Abstract

A 24 000-dalton protein [yeast eukaryotic initiation factor 4E (eIF-4E)] was purified from yeast Saccharomyces cerevisiae postribosomal supernatant by m7GDP-agarose affinity chromatography. The protein behaves very similarly to mammalian protein synthesis initiation factor eIF-4E with respect to (i) binding to and elution from m7GDP-agarose columns and (ii) cross-linking to oxidized reovirus mRNA cap structures. Yeast eIF-4E is required for translation as shown by the strong and specific inhibition of cell-free translation in a yeast extract by a monoclonal antibody directed against yeast eIF-4E.
