FUNCTION: The protein encoded by this gene is a ligand-activated helix-loop-helix transcription factor involved in the regulation of biological responses to planar aromatic hydrocarbons. This receptor has been shown to regulate xenobiotic-metabolizing enzymes such as cytochrome P450. Before ligand binding, the encoded protein is sequestered in the cytoplasm; upon ligand binding, this protein moves to the nucleus and stimulates transcription of target genes. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2015]
PHENOTYPE: Homozygotes for null or hypomorphic alleles do not respond to cyclic compounds (e.g., dioxin) and are resistant to their teratogenic effects. Depending on the allele, null mutants may also have liver defects, impaired female fertility, neonatal or postnatal lethality, and spleen abnormalities. [provided by MGI curators]
