The Aryl hydrocarbon receptor (AHR) is a member of the basic helix–loop–helix–PER– ARNT–SIM (bHLH–PAS) subgroup of the bHLH superfamily of transcription factors and is the only member of this family known to be activated by ligands. Those ligands can be endogenous, naturally occurring, and/or anthropogenic. In vitro studies and gene expression profiles showed that the transcriptional changes by the activated Ahr are ligand specific and are highly cell specific. There is only one ligand binding pocket in the AHR (in the Per-ARNT-Sim-B domain), and the affinity of the best characterized high affinity ligand, TCDD (2,3,7,8-tetrachlorodibenzo-pdioxin), depends on only a few amino acids in that pocket. The Ahr can also be activated by numerous stress factors and substances that may not fit into the binding pocket, such as hyperoxia, oxidized low-density lipoproteins, hydrogen peroxide, ozone, and metals. Ahr regulates genes involved in a wide variety of biochemical pathways, including energy metabolism, lipid and cholesterol synthesis, xenobiotic metabolism and various transporters. The Ahr is well known to be involved in a variety of cellular processes, such as the cell cycle, epithelial barrier function, cell migration, and immune function.Product Details

AB_2650731 (BioLegend Cat. No. 694502)
- 848 amino acids with a predicted molecular weight of 95 kD.
Cytoplasm and nucleus.
- 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. 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.
- In the nucleus, heterodimer of AHR and ARNT. Interacts with coactivators including SRC-1, RIP140 and NOCA7, and with the corepressor SMRT. Interacts with MYBBP1A, NEDD8, ARNTL/BMAL1.
- Hydrophobic aromatic compound.
