zinc fin·ger

a zinc-binding domain in a protein structure often seen in certain gene regulatory proteins, for example, transcription factors.
Farlex Partner Medical Dictionary © Farlex 2012
A small tertiary protein structural motif of higher organisms, in which parts of a protein fold around a zinc molecule, acting as a hook to attach activator proteins to DNA; the ZF motif is present in many proteins that regulate expression of eukaryotic genes—e.g., proto-oncogenes, Wilms’ tumour gene, growth signal receptors

zinc finger

a finger-like structure that is found in specific DNA binding PROTEINS, where the DNA binding DOMAIN of the protein complexes zinc. Zinc fingers are found in various eukaryotic TRANSCRIPTION factors, which have a role in controlling the transcription of specific GENES.
