Function

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. [1] 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.

See Coiled coil.
