T2A
T2A is a self-cleaving 2A peptide (The average length is 18–22 amino acids) that could be applied in expression of more than one gene in cells. It is a good candidate to replace IRES because of its small size and high cleavage efficiency between genes upstream and downstream of the 2A peptide. [1]
In our project, we found that protein coding genes downstream were not expressed if they followed another protein coding gene directly. Taking advantage of function of T2A, we constructed a plasmid that T2A linked between two protein coding genes. For example, we constructed BBa_K1993006 (Luciferase-T2A-dTomato-T2A-hFTH) to ensure luciferase, dTomato and hFTH could be expressed.
