| |
|
| | '''Gcn4''' or '''General control protein Gcn4''' is a yeast transcriptional activator. It belongs to a large family of eukaryotic transcription factors including Fos, Jun and CREB. <ref>PMID:7934812</ref> Gcn4-pLI is a 33-residue peptide of the dimerization domain of Gcn4. See also [[Intrinsically Disordered Protein]]. |

| | == Structural highlights == |
|
| |
|
| | Gcn4 and other family members have a DNA recognition motif consisting of a coiled-coil dimerization element, the leucine-zipper, and an adjoining basic region, which mediates DNA binding. This basic region is largely unstructured in the absence of DNA, addition of DNA containing a Gcn4 binding site induces the transition of this region from unstructured to α-helical. |
