Controlling Gene Expression through RNA Regulons: The Role of the Eukaryotic Translation Initiation Factor eIF4E

Abstract excerpt

The eukaryotic translation initiation factor eIF4E is a potent oncogene. In fact, its overexpression in human cancer often correlates with poor prognosis. Traditionally, eIF4E plays a role in translation initiation where it binds the 5' m7G cap found on mRNAs. More recent studies indicate that a significant fraction of eIF4E (up to 68%) resides in the nucleus where it regulates the nuclear export of specific...
