Zinc Finger Nucleases (ZFNs) were the first widely used programmable DNA binding protein system. ZFNs are comprised of a chain of zinc finger proteins fused to a bacterial nuclease to produce a system capable of making site-specific double stranded DNA breaks to enable gene edits. The zinc finger proteins provide site specific targeting as they each recognize a 3–4 base pair DNA sequence.
