Abstract
Gel retardation analysis has been utilized to examine the ability of transformed hepatic cytosolic TCDD:AhR complex to bind to its specific DNA recognition site, the dioxin responsive element (DRE). Although DRE sequence alignment has identified a conserved DNA recognition sequence of C/GNNNC/GTNGCGTGNC/GT/ANNNC/G, site-directed mutagenesis has demonstrated that not all of these bases are important for DNA binding. A putative TCDD:AhR DRE-binding consensus of GCGTGNNA/TNNNG/C has been derived from our studies and it is highly conserved among species. In addition, we present a model for the DNA-binding of transformed TCDD:AhR complex.
