System cas9. Medical search. Frequent questions

The CRISPR/Cas9 system consists of two components: Cas9 protein and guide RNA (gRNA). (nature.com)
The natural Cas9 protein possesses a nuclease activity and can induce a DNA double-strand break (DSB) in any genomic sequence guided by a gRNA, provided that a protospacer adjacent motif (PAM) sequence exists in the target locus 3 , 4 , 5 . (nature.com)
Streptococcus pyogenes Cas9 (SpCas9) has been the most widely used Cas9 protein and its PAM sequence is 5′-NGG-3′, which is the only restriction for designing CRISPR/Cas9 target sequences 6 . (nature.com)
Since Cas9 has no DNA recognition specificity except for the PAM sequence, simple multiplication of gRNAs along with a common Cas9 protein results in multiplex genome engineering. (nature.com)

Apart from its original function in bacterial immunity, the Cas9 protein has been heavily utilized as a genome engineering tool to induce site-directed double-strand breaks in DNA. (wikipedia.org)
