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. CRISPR clusters are transcribed and processed into CRISPR RNA (crRNA). In type II CRISPR systems correct processing of pre-crRNA requires a trans-encoded small RNA (tracrRNA), endogenous ribonuclease 3 (rnc) and Cas9. The tracrRNA serves as a guide for ribonuclease 3-aided processing of pre-crRNA (Probable). Cas9/crRNA/tracrRNA endonucleolytically cleaves linear or circular dsDNA target complementary to the spacer yielding blunt ends; Cas9 is inactive in the absence of the 2 guide RNAs (gRNA). Cas9 recognizes a 3'-G-rich protospacer adjacent motif (PAM, TGGTG in this organism) in the CRISPR repeat sequences to help distinguish self versus nonself, as targets within the bacterial CRISPR locus do not have PAMs. PAM recognition is also required for catalytic activity. When the CRISPR3/cas system consisting of cas9-cas1-cas2-csn2-CRISPR3 or just cas9-CRISPR3 is expressed in E.coli it prevents plasmids homologous to spacers 1 or 2 from transforming.

CRISPR-Cas9 also known simply as Cas9 is a protein that acts as a molecular scissor in gene editing. It has a molecular weight of approximately 160 kDa. Cas9 is a part of the CRISPR-Cas system originally discovered in bacteria where it serves as an adaptive immune system. In bacterial cells Cas9 targets and cleaves specific DNA sequences allowing for targeted gene modifications. While the expression of the CRISPR-Cas system occurs naturally in prokaryotes scientists now harness it in various organisms for genetic manipulation.
The Cas9 protein functions as an integral part of the CRISPR-Cas9 complex which includes a guide RNA to direct the protein to specific DNA sequences. This complex enables precise cuts at targeted locations within the genome. The Cas9 protein size allows it to fit effectively within cells facilitating genome editing in areas such as research agriculture and therapeutics. The complexity of CRISPR-Cas9 also includes the interaction with other cellular components that assist in DNA repair post-cleavage.
CRISPR-Cas9 plays a role in DNA repair pathways particularly non-homologous end joining and homologous recombination. After Cas9-induced DNA breaks these pathways become active to repair the cleaved DNA. The gene editing process facilitated by CRISPR-Cas9 often involves interaction with DNA repair proteins like ku70/80 and Rad51 in response to induced breaks. This allows for either the incorporation of new genetic material or the modification of existing genes.
CRISPR-Cas9 has potential in treating genetic disorders such as cystic fibrosis and Duchenne muscular dystrophy. By correcting mutated genes scientists aim to restore normal gene function offering potential therapeutic benefits. Additionally CRISPR-Cas9 relates indirectly to p53 a protein known for its tumor suppressor functions because gene-editing processes can sometimes activate p53-dependent pathways leading to cell cycle arrest or apoptosis. This highlights the importance of understanding the broader implications of CRISPR-Cas9 in therapeutic applications.
