How does the Cpf1 nuclease differ from Cas9 in CRISPR gene editing?

Created from Britannica articles using AI. AI can make mistakes, so verify using Britannica articles.

In the field of biotechnology, the Cpf1 nuclease differs from the Cas9 enzyme in two primary ways regarding its function in CRISPR gene editing:

  • Guide RNA requirement: Unlike Cas9, which typically requires a more complex setup, Cpf1 requires only a single CRISPR guide RNA to achieve specificity.12
  • Cleavage pattern: Cas9 introduces blunt cuts in double-stranded DNA, whereas Cpf1 introduces staggered cuts.12

These distinct properties allow Cpf1 to offer researchers greater control over the modification of target DNA sequences in certain experimental circumstances. Both nucleases are essential tools in gene editing, a technology that enables precise alterations to the genetic makeup of living organisms to study or potentially treat human disease.12
