Structural and functional characterization of the short acidic transcriptional activation region of yeast GCN4 protein

Nature. 1988 Jun 16;333(6174):635-40. doi: 10.1038/333635a0.


Derivatives of the yeast GCN4 transcription factor containing acidic regions of 35 to 40 amino acids fused directly to the DNA-binding domain are fully functional in vivo. High resolution deletion analysis and proteolytic mapping suggest that the activation region is a repeated structure composed of small units acting additively. Acidic character is a feature of the structural motif, possibly a dimer of alpha-helices from two GCN4 monomers, that may be important for interactions with the basic transcriptional machinery.
