Function | Ligand-activated transcriptional activator. Binds to the XRE promoter region of genes it activates. Activates the expression of multiple phase I and II xenobiotic chemical metabolizing enzyme genes (such as the CYP1A1 gene). Mediates biochemical and toxic effects of halogenated aromatic hydrocarbons. Involved in cell-cycle regulation. Likely to play an important role in the development and maturation of many tissues. Regulates the circadian clock by inhibiting the basal and circadian expression of the core circadian component PER1. Inhibits PER1 by repressing the CLOCK-ARNTL/BMAL1 heterodimer mediated transcriptional activation of PER1. {ECO:0000269|PubMed:10395741, ECO:0000269|PubMed:7961644}. |
Subcellular Location | Cytoplasm. Nucleus. Note=Initially cytoplasmic; upon binding with ligand and interaction with a HSP90, it translocates to the nucleus. |
Tissue Specificity | Expressed in all tissues tested including blood, brain, heart, kidney, liver, lung, pancreas and skeletal muscle. {ECO:0000269|PubMed:7515333, ECO:0000269|PubMed:8246913}. |
