Determining The Roles Of The Oligomerization And C-Terminal Domains In Mutant P53 Gain-Of-Function Activities, George K. Annor Sep 2022

Determining The Roles Of The Oligomerization And C-Terminal Domains In Mutant P53 Gain-Of-Function Activities, George K. Annor

Dissertations, Theses, and Capstone Projects

The tumor suppressor p53 (TP53) gene is often mutated in cancer, with missense mutations found in the central DNA binding domain, and less often in the oligomerization domain (OD) and C-terminal domain (CTD). The OD and CTD have been found to be critical for the tumor suppressor functionality of wild-type p53 (wtp53). Specific missense mutations in the DNA binding domain have been found to confer new gain-of-function (GOF) activities. Mutations that destabilize tetramer formation, or deletion of key lysine residues within the CTD, downregulate the ability of wtp53 to transactivate (increase the rate of transcription of) its target …


Eukaryotic Initiation Factor 4e (Eif4e) In Complex With Eif4e Binding Protein 1 (4e-Bp1) Binds With Higher Affinity To M7gpppn Cap Of A Subset Of Human Mrnas, Izza F. Nawaz Apr 2022

Eukaryotic Initiation Factor 4e (Eif4e) In Complex With Eif4e Binding Protein 1 (4e-Bp1) Binds With Higher Affinity To M7gpppn Cap Of A Subset Of Human Mrnas, Izza F. Nawaz

Theses and Dissertations

Fluorescence anisotropy binding assays were used to analyze the binding of eIF4E in complex with 4E-BP1 onto the 5’ m7G cap of a subset of mRNA that are known to carry cap-independent translation. These studies suggest that 4E-BP1 increases eIF4E binding affinity to 5’cap of both FGF-9 and HIF-1𝝰.


Paddling Along The Voltage Gated Sodium Channel Galaxy With Sea Anemone Toxins: Structural Studies Of The Interaction Between The Paddle Motif From Nav1.5div And Sea Anemone Toxin, Adel K. Hussein Feb 2022

Paddling Along The Voltage Gated Sodium Channel Galaxy With Sea Anemone Toxins: Structural Studies Of The Interaction Between The Paddle Motif From Nav1.5div And Sea Anemone Toxin, Adel K. Hussein

Dissertations, Theses, and Capstone Projects

Voltage gated sodium channels (VGSC) are membrane proteins that serve an important function in the central nervous system (CNS), peripheral nervous system (PNS), and cardiac muscles amongst others. The main function of VGSC is in the propagation of electrical signals by depolarizing excitable cells. Nine mammalian VGSC subtypes have been characterized, NaV1.1 – NaV1.9, that are expressed in a tissue specific manner, each with unique gating properties. Numerous diseases have been linked to defects in VGSC including epilepsy, mental retardation, long QT syndrome, and Brugada disease. Furthermore, these channels are one of the primary targets of …
