More detailed introduction
Retinoic acid receptor-related orphan receptors (ROR, nomenclature as agreed by the NC-IUPHAR Subcommittee on Nuclear Hormone Receptors [1]) have yet to be assigned a definitive endogenous ligand, although RORα may be synthesized with a ‘captured’ agonist such as cholesterol [5-6].

Tretinoin shows selectivity for RORβ within the ROR family [8]. RORα has been suggested to be a nuclear receptor responding to melatonin [10].
