Fret Biosensors: Engineering Fluorescent Proteins As Biological Tools For Studying Parkinson’S Disease, Nathan J. Leroy, Jacob R. Norley, Saranya Radhakrishnan, Mathew Tantama
The Summer Undergraduate Research Fellowship (SURF) Symposium
Parkinson’s Disease (PD) is a common neurodegenerative disease with over 200,000 new cases each year. In general, the cause of the disease is unknown, but oxidative stress inside of neurons has been associated with the disease’s pathology for some time. Currently, techniques to study the onset of PD inside of neurons are limited. This makes treatments and causes difficult to discover. One solution to this has been fluorescent protein biosensors. In short, these proteins can be engineered to glow when a certain state is achieved inside a cell. The present research discusses the engineering of a genetically-encoded fluorescent protein (FP) …

The Summer Undergraduate Research Fellowship (SURF) Symposium
Purinergic signaling is a type of extracellular communication that occurs between cells, mediated by adenosine triphosphate (ATP), adenosine diphosphate (ADP), and adenosine. In Parkinson’s Disease, purinergic signaling is disrupted, which contributes to neurodegeneration. In order to monitor this change in cell-to-cell signaling, there is a need for the development of a fluorescent protein (FP) biosensor to study the changes in the concentration of the signaling molecule ATP and its decomposition bioproduct ADP. This summer a genetically encoded ADP sensor that measures changes in ADP concentration was developed. This sensor utilizes Forster Resonance Energy Transfer (FRET) which is a sensing technique …

Fret-Based Investigations Of The Structure-Function Relationships In The Nmda Receptor, Drew M. Dolino
Dissertations & Theses (Open Access)
The N-methyl-D-aspartate (NMDA) receptor is one member of a class of proteins known as the ionotropic glutamate receptors. Ionotropic glutamate receptors mediate the majority of excitatory neurotransmission in the central nervous system, with the NMDA receptor standing out among these receptors for its requirement of a co-agonist, its magnesium-block-based coincidence detection, its slow kinetics, its calcium permeability, its allosteric modulation, and its especially important functional roles in synaptic plasticity, excitotoxicity, and more. In recent years, a wealth of structural information has come about describing endpoint structures to high resolution, but such structures are unable to fully resolve the movements …
Frnk Regulatory Complex Formation With Fak Is Regulated By Erk Mediated Serine 217 Phosphorylation, Taylor J. Zak

Focal adhesion kinase related non-kinase (FRNK) is an endogenous inhibitor of focal adhesion kinase (FAK) that has traditionally been used to inhibit FAK signaling in a variety of experiments and is also an important endogenous regulator of FAK signaling. More recently, FRNK has been shown to be of increasing importance in some pathologic conditions. Despite the increasing importance of FRNK, the molecular mechanism by which it functions remains unclear. In addition, FRNK contains several phosphorylation sites with unknown importance and function. Here I hypothesize that FRNK can inhibit FAK by binding directly to FAK within focal adhesions. Furthermore, I propose …
Illuminate The Pathway Of Membrane Protein Association And Degradation, Zhaoshuai Wang
Illuminate The Pathway Of Membrane Protein Association And Degradation, Zhaoshuai Wang
Theses and Dissertations--Chemistry
Escherichia coli transporter protein AcrB and its homologues are the inner membrane components of the Resistance-Nodulation-Division (RND) family efflux pumps in Gram-negative bacteria. It is well accepted that soluble proteins are only marginally stable, but such insight is missing for membrane proteins. The lack of stability data, including thermodynamic stability and oligomer association affinity is a result of intrinsic difficulties in working with membrane proteins. In addition, the degradation of soluble proteins in E. coli has been extensively studied whereas the degradation process of membrane proteins remains unclear. A focus of my thesis is the validation and development of methods …
