Retinoic acid receptor RXR-alpha (UniProt: P19793; also known as Nuclear receptor subfamily 2 group B member 1, Retinoid X receptor alpha) is encoded by the RXRA (also known as NR2B1) gene (Gene ID: 6256) in human. RXR-alpha is a homodimeric protein that can also for heterodimer with RAR-alpha via its C-terminal. RXR-alpha serves as a receptor for retinoic acid and binds to target response elements in response to their ligands, all-trans or 9-cis retinoic acid, to regulate the expression of genes involved in various biological processes. 9-cis retinoic acid is considered as a high affinity ligand of RXR-alpha. The RAR/RXR heterodimers are reported to bind to the retinoic acid response elements (RARE) composed of tandem 5′-AGGTCA-3′ sites known as DR1-DR5 to regulate transcription. In the absence of ligand, the RXR-RAR heterodimers associate with a multiprotein complex containing transcription co-repressors that induce histone deacetylation, chromatin condensation and transcriptional suppression. On ligand binding, the corepressors dissociate from the receptors and coactivators are recruited leading to transcriptional activation. RXR-alpha is highly expressed in liver and its expression has also been reported in lung fibroblasts, monocytes, kidney, and brain. RXR-alpha is composed of three domains: a modulating N-terminal domain (AF1 domain), a DNA-binding domain, and a C-terminal ligand-binding domain (AF2 domain). Its DNA binding region is localized to amino acids 135-200. It has two NR-C4 type zinc-finger domains (aa 135-155 and 171-195). Its nuclear localization signal is localized to amino acids 160-165 and the region comprising of amino acids 348-367 is essential for its nuclear export. Its nuclear localization is enhanced by vitamin D3. Its acetylation by EP300 is shown to enhance its DNA-binding and transcriptional activity. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
