Previous GeneCards Identifiers for ARNT Gene
This gene encodes a protein containing a basic helix-loop-helix domain and two characteristic PAS domains along with a PAC domain. The encoded protein binds to ligand-bound aryl hydrocarbon receptor and aids in the movement of this complex to the nucleus, where it promotes the expression of genes involved in xenobiotic metabolism. This protein is also a co-factor for transcriptional regulation by hypoxia-inducible factor 1. Chromosomal translocation of this locus with the ETV6 (ets variant 6) gene on chromosome 12 have been described in leukemias. Alternative splicing results in multiple transcript variants.

GeneCards Summary for ARNT Gene
ARNT (Aryl Hydrocarbon Receptor Nuclear Translocator) is a Protein Coding gene. Diseases associated with ARNT include Hypoxia. Among its related pathways are Cytochrome P450 - arranged by substrate type and Translational Control. Gene Ontology (GO) annotations related to this gene include DNA binding transcription factor activity and protein heterodimerization activity. An important paralog of this gene is ARNT2.
UniProtKB/Swiss-Prot for ARNT Gene
Required for activity of the Ah (dioxin) receptor. This protein is required for the ligand-binding subunit to translocate from the cytosol to the nucleus after ligand binding. The complex then initiates transcription of genes involved in the activation of PAH procarcinogens. The heterodimer with HIF1A or EPAS1/HIF2A functions as a transcriptional regulator of the adaptive response to hypoxia.
