Compositions and methods are provided for the inhibition of the function of RNA guided endonucleases, including the identification and use of such inhibitors. Methods of identifying inhibitor compounds of RNA guided nucleases, assays for detecting nuclease activity and compounds for use therein are also provided.

Inhibitors of RNA-guided nuclease activity and uses thereof

The present inventions generally relate to site-specific delivery of nucleic acid modifiers and includes novel DNA-binding proteins and effectors that can be rapidly programmed to make site-specific DNA modifications. The present inventions also provide a synthetic all-in-one genome editor (SAGE) systems comprising designer DNA sequence readers and a set of small molecules that induce double-strand breaks, enhance cellular permeability, inhibit NHEJ and activate HDR, as well as methods of using and delivering such systems.

Nucleic acid modifiers

Compositions and methods for conditionally regulating activities of CRISPR-Cas systems. In some embodiments, the methods comprise providing an inactive guide RNA comprising a regulatory domain bound by a lock nucleic acid different from the guide RNA; and displacing the lock nuclei acid from the regulatory domain by a trigger nucleic acid, thereby activating the guide RNA, wherein the activated guide RNA forms a complex with a Cas enzyme.

Compositions and methods for regulating proteins and nucleic acids activities

The embodiments disclosed herein utilize fluorescence polarization based preliminary screen to identify a putative set of Cas inhibitors from an initial set of candidate inhibitors. The primary screening assay is followed by secondary screening assay to validate the putative set of inhibitors selected by the preliminary screen. In some embodiments, the present disclosure includes compositions and methods are provided for the inhibition of the function of RNA guided endonucleases, including the identification and use of such inhibitors.
