Translational control of protein synthesis in the pancreas is important in regulating growth and the synthesis of digestive enzymes. Regulation of translation is primarily directed at the steps in initiation and involves reversible phosphorylation of initiation factors (eIFs) and ribosomal proteins. Major sites include the assembly of the eIF4F mRNA cap binding complex, the activity of guanine nucleotide exchange factor eIF2B, and the activity of ribosomal S6 kinase. All of these involve phosphorylation by different regulatory pathways. Stimulation of protein synthesis in acinar cells is primarily mediated by the phosphatidylinositol 3-kinase-mTOR pathway and involves both release of eIF4E (the limiting component of eIF4F) from its binding protein and phosphorylation of ribosomal S6 protein by S6K. eIF4E is itself phosphorylated by a distinct pathway. Inhibition of acinar protein synthesis can be mediated by inhibition of eIF2B following phosphorylation of eIF2alpha.
