Unliganded RAR/RXR dimers bind to Retinoic Acid Response Elements (RAREs) on DNA, acting as repressors by recruiting corepressor proteins.
Binding of agonist ligands causes corepressors to dissociate and coactivator proteins to bind, promoting the transcription of target genes. Subtypes & Expression: There are three RAR subtypes ( Mechanism.rar
Retinoic acid (RA) binds to the RAR-RXR complex within the nucleus, activating it to regulate genes involved in development, differentiation, and apoptosis. Transcriptional Control: Unliganded RAR/RXR dimers bind to Retinoic Acid Response
Synthetic RAR agonists (like Tamibarotene/AM80) are being developed for treating diabetes, immune diseases, and various skin conditions. specifically neural patterning
RARs act as ligand-activated transcription factors that form heterodimers with Retinoid X Receptors (RXRs) to regulate gene expression.
RAR signaling is essential for embryonic morphogenesis, specifically neural patterning, limb development, and organogenesis.
