CC -!- FUNCTION: CRISPR (clustered regularly interspaced short CC palindromic repeat) is an adaptive immune system that provides CC protection against mobile genetic elements (viruses, transposable CC elements and conjugative plasmids). CRISPR clusters contain CC spacers, sequences complementary to antecedent mobile elements, CC and target invading nucleic acids. CRISPR clusters are transcribed CC and processed into CRISPR RNA (crRNA). In type II CRISPR systems CC correct processing of pre-crRNA requires a trans-encoded small RNA CC (tracrRNA), endogenous ribonuclease 3 (rnc) and this protein. The CC tracrRNA serves as a guide for ribonuclease 3-aided processing of CC pre-crRNA. Subsequently Cas9/crRNA/tracrRNA endonucleolytically CC cleaves linear or circular dsDNA target complementary to the CC spacer; Cas9 is inactive in the absence of the 2 guide RNAs CC (gRNA). Cas9 recognizes the protospacer adjacent motif (PAM) in CC the CRISPR repeat sequences to help distinguish self versus CC nonself, as targets within the bacterial CRISPR locus do not have CC PAMs. PAM recognition is also required for catalytic activity. CC {ECO:0000255|HAMAP-Rule:MF_01480, ECO:0000269|PubMed:22745249}. CC -!- COFACTOR: CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence={ECO:0000305}; CC Note=Endonuclease activity on target dsDNA requires Mg(2+). CC {ECO:0000305}; CC -!- SUBUNIT: Monomer (By similarity). Binds crRNA and tracrRNA. CC {ECO:0000255|HAMAP-Rule:MF_01480, ECO:0000269|PubMed:22745249}. CC -!- DOMAIN: Has 2 endonuclease domains. The discontinuous RuvC-like CC domain cleaves the target DNA noncomplementary to crRNA while the CC HNH nuclease domain cleaves the target DNA complementary to crRNA. CC {ECO:0000255|HAMAP-Rule:MF_01480}. CC -!- BIOTECHNOLOGY: The simplicity of the Cas9-gRNAs RNA-directed DNA CC endonuclease activity may be used to target and modify a DNA CC sequence of interest. CC -!- SIMILARITY: Belongs to the CRISPR-associated protein Cas9 family. CC Subtype II-A subfamily. {ECO:0000305}.
