The RARA gene encodes one of the three main receptor subclasses for retinoic acid. Retinoic acid receptors bind as heterodimers to their target DNA when bound to their ligand (retinoic acid) and regulate gene expression in various biological processes including hematopoiesis. The RXR/RAR heterodimers bind to the DNA retinoic acid response elements (RARE). In the absence of ligand, the RXR-RAR heterodimers associate with a multiprotein complex containing transcription corepressors that induce histone acetylation, chromatin condensation and transcriptional suppression. Upon ligand binding, the corepressors dissociate from the receptors and associate with the coactivators leading to transcriptional activation of target genes ([https://www.uniprot.org/uniprot/P10276#function adapted from Uniprot description]). | The RARA gene encodes one of the three main receptor subclasses for retinoic acid.
