Abstract

Translation initiation begins with the assembly of the pre-initiation complex followed by the formation of the initiation complex. The process of initiation then continues until the first peptide bond is formed; it is at this point that translation begins. The formation of the pre-initiation/initiation complex is often the rate-limiting step during the process of translation, as it is influenced by a number of translational regulatory mechanisms. As a result, the process of initiation can play a significant role in gene expression.
