Design Notes
Two restriction sites (NdeI and SacI) have been added in both ends for digestion and ligation.
6X His tag has been added at the beginning for purification.
One restriction site, NheI, has been added between 6X His tag and the AC-P19 peptide for future modification.
A middle linker is added between AC-P19 peptides and cell-penetrating peptide
Polyarginine Cell-Penetrating Peptide: Peptides, especially intracellular functional peptides that can play a particular role inside a cell, have attracted attention as promising materials to control cell fate. However, hydrophilic materials like peptides are difficult for cells to internalize18. Octaarginine (R8) as a Polyarginine Cell-Penetrating Peptide (CPP) is reported to enhance peptide’s ability to cross the cell membrane and deliver cargo19. Hence, ‘RRRRRRRR’ is used as our signal peptide sequence for penetrating cell membrane and enter the cell.
