Background InformationCRISPR-associated endonuclease Cas9/Csn1 (UniProt: Q99ZW2; also known as SpCas9, SpyCas9, Cas9) is encoded by the Cas9 gene (Gene ID: 69900935) in Streptococcus pyogenes. CRISPR (clustered regularly interspaced short palindromic repeat) is an adaptive immune system that provides protection against mobile genetic elements (viruses, transposable elements, and conjugative plasmids). CRISPR clusters contain spacers, sequences complementary to antecedent mobile elements, and target invading nucleic acids. Cas9 has a bi-lobed architecture with a recognition lobe (residues 41-425) and a discontinuous nuclease lobe (NUC, residues 1-40 and 453-1053); the crRNA-target DNA lies in a channel between the 2 lobes. The NUC lobe has 2 endonuclease domains. The discontinuous RuvC-like domain in NUC cleaves the target DNA non-complementary to crRNA while the HNH nuclease domain cleaves the target DNA complementary to crRNA. Cas9 serves as a RNA-guided DNA endonuclease that cleaves double-stranded DNA targets with a protospacer adjacent motif (PAM) and complementarity to the guide RNA. (Ref.: Fonfara, I., et al. (2014). Nucleic Acids Res. 42(4); 2577-2590; Jinek, M., et al. (2012). Science. 337(6096); 816-821).
