2024年11月8日 · Eukaryotic initiation factor 4 A (eIF4A) plays critical roles during translation initiation of cellular mRNAs by forming the cap-binding eIF4F complex, recruiting...
The exon-junction complex helicase eIF4A3 controls cell fate via …
Eukaryotic initiation factor 4A-III (eIF4A3), a core helicase component of the exon junction complex, is essential for splicing, mRNA trafficking, and nonsense-mediated decay processes …
eIF4A3 Phosphorylation by CDKs Affects NMD during the Cell …
2019年2月19日 · Ryu et al. show that eIF4A3 (a core EJC component) is phosphorylated at the threonine 163 position by CDK1 and CDK2 in a cell cycle-dependent manner. This event …
The DEAD-box helicase eIF4A: Paradigm or the odd one out?
The overall topology of the human eIF4A-I/eIF4G/eIF4H complex has been dissected in a combination of NMR, mutational and binding studies. 53 Interactions were identified between …
Discovery and Characterization of a Eukaryotic Initiation ... - PubMed
2017年7月21日 · No small molecules for NMD inhibition via selective inhibition of eIF4A3 have been discovered. Here, we identified allosteric eIF4A3 inhibitors from a high-throughput …
Expression and Functional Roles of Eukaryotic Initiation Factor 4A ...
In this review, we explored the predicted structures of the three eIF4A isoforms (eIF4A1, eIF4A2, and eIF4A3), and discussed possible explanations for which function during different …
Expression and Functional Roles of Eukaryotic Initiation Factor 4A ...
