Retinoic acid receptor alpha (RAR-α), also known as NR1B1 (nuclear receptor subfamily 1, group B, member 1) is a nuclear receptor that in humans is encoded by the RARA gene.[5][6]

NR1B1 is a gene with a protein product and has a chromosomal location of 17q21.2. RARA codes for the nuclear hormone receptor Retinoic Acid Receptor, Alpha subtype, and are themselves transcription factors. There are another 2 subtypes of RARs, Beta subtype, and Gamma subtype.[7][8]

Function[]

Retinoid signaling is transduced by 2 families of nuclear receptors, retinoic acid receptor (RAR) and retinoid X receptor (RXR), which form RXR/RAR heterodimers. In the absence of ligand, DNA-bound RXR/RARA represses transcription by recruiting the corepressors NCOR1, SMRT (NCOR2), and histone deacetylase. When ligand binds to the complex, it induces a conformational change allowing the recruitment of coactivators, histone acetyltransferases, and the basic transcription machinery.[9]

Retinoic Acid Receptor Alpha, the protein, interacts with retinoic acid, a derivative of Vitamin A, which plays an important role in cell growth, differentiation, and the formation of organs in embryonic development.[8][10]

Once Retinoic Acid binds to the RAR, they initiate transcription and allow for their respective gene to be expressed. [10] 

Clinical significance[]

RA signaling has been correlated with several signaling pathways in early embryonic development. First, it participates in the formation of the , which establishes symmetry in the offspring. RA also influences neural differentiation by regulating the expression of pro-neural induction factor Neurogenin 2 (Neurog2). RA affects cardiogenesis, as it plays a role specifically in the formation of the atrial chambers of the heart. RA also plays a role in the development of the pancreas, kidneys, lungs, and extremities.  [10]

Translocations that always involve rearrangement of the RARA gene are a cardinal feature of acute promyelocytic leukemia (APL; MIM 612376). The most frequent translocation is t(15,17)(q21;q22), which fuses the RARA gene with the PML gene.[11]

Interactions[]

Retinoic acid receptor alpha has been shown to interact with:

Genetic Studies[]

Knock-out mice studies showed that a deletion in one of the copies of the RARA gene did not create any observable defect, while deletion of both copies shoes symptoms similar to that of Vitamin A deficiency. This proved that all 3 subtypes of RARs work redundantly.
