The translation of many proteins involved in transcription, cell cycle progression, apoptosis and cell survival is mediated by internal ribosome entry sites (IRESs) present within the 5'-untranslated regions (5'-UTRs) of their messenger RNA molecules (mRNAs). Several recent reports now demonstrate that the proteins controlling IRES-dependent translation initiation are regulated by their subcellular localization.
