  "summary": "2A peptides are short (~18 to 22 amino acid) sequences utilized by a subset of RNA viruses to process their polyproteins in an unusual co-translational event known as StopGo or ribosome skipping. This process involves ribosome pausing at a conserved C-terminal D(V/I)ExNPGP motif, followed by peptidyl-tRNA hydrolysis of the nascent peptide-tRNAGly, and continued translation from the downstream…",
