Over the last decade programmable DNA binding proteins have been developed that can guide a nuclease to cut at any targeted point in the genome.

The Zinc Finger Nuclease (ZFN) technique uses natural proteins that bind to DNA in a sequence-specific way, allowing the fused nuclease to cut as aDNA scissorat that specific location.

This system consists of:

  • a “Zinc Finger” domain (recognising a sequence of specific base pairs triplets in the DNA sequence)
  • a nuclease that cuts double-stranded DNA
