Eukaryotic translation is a complex biochemical process requiring several initiation factors. The first step in the initiation of mRNA translation involves binding of the small ribosomal subunit to mRNA.{25365} The central component in the recruitment of the pre-initiation complex during translation is the eukaryotic initiation factor 4F (eIF4F) complex, composed of eIF4A, eIF4E, and eIF4G1/eIF4G3.{25357} The 5’-terminal end of eukaryotic mRNA has a common cap structure that is important for stabilizing mRNA and ribosome binding.{25366} The eIF4E component binds specifically to the mRNA cap structure to initiate protein synthesis by recognizing methyl-7-guanosine.{25357,25363} eIFA is a DEAD-box helicase, responsible for unwinding the mRNA, while eIF4G acts as a scaffold protein with binding sites for the poly(A)-binding protein and eIF3. eIF4G also possesses central and C-terminal eIF4A binding sites and a C-terminal binding site for the protein kinase Mnk1 (mitogen-activated protein kinase-interacting kinase).{25364} Mnk1 phosphorylates eIF4E at Ser209, which is believed to be essential for eIF4E’s oncogenic potential.{25361,25359,25360} Further, overexpression of eIF4e is seen in many human malignancies, including breast, colon, head and neck carcinomas, and others.{25358,25362}
