Translation initiation, in both eukaryotes and bacteria, requires essential elements such as mRNA, ribosome , initiator tRNA, and a set of initiation factors. For each domain of life, canonical mechanisms and signals are observed to initiate protein synthesis. However, other initiation mechanism can be used, especially in viral mRNAs. Some viruses hijack cellular machinery to translate some of their mRNAs through a noncanonical initiation pathway using internal ribosome entry site (IRES), a highly structured RNAs which can directly recruit the ribosome with a restricted set of initiation factors, and in some cases even without cap and initiator tRNA. In this chapter, we describe the use of biosensors relying on electro-switchable nanolevers using the switchSENSE® technology, to investigate kinetics of the intergenic (IGR) IRES of the cricket paralysis virus (CrPV) binding to 80S yeast ribosome . This study provides a proof of concept for the application of this method on large complexes.
