Previous GeneCards Identifiers for RARA Gene
This gene represents a nuclear retinoic acid receptor. The encoded protein, retinoic acid receptor alpha, regulates transcription in a ligand-dependent manner. This gene has been implicated in regulation of development, differentiation, apoptosis, granulopoeisis, and transcription of clock genes. Translocations between this locus and several other loci have been associated with acute promyelocytic leukemia. Alternatively spliced transcript variants have been found for this locus.[provided by RefSeq, Sep 2010]
GeneCards Summary for RARA Gene
RARA (Retinoic Acid Receptor Alpha) is a Protein Coding gene. Diseases associated with RARA include Acute Promyelocytic Leukemia and Leukemia. Among its related pathways are Apoptotic Pathways in Synovial Fibroblasts and PEDF Induced Signaling. Gene Ontology (GO) annotations related to this gene include DNA binding transcription factor activity and protein heterodimerization activity. An important paralog of this gene is RARB.
UniProtKB/Swiss-Prot for RARA Gene
Receptor for retinoic acid. Retinoic acid receptors bind as heterodimers to their target response elements in response to their ligands, all-trans or 9-cis retinoic acid, and regulate gene expression in various biological processes. The RXR/RAR heterodimers bind to the retinoic acid response elements (RARE) composed of tandem 5-AGGTCA-3 sites known as DR1-DR5. 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. On ligand binding, the corepressors dissociate from the receptors and associate with the coactivators leading to transcriptional activation. RARA plays an essential role in the regulation of retinoic acid-induced germ cell development during spermatogenesis. Has a role in the survival of early spermatocytes at the beginning prophase of meiosis. In Sertoli cells, may promote the survival and development of early meiotic prophase spermatocytes. In concert with RARG, required for skeletal growth, matrix homeostasis and growth plate function (By similarity). Regulates expression of target genes in a ligand-dependent manner by recruiting chromatin complexes containing KMT2E/MLL5. Mediates retinoic acid-induced granulopoiesis.
Retinoic acid receptors (RARs) are nuclear hormone receptors of the NR1B class, which function as heterodimers with retinoid X receptors (RXRs). There are three distinct RAR subtypes: RARalpha, present in most tissue types; and RARbeta and RARgamma, with more selective expression.
