Figure 5From: Recent advances in in vivo applications of intein-mediated protein splicingSchematic representation of conditional protein splicing (CPS). The brown color of the boxes indicates an inactive intein, whereas a blue intein is active. A. Conditional protein splicing triggered by protein trans-splicing. B. Conditional protein splicing triggered by protein cis-splicing. C. Conditional protein splicing triggered by change in redox state.Back to article page
