 Upon binding the transformed receptor translocates to the nucleus where it dimerises with ARNT (aryl hydrocarbon receptor nuclear translocator) and then binds xenobiotic response elements (XREs) in DNA located upstream of certain genes.This process increases transcription of certain genes, notably "CYP1A1", followed by increased CYP1A1 protein production.This process is similar to induction of CYP1A1 by certain polychlorinated biphenyls and dioxins.
