RXRA-B

Targets RXRA and RXRB. Retinoic acid receptor RXR-alpha/beta. Receptor for retinoic acid that acts as a transcription factor (PubMed:10383391, PubMed:12032153, PubMed:25417649). Forms homo- or heterodimers with retinoic acid receptors (RARs) and binds to target response elements in response to their ligands, all-trans or 9-cis retinoic acid, to regulate gene expression in various biological processes (PubMed:1310259, PubMed:10383391). The RAR/RXR heterodimers bind to the retinoic acid response elements (RARE) composed of tandem 5'-AGGTCA-3' sites known as DR1-DR5 to regulate transcription (PubMed:1310259). The high affinity ligand for retinoid X receptors (RXRs) is 9-cis retinoic acid (PubMed:10383391, PubMed:25417649). In the absence of ligand, the RXR-RAR heterodimers associate with a multiprotein complex containing transcription corepressors that induce histone deacetylation, chromatin condensation and transcriptional suppression (By similarity). On ligand binding, the corepressors dissociate from the receptors and coactivators are recruited leading to transcriptional activation (By similarity). Serves as a common heterodimeric partner for a number of nuclear receptors, such as RARA, RARB and PPARA (PubMed:1310259). The RXRA/RARB heterodimer can act as a transcriptional repressor or transcriptional activator, depending on the RARE DNA element context (By similarity). (Source UniProtKB)
