Two AcrIIC3-LOV2 hybrids potently blocked NmeCas9 activity in the dark while permitting robust genome editing upon blue light irradiation.
Two AcrIIC3-LOV2 hybrids from our collection potently blocked NmeCas9 activity in the dark, while permitting robust genome editing at various endogenous loci upon blue light irradiation.
The work demonstrates optogenetic regulation of a type II-C CRISPR effector and suggests a route for designing optogenetic anti-CRISPR proteins.
Together, our work demonstrates optogenetic regulation of a type II-C CRISPR effector and might suggest a new route for the design of optogenetic Acrs.
This paper reports the first optogenetic tool to control NmeCas9 activity in mammalian cells via an engineered light-dependent anti-CRISPR protein.
Here, we report the first optogenetic tool to control NmeCas9 activity in mammalian cells via an engineered, light-dependent anti-CRISPR (Acr) protein.
Structural analysis indicated that the LOV2 domain in the hybrids is located close to the Cas9 binding surface.
Structural analysis revealed that, within these hybrids, the LOV2 domain is located in striking proximity to the Cas9 binding surface.

The Cas-ON system was adapted to Neisseria meningitidis Cas9 using its cognate inhibitors AcrIIC1 and AcrIIC3.
Finally, to showcase its modularity, we adapted our Cas-ON system to the smaller and more target-specific Neisseria meningitidis (Nme) Cas9 orthologue and its cognate inhibitors AcrIIC1 and AcrIIC3.
