Aryl hydrocarbon nuclear translocator (ARNT), also commonly known as Hypoxia-inducible factor 1-beta (HIF-1 beta), is a ubiquitously expressed transcription factor that is part of the basic-helix-loop-helix (bHLH)-Per-ARNT-Sim (PAS) family (1, 2). Human arnt is located on chromosome 1q21 and encodes a protein 789 amino acids (aa) in length with a theoretical molecular weight of 87 kDa (1). Structurally, ARNT has a DNA binding bHLH domain, two PAS domains required for dimerization, and a transactivation domain/PAC region (1). ARNT belongs to the Class II bHLH-PAS proteins and is able to homodimerize or heterodimerize with the Class I proteins including AHA, AHRR, HIF-1 alpha, HIF-2 alpha, NPAS1, and SIM1 (2). Dimerization allows for efficient DNA binding and regulation of their target genes (2).

ARNT has an important role in two specific signaling pathways - the aryl hydrocarbon receptor (AhR) and the hypoxia inducible factor (HIF) pathway (1). In the AhR pathway, AhR in the cytosol is typically inactive and bound to heat shock protein 90 (hsp90) (3). Upon activation and ligand binding by environmental pollutants such as dioxins, AhR is translocated to the nucleus, dissociates from hsp90, and dimerizes with ARNT, leading to binding to response elements and expression of target genes including monooxygenases (1, 3). In the HIF pathway, under hypoxia (low oxygen) conditions prolylhydroxylase domain (PHD) enzymes and factor inhibiting HIF (FIH) are inhibited. HIF-1 alpha (or HIF-2 alpha) accumulates and is transported to the nucleus where it heterodimerizes with ARNT, allowing for binding to target gene's hypoxia response element (HRE), recruitment of coactivators, and transcription (1, 3). HIF-induced gene transcription plays a large role in tumor progression by promoting invasion, metastasis, de-differentiation and altered metabolism, and angiogenesis (1). While HIF-1 alpha's stability is dependent upon oxygen conditions, HIF-1 beta is stable in both normoxia and hypoxia (1-3).

The bHLH-PAS family and ARNT have been linked with a variety of pathologies and diseases including cancer, metabolic diseases, autoimmune diseases, and psychiatric disorders (2). ARNT/AHR is expressed in the skin and its pathway activation enhances skin barrier function and epidermal terminal differentiation, thus AHR agonists are currently being used as therapeutics for atopic dermatitis and psoriasis (4). Accordingly, studies of Arnt-deficient mice show profound abnormalities in skin barrier function and keratinization (4). Additionally, studies suggest that ARNT plays an important role in diabetes and beta-cell function (5). Islets from patients with type 2 diabetes have a significantly decreased ARNT expression compared to glucose-tolerant control donors (5). Modulation and stimulation of the HIF pathway may be a potential therapeutic strategy for treating type 2 diabetes and metabolic syndrome (5).

Alternate names for ARNT/HIF-1 beta include aryl hydrocarbon receptor nuclear translocator, BHLHE2, class E basic helix-loop-helix protein 2, Dixon receptor nuclear translocator, Hypoxia-inducible factor 1-beta, nuclear translocator, and TANGO.

FAQs for ARNT/HIF-1 beta Antibody Pack (NB100-982). (Showing 1 - 4 of 4 FAQs).

  1. Is this target appropriate for use in Chromatin Research?
    • Yes; here is a list of research areas that we have deemed appropriate for the target "ARNT/HIF-1 beta": Angiogenesis, Autophagy, Cancer, Cellular Markers, Chromatin Research, HIF Target Genes, Hypoxia, Transcription Factors and Regulators, Cardiovascular Biology, Lipid and Metabolism.
  2. For use in Western Blot with HIF-1 beta antibodies, what molecular weight of the band should I expect to see?
    • The theoretical molecular weight determined by our technical team for ARNT/HIF-1 beta antibodies is 86.6 kDa.
  3. If this product is used in an application or species as a part of a customer review, will that validate this product in the application/species?
    • If any of our primary antibodes are used in an untested application or species and it is shown to work through images from customer reviews or through publications, this validates the application/species for this product, allowing the tested application/species to fall under our 100% guarantee. Please check out our Innovator's Reward Program if you decide to test a primary antibody with a species or application that is not currently listed. Please note that the Innovator's Reward Program only applies to our primary antibodies.
  4. Would you please help confirm the components of NB100-982? If NB100-982 really contains regular sizes of these 2 antibodies (not SS), the bargain seems too great to be true. However, if it is composed of NB100-110SS and NB100-124SS, the product seems too expensive.
    • NB100-982 contains 0.1ml of NB100-110 and 0.1ml of NB100-124.
