背景信息

**Background of ARNT2 Recombinant Protein**

ARNT2 (Aryl Hydrocarbon Receptor Nuclear Translocator 2) is a member of the basic helix-loop-helix-Per-Arnt-Sim (bHLH-PAS) protein family, which plays critical roles in transcriptional regulation and cellular responses to environmental cues. It functions as a dimerization partner for other bHLH-PAS transcription factors, such as hypoxia-inducible factors (HIFs) and single-minded proteins (SIMs), forming heterodimeric complexes that bind to specific DNA sequences to regulate target gene expression. Unlike its paralog ARNT1. ARNT2 exhibits tissue-specific expression, predominantly in the brain, kidneys, and endocrine tissues, suggesting specialized roles in neurodevelopment, metabolism, and hormonal signaling.

Recombinant ARNT2 protein is produced using genetic engineering techniques, often expressed in bacterial, yeast, or mammalian systems, followed by purification to ensure high specificity and activity. This engineered protein enables researchers to study ARNT2’s molecular interactions, structural features, and regulatory mechanisms in vitro or in cellular models. For example, it aids in mapping binding interfaces with partners like HIF-2α or SIM1. elucidating pathways involved in hypoxia response, circadian rhythm regulation, or neuronal differentiation.

ARNT2 dysfunction is linked to neurodevelopmental disorders, including autism spectrum disorders and intellectual disabilities, as well as cancers and metabolic diseases. Recombinant ARNT2 serves as a vital tool for drug discovery, screening therapeutic agents targeting ARNT2-dependent pathways, and developing gene therapies. Its study also contributes to understanding tissue-specific transcriptional networks and adaptive cellular responses, bridging gaps between basic research and clinical applications.
