WebApr 14, 2024 · The classic CRISPR-Cas9 system uses a DNA-cutting protein called Cas9 found in bacterial immune systems. The system can be targeted to specific genes in human cells using a single guide RNA, where the Cas9 proteins create tiny breaks in the DNA strand. Then the cell’s existing repair machinery patches up the holes. WebOther CRISPR systems, specifically the Type VI CRISPR enzymes Cas13a/C2c2 and Cas13b, target RNA rather than DNA. Fusing a hyperactive adenosine deaminase that acts on RNA, ADAR2(E488Q), to catalytically dead Cas13b creates a programmable RNA base editor that converts adenosine to inosine in RNA (termed REPAIR). Since inosine is …
