Description:
The Aryl Hydrocarbon Receptor (AHR), also known as the dioxin receptor, is a ligand-activated helix/loop/helix transcription factor found in a variety of vertebrate species. The known ligands for AHR are foreign planar aromatic compounds, such as polycyclic aromatic compounds and halogenated aromatic compounds such as 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD).

Research Backgrounds

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. The heterodimer ARNT:AHR binds to core DNA sequence 5'-TGCGTG-3' within the dioxin response element (DRE) of target gene promoters and activates their transcription.

PTMs:

Mono-ADP-ribosylated, leading to inhibit transcription activator activity of AHR.

Subcellular Location:

Cytoplasm. Nucleus.
Note: Initially cytoplasmic; upon binding with ligand and interaction with a HSP90, it translocates to the nucleus.

Extracellular region or secreted Cytosol Plasma membrane Cytoskeleton Lysosome Endosome Peroxisome ER Golgi apparatus Nucleus Mitochondrion Manual annotation Automatic computational assertionSubcellular location
Tissue Specificity:

Expressed in all tissues tested including blood, brain, heart, kidney, liver, lung, pancreas and skeletal muscle. Expressed in retinal photoreceptors.

Subunit Structure:

Homodimer (By similarity). Binds MYBBP1A (By similarity). Efficient DNA binding requires dimerization with another bHLH protein. Interacts with coactivators including SRC-1, RIP140 and NOCA7, and with the corepressor SMRT. Interacts with NEDD8 and IVNS1ABP. Interacts with ARNTL/BMAL1. Interacts with HSP90AB1 (By similarity). Interacts with ARNT; the heterodimer ARNT:AHR binds to core DNA sequence 5'-TGCGTG-3' within the dioxin response element (DRE) of target gene promoters and activates their transcription. Interacts with TIPARP; leading to mono-ADP-ribosylation of AHR and subsequent inhibition of AHR.

Family&Domains:

The PAS 1 domain is essential for dimerization and also required for AHR:ARNT heterodimerization.

(C and D) The antagonist CH223191 effectively suppressed AhR protein expression and relative intensity in the mammary gland (n = 3). (E) Representative H&E images among the different groups indicated that the antagonism of AhR abolished the protective function of 5-HIAA (n = 7; scale bar, 50 μm). (F) Histopathological score of the mammary gland (n = 6). (G–I) CH223191 treatment increased TNF-α (G), IL-1β (H), and MPO activity (I) in comparison to Vag+5-HIAA treatment (n = 7). (J–M) Pretreatment with CH223191 reduced the expression and relative intensity of TJ proteins ZO-1, Occludin, and Claudin-3 (n = 3). (N) The expression location and level of TJ protein were detected by immunohistochemistry (scale bar, 20 μm). (O and P) Pretreatment with CH223191 eliminated the decreasing effect of 5-HIAA on TNF-α and IL-1β mRNA levels in LPS-induced mouse mammary epithelial cells (n = 6). Data are presented as means ± SDs, and one-way ANOVA was performed for statistical analysis. ∗p < 0.05; ∗∗p < 0.01; ∗∗∗p < 0.001; and ∗∗∗∗p < 0.0001 indicate significant differences.
