Inhibition of eIF4E-dependent in vitro translation by 4E-binding peptides. 1 pmol eIF4E (green) or 1 pmol eIF4E/p20 (red) was added to in vitro translation reactions containing 5 ng capped GRE1-Luc mRNA. Additionally, 1 pmol of the following purified GST-fusion proteins were added: GST-Eap1106–273, GST-eIF4G441–492, GST-eIF4G160–492 and GST-eIF4G160–492 LL457,458/AA. 1 pmol GST alone had no stimulatory effect on translation. Data presented are the mean luminescence activity in relative light units (RLU ± s.e.m.; n = 3).
