SOLUTION STRUCTURE OF THE SPECIFIC DNA COMPLEX OF THE ZINC CONTAINING DNA BINDING DOMAIN OF THE ERYTHROID TRANSCRIPTION FACTOR GATA-1 BY MULTIDIMENSIONAL NMR
This domain uses four cysteine residues to coordinate a zinc ion. This domain binds to DNA. Two GATA zinc fingers are found in the GATA transcription factors. However there are several proteins which only contain a single copy of the domain.
