Arnt 2 Rabbit Polyclonal Antibody

Aryl hydrocarbon receptor nuclear translocator 2 (ARNT2) Homo sapiens 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. [provided by RefSeq, Dec 2013], function:Specifically recognizes the xenobiotic response element (XRE) ., similarity:Contains 1 basic helix-loop-helix (bHLH) domain., similarity:Contains 1 PAC (PAS-associated C-terminal) domain., similarity:Contains 2 PAS (PER-ARNT-SIM) domains., subunit:Efficient DNA binding requires dimerization with another bHLH protein. Heterodimer with the aryl hydrocarbon receptor (AHR) or the SIM1 protein. Interacts with TACC3.
