    basic FUNCTION
  • having ligand-dependent nuclear receptor activity, and involved in signal transduction
  • plays a crucial role in cone development by directly regulating multiple cone genes
  • pluripotent molecular player in constitutive and adaptive astrocyte physiology, exerting a bi-directional regulation of IL6 in resting and reactive astrocytes
  • cholesterol signalling through increased RORA expression stimulates chondrocyte hypertrophy and partially mediates responses of cartilage to actin dynamics
  • play a critical role in responses to cellular stress
  • contributes to the basal expression of FGF21
  • involved in regulating the Akt2-AMPK signaling pathways in the context of lipid homeostasis in skeletal muscle
  • operates at the nexus of pathways controlling the association between lipid homeostasis (lipogenesis, and fatty acid oxidation), Akt2 signaling (glucose tolerance and uptake) and AMPK signaling
  • RORA is a key molecular player in hypoxia, protecting neurons through its dual action in neurons and astrocytes
  • role of RORA in diverse pathological processes including oxidative stress-induced apoptosis and cerebral hypoxia
  • plays an important role in regulation of the circadian rhythm and metabolism
  • is a retinoid-related orphan nuclear receptor that regulates inflammation, lipid metabolism, and cellular differentiation of several non-epithelial tissues
  • RORA is a transcriptional activator of insulin, suggesting novel therapeutic opportunities for management of the diabetes
  • RORA and NR1D1 coordinately regulate the expression of the positive arm of the circadian rhythm feedback loop (
  • is a potent tumor suppressor that reduces cell proliferation and inhibits tumor growth
  • nuclear melatonin receptor RORA is a novel endogenous protective receptor against MI/R injury and an important mediator of melatonin-exerted cardioprotection
  • plays important roles in lipid, glucose metabolism, as well as the inflammatory response
  • RORA-induced ER stress response potentially contributes to the adipose tissue inflammation that can be mitigated by treatment with chemical chaperones
  • is an important regulator of various biological processes, including cerebellum development, circadian rhythm and cancer
  • has a pivotal role in the regulation of hepatic lipid homeostasis

  • interacting with EP300 and MYOD1 in myogenesis
  • interacting with NR1D1
  • target for hypoxia-inducible factor 1(HIF1A, HIF1B)

  • cholesterol sulfate induces expression of the skin barrier protein filaggrin in normal human epidermal keratinocytes through induction of RORA
  • pro-differentiation function of RORA is mediated at least in part by FOXN1, a well-known pro-differentiation transcription factor that we establish as a novel direct target of RORA in keratinocytes
