Abstract custom-designed zinc finger nucleases (zfns), proteins designed to cut at specific dna sequences, are becoming powerful tools in gene targeting—the. Zinc finger-type proteins broadly play a critical role not only in many cellular functions as tfs, but also in many biological events such as rna binding, regulation of apoptosis, and protein-protein interactions.

Zinc finger domains are one of the most common structural motifs in eukaryotic cells, which employ the motif in some of their most important proteins (including tfiiia, ctcf, and zif268) these dna binding proteins contain up to 37 zinc finger domains connected by flexible linker regions. Abstract zinc is a catalytic, structural and regulatory ion involved in a wide variety of biological processes it is essential for stabilising the fold of biomolecules called ‘zinc finger’, a term that originates from the finding of the particular organisation of zinc coordinating amino‐acids in the primary sequence of the tfiiia transcription factor. Zinc-finger nucleases (zfns) are targetable dna cleavage reagents that have been adopted as gene-targeting tools zfn-induced double-strand breaks are subject to cellular dna repair processes that lead to both targeted mutagenesis and targeted gene replacement at remarkably high frequencies this . Athletes with strong immune systems are better able to fight off sickness, but also have improved recovery times from exercise must bind to dna via zinc fingers .
