WebEukaryotic translation initiation factor 5 (eIF5) forms a complex with eIF2 by interacting with the β subunit of eIF2. This interaction is essential for eIF5-promoted hydrolysis of GTP … WebMay 20, 2010 · Here we define new regulatory functions of eIF5 in the recycling of eIF2 from its inactive eIF2.GDP state between successive rounds of translation initiation. First we show that eIF5 stabilizes the binding of GDP to eIF2 and is therefore a bi-functional protein that acts as a GDP dissociation inhibitor (GDI).

WebMay 13, 2024 · The Sui – mutants at the eIF5-NTD did not show any of these defects, possibly due to the weak effect of these mutations on eIF5 function [24]. It is also likely that the eIF5-NTD does not directly participate in maintaining the integrity and scanning function of 48S complex and the G31R substitution may have only exacerbated the regulatory ... WebOct 30, 2014 · Both eIF2 and eIF5 are equally abundant, whereas eIF2B is roughly ten-fold less abundant. 13 The eIF5 carboxy terminal domain (CTD) is critical for its interaction with eIF2 and for its GDI function 6,14 and is a close structural mimic of the eIF2B GEF domain, that resides at the CTD of the largest eIF2B subunit (eIF2Bϵ). 15-17 Both eIF5 and ... sanwah construction singaporeWebJan 1, 2024 · Additionally, to understand the function of eIF5 in vivo in yeast cells, a conditional mutant yeast strain in which a functional but a rapidly degradable form of eIF5 fusion protein was synthesized from the glucose repressible GAL promoter was constructed.

"WebOct 27, 2005 · Mutations in eIF5-CTD also cause the Gcn – phenotypes (general control nonderepressible). In this phenotype, the restriction of the mutant eIF5-CTD function at a higher temperature (36°C) increases the frequency of scanning past uORF1, thereby impairing GCN4 translation derepression (11, 12). This underlines the role of eIF5-CTD in ... " - Eif5 function
