Fanzor DNA Cutters: A Potential CRISPR Challenger

Thousands of DNA-cutting enzymes called Fanzors, similar to CRISPR, have been discovered in various eukaryotic species, including snails, algae, and amoeba. These RNA-guided enzymes have the potential to be developed into tools for gene editing in medicine and biotechnology. The researchers hope that Fanzors, which are naturally evolved in eukaryotes, will provide a safer and more efficient genome editing system for humans. The Fanzor system is more compact than CRISPR proteins, making it easier to deliver to cells and tissues, and may have fewer off-target effects. The discovery of Fanzors opens up new possibilities for RNA-guided biology and the development of novel gene editing tools.
