Distinct Regulation of Internal Ribosome Entry Site-mediated Translation following Cellular Stress Is Mediated by Apoptotic Fragments of eIF4G Translation Initiation Factor Family Members eIF4GI and p97/DAP5/NAT1

Abstract excerpt

Many cellular stresses lead to the inhibition of protein synthesis. Despite this, some cellular mRNAs are selectively translated under these conditions. It was suggested that the presence of internal ribosome entry site (IRES) sequences in the 5'-untranslated regions allow these mRNAs to be actively translated despite the overall cessation of protein synthesis. Here we tested the hypothesis that the IRES elements...
