Schematic of a Cys2His2zinc-finger motif. Each finger comprises ∼30amino acidsfolded into a ββα-configuration. Azinc ionis coordinated within the fold using two cysteine (C) and twohistidine(H) residues. Amino acid residues at positions −1, 2, 3 and 6 relative to the α-helix ...
The zinc-finger motif was discoveredduring biochemical studies on the transcription factor TFIIIA, which regulates the 5S ribosomal RNA genes of. Zinc-fingers mostly interact with DNA, but TFIIIA binds not only specifically to the promoter DNA, but also to 5S RNA itself. Increasing evidence ...
