GAGA factor Members of this family bind to a 5'-GAGAG-3' DNA consensus binding site, and contain a Cys2-His2 zinc finger core as well as an N-terminal extension containing two highly basic regions. The zinc finger core binds in the DNA major groove and recognizes the first three GAG bases of the consensus in a manner similar to that seen in other classical zinc finger-DNA complexes. The second basic region forms a helix that interacts in the major groove recognising the last G of the consensus, while the first basic region wraps around the DNA in the minor groove and recognizes the A in the fourth position of the consensus sequence.
