| [[http://www.uniprot.org/uniprot/RXRA_MOUSE RXRA_MOUSE]] Receptor for retinoic acid. Retinoic acid receptors bind as heterodimers to their target response elements in response to their ligands, all-trans or 9-cis retinoic acid, and regulate gene expression in various biological processes. The RAR/RXR heterodimers bind to the retinoic acid response elements (RARE) composed of tandem 5'-AGGTCA-3' sites known as DR1-DR5. The high affinity ligand for RXRs is 9-cis retinoic acid. RXRA serves as a common heterodimeric partner for a number of nuclear receptors. The RXR/RAR heterodimers bind to the retinoic acid response elements (RARE) composed of tandem 5'-AGGTCA-3' sites known as DR1-DR5. In the absence of ligand, the RXR-RAR heterodimers associate with a multiprotein complex containing transcription corepressors that induce histone acetylation, chromatin condensation and transcriptional suppression. On ligand binding, the corepressors dissociate from the receptors and associate with the coactivators leading to transcriptional activation. The RXRA/PPARA heterodimer is required for PPARA transcriptional activity on fatty acid oxidation genes such as ACOX1 and the P450 system genes.<ref>PMID:1310259</ref> <ref>PMID:10383391</ref> <ref>PMID:12032153</ref> [[http://www.uniprot.org/uniprot/MED1_MOUSE MED1_MOUSE]] Component of the Mediator complex, a coactivator involved in the regulated transcription of nearly all RNA polymerase II-dependent genes. Mediator functions as a bridge to convey information from gene-specific regulatory proteins to the basal RNA polymerase II transcription machinery. Mediator is recruited to promoters by direct interactions with regulatory proteins and serves as a scaffold for the assembly of a functional preinitiation complex with RNA polymerase II and the general transcription factors. Essential for embryogenesis, including development of the central nervous system, heart, liver and placenta and for erythropoiesis. Also required for normal transcriptional control of thyroid-stimulating hormone beta (TSHB) in the pituitary.<ref>PMID:9325263</ref> <ref>PMID:14500757</ref> <ref>PMID:10882104</ref> <ref>PMID:12037571</ref> <ref>PMID:11867769</ref> <ref>PMID:14636573</ref> <ref>PMID:15150259</ref> <ref>PMID:15340084</ref> <ref>PMID:16137621</ref> <ref>PMID:17132730</ref> [[http://www.uniprot.org/uniprot/RARB_MOUSE RARB_MOUSE]] Receptor for retinoic acid.

The RAR/RXR heterodimers bind to the retinoic acid response elements (RARE) composed of tandem 5'-AGGTCA-3' sites known as DR1-DR5. In the absence of ligand, acts mainly as an activator of gene expression due to weak binding to corepressors (By similarity). In concert with RARG, required for skeletal growth, matrix homeostasis and growth plate function. | | [https://www.uniprot.org/uniprot/RXRA_MOUSE RXRA_MOUSE] Receptor for retinoic acid.
