Biological function summary
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.
Pathways
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.
