Overview
NR1D1 a widely expressed member of the orphan nuclear receptor family of proteins. Expressed at relatively high levels in adipose tissue, skeletal muscle, brain and liver, and regulates cellular proliferation and differentiation. Expression increases during differentiation in adipocytes and its ectopic expression in 3T3-L1 cells potentiates adipocyte differentiation. A metabolic regulator whose expression is increased in HER2-positive breast cancer cells. Regulates malate dehydrogenase 1 (MDH1) and malic enzyme 1 (ME1), enzymes that link glycolysis and fatty acid synthesis. May contribute to the abnormal cellular energy metabolism observed in HER2-positive breast cancers. Its expression oscillates with circadian rhythm in liver cells, regulating the expression of BMAL1, ApoA1 and ApoC3, all key regulators of circadian rhythm. Represses the basal activity of the mouse Bmal1 gene promoter. Phosphorylation by GSK3b at S55/59 stabilizes NRD1 protein levels. Regulates inflammation by targeting the NF-??B responsive genes IL-6 and COX-2. NR1D1 lacks the activation function 2 domain required for ligand-dependent activation of transcription by other members of the nuclear receptor family; thus it behaves as a constitutive repressor protein, recruiting the nuclear receptor co-repressor N-CoR1/HDAC3 complex to target genes to repress transcription.
