ZINC FINGER-DNA RECOGNITION: CRYSTAL STRUCTURE OF A ZIF268-DNA COMPLEX AT 2.1 ANGSTROMS

Structural highlights

1zaa is a 3 chain structure with sequence from Mus musculus. The March 2007 RCSB PDB Molecule of the Month feature on Zinc Fingers by David S. Goodsell is 10.2210/rcsb_pdb/mom_2007_3. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.

Function

[EGR1_MOUSE] Transcriptional regulator. Recognizes and binds to the DNA sequence 5'-CGCCCCCGC-3'(EGR-site). Activates the transcription of target genes whose products are required for mitogenesis and differentiation.

Publication Abstract from PubMed

The zinc finger DNA-binding motif occurs in many proteins that regulate eukaryotic gene expression. The crystal structure of a complex containing the three zinc fingers from Zif268 (a mouse immediate early protein) and a consensus DNA-binding site has been determined at 2.1 angstroms resolution and refined to a crystallographic R factor of 18.2 percent. In this complex, the zinc fingers bind in the major groove of B-DNA and wrap part way around the double helix. Each finger has a similar relation to the DNA and makes its primary contacts in a three-base pair subsite. Residues from the amino-terminal portion of an alpha helix contact the bases, and most of the contracts are made with the guanine-rich strand of the DNA. This structure provides a framework for understanding how zinc fingers recognize DNA and suggests that this motif may provide a useful basis for the design of novel DNA-binding proteins.
