The microbial CRISPR systems enable adaptive defense against mobile elements, and also provide formidable tools for genome engineering. The Cas9 proteins are Type II CRISPR-associated, RNA-guided DNA endonucleases that identify double-stranded DNA targets by sequence complementarity and protospacer adjacent motif (PAM) recognition. Here we report that the Type II-C CRISPR-Cas9 from Neisseria meningitidis (Nme) is capable of programmable, RNA-guided, site-specific cleavage and recognition of single-stranded RNA targets, and this ribonuclease activity is independent of the PAM sequence. We define the mechanistic feature and specificity constraint for RNA cleavage by NmeCas9, and also show that nuclease-null dNmeCas9 binds to RNA target complementary to CRISPR RNA. Finally, we demonstrate that NmeCas9-catalyzed RNA cleavage can be blocked by three families of Type II-C anti-CRISPR proteins. These results fundamentally expand the targeting capacities of CRISPR-Cas9, and highlight the potential utility of NmeCas9 as a single platform to target both RNA and DNA.
