RARB (Retinoic acid receptor beta)

FEATURES

FAMILY

DESCRIPTION

Also known as RARB_HUMAN, RARB, HAP, NR1B2. 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 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 or presence of hormone ligand, acts mainly as an activator of gene expression due to weak binding to corepressors (PubMed:12554770). The RXRA/RARB heterodimer can act as a repressor on the DR1 element and as an activator on the DR5 element (PubMed:29021580). In concert with RARG, required for skeletal growth, matrix homeostasis and growth plate function (By similarity). Homodimer (By similarity). Heterodimer; with a RXR molecule (By similarity). Binds DNA preferentially as a RAR/RXR heterodimer (By similarity). Heterodimerizes (via NR LBD) with RXRA (PubMed:29021580). Interacts weakly with NCOR2 (PubMed:12554770).
