Function

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. In concert with RARG, required for skeletal growth, matrix homeostasis and growth plate function. {ECO:0000269PubMed:12554770}.

Disease Associations

Microphthalmia, syndromic, 12 (MCOPS12) [MIM:615524]: A form of microphthalmia, a disorder of eye formation, ranging from small size of a single eye to complete bilateral absence of ocular tissues (anophthalmia). In many cases, microphthalmia/anophthalmia occurs in association with syndromes that include non-ocular abnormalities. MCOPS12 patients manifest variable features, including diaphragmatic hernia, pulmonary hypoplasia, and cardiac abnormalities. {ECO:0000269PubMed:24075189}. Note=The disease is caused by mutations affecting the gene represented in this entry.
