Zinc-finger 1

The “finger” refers to the secondary structures (α-helix and β-sheet) that are held together by the .
Function
This small protein motif is a transcriptional regulator. It 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. regulate eukaryotic gene expression
Interactions
The zinc-fingers usually interact with the outside of B-DNA. When interacting with DNA, the zinc fingers bind in the major groove of B-DNA and wrap part way around the double helix.
