The transcription factor AP-1 activates the expression of numerous genes in response to mitogenic stimuli. AP-1 regulates gene expression both through solitary binding to independent recognition sites and, in cooperation with various heterologous transcription factors, through targeting to composite response elements. The two subunits that make up the AP-1 heterodimer, Fos and Jun, possess identical residues at positions that make sequence-specific contacts to DNA. This degeneracy leaves the protein with no apparent way of orienting itself uniquely on DNA by differentially recognizing its two non-identical half-sites. Here, we have analyzed the orientation of the AP-1 basic-leucine-zipper (bZip) domain on a cognate site, both alone and in the cooperative complex formed together with the 'nuclear factor of activated T cells' (NFATp).
