Wagner et al., Boston, United States. In J Biol Chem, 2013
The eIF4E translation initiation factors, eIF4E1, eIF4E2, and eIF4E3, are essential for translation initiation.
Investigating the consequences of eIF4E2 (4EHP) interaction with 4E-transporter on its cellular distribution in HeLa cells.
Standart et al., Cambridge, United Kingdom. In Plos One, 2012
We investigate here the interaction of human eIF4E2 (4EHP), a class II eIF4E protein, which binds the cap weakly, with eIF4E-transporter protein, 4E-T.
Quantitative evaluation of viability- and apoptosis-related genes in Ascaris suum eggs under different culture-temperature conditions.
Lee et al., Taejŏn, South Korea. In Korean J Parasitol, 2012
Here, unembryonated A. suum eggs were incubated at 20°C, 50°C, and 70°C in vitro, and the gene expression levels related to viability, such as eukaryotic translation initiation factor 4E (IF4E), phosphofructokinase 1 (PFK1), and thioredoxin 1 (TRX1), and to apoptosis, such as apoptosis-inducing factor 1 (AIF1) and cell death protein 6 (CDP6), were evaluated by real-time quantitative RT-PCR.

Sonenberg et al., Montréal, Canada. In Mol Cell Biol, 2012
GIGYF2 and the zinc finger protein 598 (ZNF598) are identified as components of the 4EHP complex.
An oxygen-regulated switch in the protein synthesis machinery.
Lee et al., Ottawa, Canada. In Nature, 2012
We show that hypoxia stimulates the formation of a complex that includes the oxygen-regulated hypoxia-inducible factor 2α (HIF-2α), the RNA-binding protein RBM4 and the cap-binding eIF4E2, an eIF4E homologue.
