Scientists have categorized different types of CRISPR systems<\/a> into two classes based on how their Cas nucleases function. In class 1 (types I, III, and IV), different Cas proteins form a complex machinery to identify and cut foreign DNA; in class 2 CRISPR systems (types II, V, and VI), a single Cas protein effector recognizes and cleaves DNA.9<\/sup><\/p>\n

After characterizing CRISPR\u2019s role as a defense mechanism in bacteria, researchers soon realized that they could harness this system for gene manipulation in any cell. All they needed to do was design a CRISPR gRNA sequence that bound to a specific DNA sequence and triggered the Cas nuclease, which would then cut precisely at that location. With CRISPR, researchers routinely knock out gene function by cutting out a DNA fragment, or they insert a desired genetic sequence into the genome by providing a reference DNA template along with the CRISPR components. While editing eukaryotic cells has been the focus for tackling diseases, many researchers now use CRISPR to edit bacterial communities.<\/p>\n

\u201cIt\u2019s almost like back to the beginning or back to the origins. There\u2019s some irony in bringing CRISPR back to where it came from,\u201d said Rodolphe Barrangou<\/a>, a functional genomics researcher at North Carolina State University, who helped characterize the immune function of CRISPR and has been working with it for more than 20 years.<\/p>\n","protected":false},"excerpt":{"rendered":"
