Zinc finger nuclease

Definition

Zinc finger nucleases (ZFNs) are synthetic proteins used for gene targeting. They consist of a DNA-cutting endonculease domain fused to zinc finger domains engineered to bind a specific DNA sequence. ZFNs are used to introduce insertions or deletions at cut sites in the genomes of living cells.

    Advances in genome sequencing, editing and synthetic biology have enhanced the feasibility of large-scale genome engineering, termed genome writing. In this Opinion article, Chari and Church discuss the strengths and limitations of diverse strategies for genome writing, including extensively modifying existing genomes versus synthesizing genomes de novo, and they provide future visions for writing large genomes.

    Programmable nucleases — including ZFNs, TALENs and RGENs derived from the prokaryotic CRISPR–Cas system — enable targeted high-precision genome engineering. This Review summarizes current knowledge of nuclease-specific features, individual pros and cons, and approaches to improve the efficiency of these enzymes to help researchers to choose the most appropriate tool for various genome editing experiments and applications.
