Eukaryotic initiation factor 4A-I (also known as eIF4A1 or DDX2A) is a 46 kDa cytosolic protein that, in humans, is encoded by the EIF4A1 gene, which is located on chromosome 17. It is the most prevalent member of the eIF4A family of ATP-dependant RNA helicases, and plays a critical role in the initiation of cap-dependent eukaryotic protein translation as a component of the eIF4F translation initiation complex. eIF4A1 unwinds the secondary structure of RNA within the 5'-UTR of mRNA, a critical step necessary for the recruitment of the 43S preinitiation complex, and thus the translation of protein in eukaryotes. eIF4A1 is an ATP-dependent RNA helicase, however the exact nature of its dependence on ATP for its function is still debated. Although after ATP binding, the subsequent hydrolysis induces conformational changes in eIF4A1, other DEAD-box RNA helicases have been shown to possess helicase activity in the presence of nonhydrolyzable analogues of ATP, suggesting that binding, and not hydrolysis, is the more important element in regulating activity. eIF4A1 is a component of the eIF4F translation initiation complex, along with eIF4E, the 5'-terminal cap binding protein, and eIF4G, the scaffold protein that holds eIF4A and eIF4E together. The eIF4F complex is often accompanied by the accessory proteins eIF4B and eIF4H, either of which can differentially enhance the activity of eIF4A1. After mRNA is transcribed from DNA and translocated to the cytoplasm, and the cytosolic PABP is bound to the Poly(A)-tail of the nascent mRNA, its 5'-cap will bind to eIF4E and PABP will bind to eIF4G. eIF4A1 will then unwind the RNA secondary structure from 5' to 3' as the 43S PIC is recruited to the eIF4F complex. The 43S PIC will scan the unwound mRNA from 5' to 3' as well, until it reaches the AUG start codon, whereupon the 60S ribosomal subunit will be recruited to begin the process of elongation.
