Thermodynamically Favorable Interactions between eIF4E Binding Domain of eIF4GI with Structured 5'-Untranslated Regions Drive Cap-Independent Translation of Selected mRNAs.
Phosphorylation of Eukaryotic Initiation Factor 4G1 (eIF4G1) at Ser1147 Is Specific for eIF4G1 Bound to eIF4E in Delayed Neuronal Death after Ischemia.
For unraveling mechanisms of RACK1:PKCbetaII-mediated translation stimulation we used sequentially truncated eIF4G1 in coimmunoprecipitation analyses to delineate a set of autoinhibitory elements in the N-terminal unstructured region (surrounding the eIF4E-binding motif) and the interdomain linker (within the eIF3-binding site) of eIF4G1.
We found that RACK1:PKCbetaII phosphorylates eukaryotic initiation factor 4G1 (eIF4G1) at S1093 and eIF3a at S1364. Our findings reveal a physiological role for ribosomal RACK1 in providing the molecular scaffold for PKCbetaII and its role in coordinating the translational response to PKC-Raf-ERK1/2 activation.
Epstein-Barr Virus protein EB2 first is recruited to the mRNA cap structure in the nucleus and then interacts with the proteins eIF4G and PABP to enhance the initiation step of translation.
