly ash generated during coal combustion represents a technically advantageous, inexpensive, and environmentally beneficial admixture in concrete production, partially replacing cement. However, strict interpretation of American Society of Testing and Materials (ASTM) and American Concrete Institute (ACI) standards prohibits use of fly ashes from any source other than coal in concrete production; therefore, fly ash from biomass coal cofiring is excluded from use in concrete. This dissertation discusses biomass impacts on concrete properties through experiments conducted on several combinations …

Increased Abundance Of Arbuscular Mycorrhizal Fungi In Soil Coincides With The Reproductive Stages Of Maize, M. Susana Grigera, Rhae A. Drijber, Brian J. Wienhold

Department of Agronomy and Horticulture: Faculty Publications

Arbuscular mycorrhizal (AM) fungi are recognized for their positive effects on plant growth, playing an important role in plant P nutrition. We used C16:1cis11 and C18:1cis11 fatty acid methyl ester (FAME) biomarkers to monitor the dynamics of AM fungi during the reproductive stages of maize (Zea mays L.) grown at high yield in Nebraska, USA. Two fields with four different levels of P availability were sampled throughout the reproductive stages. Chambers, made of PVC enclosed mesh fabric to allow passage of roots and hyphae(+R) or hyphae alone (-R) and amended with either KH₂PO …
