Abstract
The invention provides for systems, methods, and compositions for targeting nucleic acids. In particular, the invention provides non-naturally occurring or engineered RNA-targeting systems comprising a novel RNA-targeting CRISPR effector protein and at least one targeting nucleic acid component like a guide RNA.
Claims
exact text as granted — not AI-modifiedWhat is claimed:
1 . An in vitro method for targeting a target RNA in a sample comprising target RNA and non-target RNA, comprising contacting said target RNA with a CRISPR-Cas protein and a guide RNA, wherein the effector protein forms a complex with the guide RNA, and wherein the guide RNA directs the complex to bind the target RNA.
2 . The method of claim 1 , wherein the CRISPR-Cas protein is a type VI effector protein.
3 . The method of claim 1 , wherein the CRISPR-Cas protein comprises at least one HEPN domain.
4 . The method of claim 1 , wherein the CRISPR-Cas protein comprises two HEPN domains.
5 . The method of claim 1 , wherein the CRISPR-Cas protein is a C2c2 protein.
6 . The method of claim 5 , wherein the C2c2 protein is from a bacteria belonging to a genus selected from the group consisting of: Corynebacter, Sutterella, Legionella, Treponema, Filifactor, Eubacterium, Streptococcus, Lactobacillus, Mycoplasma, Bacteroides, Flaviivola, Flavobacterium, Sphaerochaeta, Azospirillum, Gluconacetobacter, Neisseria, Roseburia, Parvibaculum, Staphylococcus, Nitratifactor, Mycoplasma, Camplyobacter, Leptotrichia, Rhodobacter, Lachnospiraceae, Carnobacterium , and Paludibacter.
7 . The method of claim 5 , wherein the C2c2 protein is an orthologue comprising 80% sequence identity to an orthologue selected from the group consisting of Leptotrichia shahii DSM 19757 C2c2 : Rhodobacter capsulatus SB 1003 (RcS); Rhodobacter capsulatus R121 (RcR); Rhodobacter capsulatus DE442 (RcD); Lachnospiraceae bacterium MA2020 (Lb(X)); Lachnospiraceae bacterium NK4A179 (Lb(X); [ Clostridium ] aminophilum DSM_10710 (CaC); Lachnospiraceae bacterium NK4A144 (Lb(X); Leptotrichia wadei F0279 (Lew); Leptotrichia wadei F0279 (Lew); Carnobacterium gallinarum DSM 4847 (Cg); Carnobacterium gallinarum DSM 4847 (Cg); Paludibacter propionicigenes WB4 (Pp); Listeria seeligeri serovar 1/2b (Ls); Listeria weihenstephanensis FSL R9-0317 (Liw); and Listeria bacterium FSL M6-0635 (Lib).
8 . The method of claim 5 , wherein the C2c2 protein is an orthologue selected from the group consisting of Leptotrichia shahii DSM 19757 C2c2 : Rhodobacter capsulatus SB 1003 (RcS); Rhodobacter capsulatus R121 (RcR); Rhodobacter capsulatus DE442 (RcD); Lachnospiraceae bacterium MA2020 (Lb(X)); Lachnospiraceae bacterium NK4A179 (Lb(X); [ Clostridium ] aminophilum DSM_10710 (CaC); Lachnospiraceae bacterium NK4A144 (Lb(X); Leptotrichia wadei F0279 (Lew); Leptotrichia wadei F0279 (Lew); Carnobacterium gallinarum DSM 4847 (Cg); Carnobacterium gallinarum DSM 4847 (Cg); Paludibacter propionicigenes WB4 (Pp); Listeria seeligeri serovar 1/2b (Ls); Listeria weihenstephanensis FSL R9-0317 (Liw); and Listeria bacterium FSL M6-0635 (Lib).
9 . The method of claim 1 , wherein the CRISPR-Cas protein cleaves the target RNA and non-target RNA as a result of collateral effects of said CRISPR-Cas protein in said sample.
10 . The method of claim 9 , wherein said non-target RNA is labelled, preferably fluorescently labelled.
11 . The method of claim 10 , wherein the method further comprises detecting the cleavage of the labelled non-target RNA.
12 . The method of claim 11 , wherein the method further comprises comparing the detection of the cleavage of the labelled non-target RNA in the absence of the target RNA.
13 . The method of claim 5 , wherein the C2c2 effector protein is LshC2c2.
14 . The method of claim 5 , wherein the guide RNA does not comprise a tracr sequence.
15 . The method of claim 1 , wherein the target RNA is a disease associated RNA.
