"Discovery: Fanzor, a Programmable RNA-Guided Endonuclease, Unveils Animal's CRISPR-Like System for Editing Human Genome"

Researchers have discovered a new class of RNA-guided endonuclease called Fanzor, which is found in eukaryotes. Fanzor has the ability to cleave DNA and can be reprogrammed for genome engineering applications in humans. The structure of Fanzor has been resolved, revealing its similarity to other RNA-guided systems like Cas12. This discovery demonstrates that RNA-guided endonucleases are present in all three domains of life.
