Retinoic acid receptor
This article is licensed under the GNU Free Documentation License. It uses material from the Wikipedia article "Retinoic_acid_receptor" .
The retinoic acid receptor (RAR) is a type of nuclear receptor [1] which is activated by both all-trans retinoic acid and 9-cis retinoic acid .[2] There are three retinoic acid receptors (RAR), RAR-alpha , RAR-beta , and RAR-gamma encoded by the RARA , RARB , RARG genes respectively. Each receptor isoform has several splice variants: two- for alpha, four- for beta and two- for gamma.
As with other type II nuclear receptors, RAR heterodimerizes with RXR and in the absence of ligand, the RAR/RXR dimer binds to hormone response elements complexed with corepressor protein. Binding of agonist ligands to RAR results in dissociation of corepressor and recruitment of coactivator protein which in turn promotes transcription of the downstream target gene into mRNA and eventually protein .
