Supplementary Figure 8: Sequence of a drug-controllable dSpCas9-based transcriptional activator, VPR-dSpCas9(StaPLTI).
From: StaPLs: versatile genetically encoded modules for engineering drug-inducible proteins

The StaPLTI module is inserted after residue 1246 of dSpCas9. Grey, artificial linkers. Blue, HA epitope tag. Purple, StaPL module, with the portion of the protease recognition substrate N-terminal to the cleavage site underlined.
