Zinc Finger Nuclease an overview | ScienceDirect Topics

Zinc fingers are small structural protein motifs that coordinate zinc, which are commonly found in proteins taking part in nucleic acid–based processes in the cell. Initially, zincfinger motifs were attributed to transcription factors; however, later they were found in many proteins interacting with DNA/RNAbinding proteins.
