RESUMO
We have isolated genomic and cDNA clones encoding protein synthesis initiation factor eIF-4E (mRNA cap-binding protein) of the yeast Saccharomyces cerevisiae. Their identity was established by expression of a cDNA in Escherichia coli. This cDNA encodes a protein indistinguishable from purified eIF-4E in terms of molecular weight, binding to and elution from m7GDP-agarose affinity columns, and proteolytic peptide pattern. The eIF-4E gene was isolated by hybridization of cDNA to clones of a yeast genomic library. The gene lacks introns, is present in one copy per haploid genome, and encodes a protein of 213 amino acid residues. Gene disruption experiments showed that the gene is essential for growth.
