Eukaryotic translation initiation: there are (at least) two sides to every story
A B Sachs et al. Nat Struct Biol. 2000 May.
Abstract
The eukaryotic cap and poly(A) tail binding proteins, eIF4E and Pab1p, play important roles in the initiation of protein synthesis. The recent structures of the complex of eIF4E bound to the methylated guanosine (cap) found at the 5'end of messenger RNA (mRNA), the complex of eIF4E bound to peptide fragments of two related translation factors (eIF4G and 4E-BP1), and the complex of the N-terminal fragment of Pab1p bound to polyadenylate RNA have revealed that eIF4E and Pab1p contain at least two distinct functional surfaces. One surface is used for binding mRNA, and the other for binding proteins involved in translation initiation.
