GO Classification
Functions
drug binding / RNA polymerase II regulatory region sequence-specific DNA binding / RNA polymerase II transcription factor activity, ligand-activated sequence-specific DNA binding / steroid hormone receptor activity / transcription coactivator activity / transcriptional activator activity, RNA polymerase II transcription regulatory region sequence-specific binding / zinc ion binding
Processes
drug export / exogenous drug catabolic process / gene expression / intracellular receptor signaling pathway / negative regulation of transcription, DNA-templated / positive regulation of transcription from RNA polymerase II promoter / positive regulation of transcription, DNA-templated / signal transduction / steroid metabolic process / transcription initiation from RNA polymerase II promoter / xenobiotic metabolic process / xenobiotic transport
Components
nucleoplasm
General Function
Zinc ion binding
Specific Function
Nuclear receptor that binds and is activated by variety of endogenous and xenobiotic compounds. Transcription factor that activates the transcription of multiple genes involved in the metabolism and secretion of potentially harmful xenobiotics, drugs and endogenous compounds. Activated by the antibiotic rifampicin and various plant metabolites, such as hyperforin, guggulipid, colupulone, and isoflavones. Response to specific ligands is species-specific. Activated by naturally occurring steroids, such as pregnenolone and progesterone. Binds to a response element in the promoters of the CYP3A4 and ABCB1/MDR1 genes.
