Abstract:
The cap-binding complex eIF-4F plays a major role in the control of translation initiation, and overexpression of its limiting subunit, eIF-4E, leads to the deregulation of cellular growth. The recent cloning of eIF-4E binding proteins (4E-BPs) has uncovered a previously unsuspected pathway for the regulation of eIF-4E activity, through sequestration of eIF-4E as a complex with 4E-BPs.
