A zinc finger DNA-binding motif is common to many transcription factors in the human genome.
The first zinc finger motifs were identified in the structure of Xenopus transcription factor IIIA in 1985. This motif consists of a relatively short α-helix and a two-stranded antiparallel β-sheet.
Proteins has unique features, They binds to DNA as homodimers or heterodimers and recognize DNA through one of a small number of structural motifs. Their are other common motifs in transcriptional activator proteins that include the helix-turn-helix, the homeodomain, the leucine zipper, the helix-loop-helix, and zinc fingers of many types.
