<p>Eukaryotic translation initiation factor A (eIF-1A) (formerly known as eiF-4C) is a protein that seems to be required for maximal rate of protein biosynthesis. It enhances ribosome dissociation into subunits and stabilises the binding of the initiator Met-tRNA to 40S ribosomal subunits [<cite idref="PUB00002919"/>]. The archaea possess an eIF-1A homolog.</p>
