Abstract excerpt
The phenobarbital (PB) responsive enhancers in CYP2B genes contain a core of two direct repeat-4 nuclear receptor binding sites, NR-1 and NR-2, which flank an NF-1 site and appear to be most important for PB responsiveness. Additional sequences outside the core are required for maximal PB responsiveness, including a third direct repeat-4 site, NR-3. The PB response is mediated by constitutive androstane receptor...
