the most commonly identified DNA-binding domain in humans
Zinc-finger motifs are composed of chains of amino acids bound together around a zinc atom via linkages with cysteine (and sometimes histidine) residues. This forms a stable, finger-shaped structure containing 2 antiparallel β- strands and an α- helix.
Many ☆transcription factors(→ intracellular receptors) use multiple zinc-finger motifs to recognize specific genes and alter their activity.
