Lay summary:

Gene expression is the way in which the cell uses DNA as instructions for making proteins. The process is extensively regulated and carefully managed. In a healthy cell, changes in gene expression allow the cell to adapt to changes in conditions. Myc is a cellular protein that is involved in regulation of the expression of numerous other genes and is itself highly regulated. If myc is altered, either in its levels or in its structure then this can cause cancer. Synthesis of the myc protein is unusual in that the protein synthesis machinery is recruited differently and assembles at a unique site on the intermediate RNA. This paper identifies other proteins that are involved in myc regulation and includes experiments that study the way these proteins bind to the myc RNA and how they affect myc protein synthesis. Myc is a good model for the study of this alternative mechanism of protein synthesis. In addition, research into genes that are involved in cancer is vital to improving our understanding of the disease
