RXR makes a heterodimer with subfamily 1 nuclear receptors including 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)[1]. For additional details on RXR-α see RA Mediated T-reg Differentiation. There are 3 classes of RXR: α, β and γ. RXRα plays a pivotal role in liver metabolism[2]. RXRγ mediates the anti proliferative effects of retinoid acid. Relevance RXRγ is involved in working memory and despair behavior[3].
