Zinc fingers in biological systems
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 .

- Zinc finger proteins were discovered in 1985 by sir aaron klug at the mrc laboratory of molecular biology in studies aimed at shedding light on the fundamental processes of gene transcription and regulation zinc finger proteins were thus named because they grip dna molecules like a ‘finger’ and have a zinc molecule within its folds.
