porcine teschovirus-1 P2A Peptide Linker

P2A is a porcine teschovirus-1 derived self-cleavage 2A peptide. Compared to other 2A self-cleaving peptides, P2A has been shown to have relatively higher efficiency.

P2A linker works by ribosome skipping mechanism, that is, while translation is taking place, the ribosome skips an amino acid at the P2A linker site, thereby effectively separating the upstream protein from the downstream protein.

Due to these abilities, 2A Linkers can be effectively used as a small size replacement for IRES (Internal Ribosomal Entry Sites) while designing DNA sequences for recombinant protein (non-fused) in both prokaryotic and eukaryotic systems. Hence, this is a great tool for synthetic biology.


Usage and Biology

We planned to use this linker in BBa_K3889100, BBa_K3889101, BBa_K3889102, BBa_K3889110, BBa_K3889112, BBa_K3889120 and BBa_K3889122 in order to coexpress fluorescent proteins to report protein production.
