title: Functional dissection of AP-1 transcription factors using the Gal4 adaptor assay.
abstract: In the Gal4 adaptor assay, leucine zipper-containing proteins are tethered indirectly to the promoters of Gal4-responsive reporter genes via synthetic protein chimeras consisting of a Gal4 DNA-binding domain with an attached leucine zipper. Ternary complexes composed of the DNA binding site, the adaptor protein, and a leucine zipper factor can stimulate reporter gene activity, provided that the latter component possesses a transcriptional activation domain. This system is used to assay the transcriptional function and the interactions between various AP-1 factors.
