Proteins which have DNA binding domain in its structure are
The specificity involved in the control of transcription requires that regulatory proteins bind with high affinity and specificity to the correct region of DNA. Three unique motifs--the helix-turn-helix, the zinc finger, and the leucine zipper-- account for many of these specific protein-DNA interactions.Harper 30th edition pg: 444
