Ribosome Shunting

**Definition:** Viral mechanisms of translational programming in which ribosomes reach the start codon bypassing or shunting over large segments of the 5′ UTR of VIRAL RNA. Ribosome shunting allows host translational machinery to engage polycistronic transcripts similar to RIBOSOMAL FRAMESHIFTING, and use of INTERNAL RIBOSOME ENTRY SITES.
