Translation of many cellular and viral mRNAs is directed by internal ribosomal entry sites (IRESs). Several proteins that enhance IRES activity through interactions with IRES elements have been discovered. However, the molecular basis for the IRES-activating function of the IRES-binding proteins remains unknown. Here, we report that NS1-associated protein 1 (NSAP1), which augments several cellu...

We have used lactoperoxidase-catalyzed iodination to study the topographical distribution of proteins in free and membrane-bound polysomes and in isolated ribosomal subunits. Free polysomes or rough microsomes were iodinated with 125I and then dissociated into 40 S and 60 S subunits by the use of puromycin/KCl. The separated subunits were iodinated with 13’1 and their protein composition analyz...
