Specificity, Allostery, and Multivalency in Binding to the Hub Protein LC8

Creator:: Estelle, Aidan B.
Abstract:: Interactions between proteins are essential to life, driving and regulating a majority of processes within all living cells. Study of protein-protein interactions reveals that some proteins act as hubs within networks of interactions, binding to many partner proteins. These hubs therefore are of particular importance to understanding protein function, interwoven...

Towards a Better Understanding of How the Dietary Supplement Xanthohumol Can Improve Health

Creator:: Logan, Isabelle E.
Abstract:: Xanthohumol, a prenylated flavonoid found in hops and beer, possesses a long-standing reputation to improve health. Xanthohumol’s cytotoxicity to a wide variety of cancer cell lines is well-established. Herein we provide further insight into the cytotoxicity of not only xanthohumol, but also its non-estrogenic derivatives, to a number of colonic...

Viral Targeting of Host Hubs: Interactions between the Rabies Virus and LC8

Creator:: Jespersen, Nathan E.
Abstract:: As obligate intracellular parasites, viruses rely on host machinery for their own reproduction. Viruses are therefore required to interact with a wide variety of host proteins, despite limitations in viral genome size. The most parsimonious method of success is to hijack central and essential proteins, known as hub proteins. LC8...

Model systems for structural investigations into peroxiredoxin catalysis, conformation change, and inactivation

Creator:: Perkins, Arden
Abstract:: Peroxiredoxin (Prx) enzymes catalyze the reduction of hydrogen peroxide, peroxynitrous acid, and organic peroxides, and are extremely efficient peroxidases, with k[subscript cat]/K[subscript M] on the order of 10⁷ - 10⁸ M⁻¹ s⁻¹. Besides their role in oxidative stress defense, evidence has accumulated that some eukaryotes, including humans, use Prxs as...

Transcriptional regulation of the human cathelicidin antimicrobial peptide gene

Creator:: Guo, Chunxiao
Abstract:: Human cathelicidin antimicrobial peptide (CAMP/LL-37) is a cationic antimicrobial peptide that is widely expressed by myeloid and epithelial cells at the human-environment interface. It possesses broad spectrum antimicrobial capacity against bacteria, fungi and viruses. In addition to its direct antimicrobial activity, CAMP/LL-37 also attracts and recruits monocytes, neutrophils and other...

Peroxiredoxins in Parasites

Creator:: Gretes, Michael C., Poole, Leslie B., and Karplus, P. Andrew
Abstract:: Significance: Parasite survival and virulence relies on effective defenses against reactive oxygen and nitrogen species produced by the host immune system. Peroxiredoxins (Prxs) are ubiquitous enzymes now thought to be central to such defenses and, as such, have potential value as drug targets and vaccine antigens. Recent Advances: Plasmodial and...

Calpain 2 proteolysis regulates glioblastoma cell invasion

Creator:: Lal, Sangeet Kumar
Abstract:: Glioblastoma is the most malignant primary brain tumor with the average patients surviving only one year after diagnosis, even with aggressive therapy. The formation of numerous micro-tumors dispersed into the brain due to rapid invasion of tumor cells, presents the primary challenge to the surgical removal of tumors and limits...

Characterization of the mechanism and function of C₂H₂ zinc finger protein CTIP2 in the developmental processes

Creator:: Golonzhka, Olga
Abstract:: CTIP2 is a C2H2 zinc finger transcription factor that plays important yet poorly understood roles in mouse development. CTIP2 is known to be highly expressed in the central nervous system, skin and T lymphocytes during embryogenesis. CTIP2-null mice die perinatally of unknown causes and exhibit defects in multiple organ systems...

Analyses of noncanonical DNA structures

Creator:: Khuu, Patricia A.
Abstract:: The structural polymorphic nature of DNA has been long been recognized since the model of the right-handed B-DNA duplex proposed by James Watson and Francis Crick was accepted. Its malleability is thought to be critical in protein recognition and manipulation. In particular, it can form Holliday junctions, four-way DNA structural...

Structure and function of chromatin : studies at the nucleosome and nuclear matrix levels

Creator:: Shih, Ah Shing
Abstract:: Several levels of eukaryotic chromatin structure have been observed: the nucleosome, the 10 nm and 30 nm fibers and loop domains, apparently attached to the nuclear matrix. In this research, the structure and function of chromatin at two of these levels was investigated, with studies on both nucleosome positioning and...
