LXIII. Retinoid X receptors |journal= Pharmacol Rev |volume= 58 |issue= 4 |pages= 760–72 |year= 2006| doi = 10.1124/pr.58.4.7 |pmid= 17132853] is a type of
nuclear receptor which is activated by9-cis retinoic acid .cite journal |author=Allenby G, Bocquel MT, Saunders M, Kazmer S, Speck J, Rosenberger M, Lovey A, Kastner P, Grippo JF, Chambon P, Levin AA|title=Retinoic acid receptors and retinoid X receptors: interactions with endogenous retinoic acids |journal= Proc Natl Acad Sci U S A |volume= 90 |issue= 1 |pages= 30–4 |year= 1993| doi = 10.1073/pnas.90.1.30 |pmid= 8380496] There are three retinoic acid receptors (RXR), RXR-alpha, RXR-beta, and RXR-gamma encoded by the gene|RXRA, gene|RXRB, gene|RXRG genes respectively.RXR heterodimerizes with nuclear receptors including CAR, FXR, LXR, PPAR, PXR, RAR, TR, and VDR.
As with other type II nuclear receptors, the RXR heterodimer in the absence of ligand is bound to hormone response elements complexed with corepressor protein. Binding of agonist
ligand s to RXR results in dissociation of corepressor and recruitment of coactivator protein which in turn promotes transcription of the downstream targetgene intomRNA and eventuallyprotein .ee also
