P2A linker

Part Description

In order to mediate the "cleavage" of two proteins, 2A peptide sequences were discovered in Picornaviruses. Effective multiple protein expression from a single open reading frame (ORF) is achieved using 2A peptide-linked multicistronic vectors. Use alternative 2A peptide sequences when linking more than two genes to reduce the likelihood of homologous recombination. All eukaryotic systems studied to date, including mammalian cells, yeast, and plants, have effectively utilised the 2A peptide system.
