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-modified
What 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.
