Functioni

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. 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 (By similarity). The RXRA/PPARA heterodimer is required for PPARA transcriptional activity on fatty acid oxidation genes such as ACOX1 and the P450 system genes.By similarity1 Publication

Post-translational modificationi

Phosphorylated on serine and threonine residues mainly in the N-terminal modulating domain. Constiutively phosphorylated on Ser-22 in the presence or absence of ligand. Under stress conditions, hyperphosphorylated by activated JNK on Ser-61, Ser-75, Thr-87 and Ser-265. Phosphorylated on Ser-28, in vitro, by PKA. This phosphorylation is required for repression of cAMP-mediated transcriptional activity of RARA (By similarity).By similarity
Sumoylation negatively regulates transcriptional activity. Desumoylated specifically by SENP6 (By similarity).By similarity
