The Tobamovirus internal ribosome entry site (IRES) is an element that allows cap and end-independent translation of mRNA in the host cell.[1] The IRES achieves this by mediating the internal initiation of translation by recruiting a ribosomal 43S pre-initiation complex directly to the initiation codon and eliminates the requirement for the eukaryotic initiation factor, eIF4F.[2]
