Translation
... After the initiation complex assembles, it translocates along the mRNA in a process called scanning, until the initiation codon is reached. Scanning is facilitated by eukaryotic initiation factor eIF4A, which functions as an ATP-dependent helicase to unwind mRNA secondary structure while releasing ...
