A novel clustered regularly interspaced short palindromic repeats/CRISPR-associated (CRISPR/Cas) tool for simultaneous gene editing and regulation was designed and tested. This study used the CRISPR-associated protein 9 (Cas9) endonuclease in complex with a 14-nucleotide (nt) guide RNA (gRNA) to repress a gene of interest using the Krüppel associated box (KRAB) domain, while also performing a separate gene modification using a 20-nt gRNA targeted to a reporter vector. DNA Ligase IV (LIGIV) was chosen as the target for gene repression, given its role in nonhomologous end joining, a common DNA repair process that competes with the more precise homology-directed repair (HDR). …
