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. Specifically binds 9-cis retinoic acid (9C-RA). Homodimer. Heterodimer with a RAR molecule. Binds DNA preferentially as a RAR/RXR heterodimer. Expressed in a variety of tumor cell lines. Belongs to the nuclear hormone receptor family. NR2 subfamily. Note: This description may include information from UniProtKB.
