Multiple applications of genome editing by CRISPR-Cas9 necessitate stringent
regulation and Cas9 variants have accordingly been generated whose activity
responds to small ligands, temperature or light. However, these approaches are
often impracticable, for example in clinical therapeutic genome editing in situ
or gene drives in which environmentally-compatible control is paramount. With
this in mind, we have developed heritable Cas9-mediated mammalian genome editing
that is acutely controlled by the cheap lysine derivative, Lys(Boc) (BOC).
Genetic code expansion permitted non-physiological BOC incorporation such that
Cas9 (Cas9(BOC)) was expressed in a full-length, active form in cultured somatic
cells only after BOC exposure. Stringently BOC-dependent, heritable editing of
transgenic and native genomic loci occurred when Cas9(BOC) was expressed at the
onset of mouse embryonic development from cRNA or Cas9(BOC) transgenic females.
The tightly controlled Cas9 editing system reported here promises to have broad
applications and is a first step towards purposed, spatiotemporal gene drive
regulation over large geographical ranges.
