'''Retinoid X receptor''' (RXR) is a [[Nuclear receptors|nuclear receptor]] activated by 9-''cis'' retinoic acid. RXR makes a heterodimer with subfamily 1 nuclear receptors including [[Retinoic acid receptor|retinoic acid receptor]] (RAR). In the absence of ligand, the RAR/RXR complex binds the hormone response elements complexed with corepressor protein. Upon binding of the ligand, the corepressor disassociates from the receptor and associates with the coactivator leading to transcription activation. RXR contains a DNA-binding domain (DBD) and ligand-binding domain (LBD)<ref>PMID:22020178</ref>. For additional details on RXR-α see [[RA Mediated T-reg Differentiation]]. | '''Retinoid X receptor''' (RXR) is a [[Nuclear receptors|nuclear receptor]] activated by 9-''cis'' retinoic acid.
