RXRG, or Retinoid X Receptor Gamma, is a member of the RXR subfamily within the nuclear receptor superfamily, which also includes RXRA and RXRB, and functions as a ligand-dependent transcription factor that regulates gene expression primarily through the binding of 9-cis retinoic acid. Highly expressed in the central nervous system, skeletal muscle, and adipose tissue, RXRG plays a pivotal role in retinoic acid signaling, lipid metabolism, cell differentiation, and neurodevelopment by forming heterodimers with other nuclear receptors such as RARs, PPARs, and LXRs. These receptor complexes bind to specific DNA sequences, including direct repeat 1 (DR1) elements, in the promoter regions of target genes to modulate the transcription of downstream effectors like the metabolic enzyme CYP26A1 and the neurodevelopmental factor BDNF. Disruptions in RXRG function, whether through loss-of-function mutations that impair dimerization or overexpression that hyperactivates retinoic acid signaling, can lead to pathological outcomes ranging from metabolic disorders such as diabetes and lipid dysregulation to neurological conditions including schizophrenia, autism spectrum disorder, and abnormal cellular differentiation associated with tumorigenesis, underscoring the critical balance required in RXRG-mediated transcriptional control for maintaining homeostasis in development and metabolic processes.
