Summary: This gene encodes a member of the basic-helix-loop-helix-Per-Arnt-Sim (bHLH-PAS) superfamily of transcription factors. The encoded protein acts as a partner for several sensor proteins of the bHLH-PAS family, forming heterodimers with the sensor proteins that bind regulatory DNA sequences in genes responsive to developmental and environmental stimuli. Under hypoxic conditions, the encoded protein complexes with hypoxia-inducible factor 1alpha in the nucleus and this complex binds to hypoxia-responsive elements in enhancers and promoters of oxygen-responsive genes. A highly similar protein in mouse forms functional complexes with both aryl hydrocarbon receptors and Single-minded proteins, suggesting additional roles for the encoded protein in the metabolism of xenobiotic compounds and the regulation of neurogenesis, respectively.

Structures of NPAS4-ARNT and NPAS4-ARNT2 heterodimers reveal new dimerization modalities in the bHLH-PAS transcription factor family.
Title: Structures of NPAS4-ARNT and NPAS4-ARNT2 heterodimers reveal new dimerization modalities in the bHLH-PAS transcription factor family.
The meta-analysis of both populations showed that carriers of the ARNT2 rs1374213G, CX3CR1 rs7631529A, and CX3CR1 rs9823718G alleles (where the RefSeq identifier appears as a subscript) had a significantly increased risk of developing invasive aspergillosis according to a log-additive model.
Title: Polymorphisms within the ARNT2 and CX3CR1 Genes Are Associated with the Risk of Developing Invasive Aspergillosis.
Immunohistochemistry confirmed ARNT2 expression in cell sub-populations within proliferative zones of patients' glioblastoma. Decreased ARNT2 expression was consistently observed in non-tumorigenic glioblastoma cells, compared to tumorigenic cells. Moreover, ARNT2 expression correlated with a tumorigenic molecular signature at both the tissue level within the tumor core and at the single cell level in the patients' tumors
Title: Changes in chromatin state reveal ARNT2 at a node of a tumorigenic transcription factor signature driving glioblastoma cell aggressiveness.
Low expression of ARNT2 is associated with gastric cancer.
Title: Overexpression of ARNT2 is associated with decreased cell proliferation and better prognosis in gastric cancer.
The single nucleotide polymorphisms rs4778599 in the gene encoding aryl hydrocarbon receptor nuclear translocator 2 (ARNT2), showed an association that survived correction for multiple testing with emotion recognition of audio-visual stimuli in women
Title: Emotion recognition associated with polymorphism in oxytocinergic pathway gene ARNT2.
Attenuated ARNT2 expression in HCC827 cells greatly promoted tumor growth.
Title: ARNT2 is downregulated and serves as a potential tumor suppressor gene in non-small cell lung cancer.
nominal associations were found between autism spectrum disorder scores and single-nucleotide polymorphisms in OXT, ARNT2 and CD38
Title: Associations between oxytocin-related genes and autistic-like traits.
Data suggest that selected human SIM1 (single-minded homolog 1) variants exhibit poor dimerization with ARNT2 and anomalous intracellular localization; these data were used to predict 'hot-spot' in SIM1/SIM2 (residues 290-326) critical for function.
Title: Characterization of human variants in obesity-related SIM1 protein identifies a hot-spot for dimerization with the partner protein ARNT2.
These results provide insight into the mechanisms of NPAS4/ARNT dimerisation and transcriptional activation.
Title: Human variants in the neuronal basic helix-loop-helix/Per-Arnt-Sim (bHLH/PAS) transcription factor complex NPAS4/ARNT2 disrupt function.
mutation of ARNT2 results in absence of detectable levels of ARNT2 transcript and protein from patient fibroblasts compared with controls, consistent with nonsense-mediated decay of the mutant transcript and loss of ARNT2 function.
Title: ARNT2 mutation causes hypopituitarism, post-natal microcephaly, visual and renal anomalies.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
