ABSTRACT:
A detailed three-dimensional structure for the least abundant of the general translation initiation factors in eukaryotes, eIF4E, complexed with a ligand is disclosed. The novel N-terminal truncated eIF4Es which were constructed so as to omit a significant portion of the flexible N-terminal tail of the eIF4E are also part of the present invention. In addition, the crystals of the protein-ligand complexes containing the N-terminal truncated eIF4Es are also included. Furthermore, methods of identifying antagonists of the eIF4E protein which can be used to regulate protein synthesis in cells are also disclosed.
