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.

Direct Recruitment Of Eif4gi And/Dap5 To The 5' Utr Of A Subset Of Human Mrna Drives Their Cap-Independent Translation, Solomon A. Haizel
Dissertations, Theses, and Capstone Projects
During unfavorable cellular conditions (e.g., tumor hypoxia, viral infection, nutrient deprivation, etc.), the canonical, cap-dependent translation initiation pathway in human cells is suppressed by sequestration of the cap-binding protein, eukaryotic initiation factor(eIF) 4E, by 4E-binding proteins. Circumvention of cap-dependent translation shutdown has been linked to tumor development and cancer progression. The stress-induced repression of cap-dependent translation has also been correlated with increased eIF4GI and its homolog, Death Associated Protein 5 (DAP5) expression levels, suggesting these factors have a role in cap-independent translation. Despite several evidence pointing towards a link upregulation of eIF4GI and /DAP5 levels during stress conditions, and the …
