WebJan 25, 2014 · These engineered nucleases create a double-strand break (DSB) which is either repaired inaccurately by non-homologous end joining (NHEJ), an error prone process often creating insertions or deletions (indels) or, when a donor DNA is provided, can be repaired by homologous recombination (HR), thereby mediating the exchange of the … WebCurrently four families of engineered nucleases have been developed for this purpose. These include the zinc finger nucleases, meganucleases, Transcription Activator-Like Effector-based Nucleases (TALEN), and the Clustered Regularly-Interspaced Short Palindromic Repeats (CRISPR)—Cas system.

WebOct 24, 2013 · To address this issue, many different types of nucleases have been developed. All nucleases consist of 2 components – the nuclease itself that is responsible for DNA cleavage and a secondary component responsible for recognizing a specific DNA sequence. There are three main classes of nucleases engineered for genomic editing … WebHere, we report that engineered Cas9 nucleases that create different DNA break structures engage competing repair pathways at dramatically altered frequencies. We accordingly designed a Cas9 variant (vCas9) that produces breaks which suppress otherwise dominant nonhomologous end-joining (NHEJ) repair.

WebJun 2, 2024 · Improvements in the understanding of human genetics and its roles in disease development and prevention have led to an increased interest in therapeutic genome editing via the use of engineered nucleases.
