Prokaryotic-like cis elements in the cap-independent internal initiation of translation on picornavirus RNA.

Initiation of translation on picornavirus RNAs is accomplished through internal binding of ribosomes to a complex cis-acting element. Here we show that efficient function of this element involves two appropriately spaced smaller elements: UUUCC and an AUG. This conclusion emerged from analysis of the genome structures of spontaneous revertants of mutant… CONTINUE READING
