The NR LBD domain binds the lipid A moiety of lipopolysaccharide (LPS) in the cytosol.
Orphan nuclear receptor. Binds the NGFI-B response element (NBRE) 5'-AAAGGTCA-3' (PubMed:18690216, PubMed:8121493, PubMed:9315652). Binds 9-cis-retinoic acid outside of its ligand-binding (NR LBD) domain (PubMed:18690216). Participates in energy homeostasis by sequestrating the kinase STK11 in the nucleus, thereby attenuating cytoplasmic AMPK activation (PubMed:22983157). Regulates the inflammatory response in macrophages by regulating metabolic adaptations during inflammation, including repressing the transcription of genes involved in the citric acid cycle (TCA) (By similarity). Inhibits NF-kappa-B signaling by binding to low-affinity NF-kappa-B binding sites, such as at the IL2 promoter (PubMed:15466594). May act concomitantly with NR4A2 in regulating the expression of delayed-early genes during liver regeneration (By similarity). Plays a role in the vascular response to injury (By similarity).
In the cytosol, upon its detection of both bacterial lipopolysaccharide (LPS) and NBRE-containing mitochondrial DNA released by GSDMD pores during pyroptosis, it promotes non-canonical NLRP3 inflammasome activation by stimulating association of NLRP3 and NEK7.
Phosphorylated at Ser-351 by RPS6KA1 and RPS6KA3 in response to mitogenic or stress stimuli.
Acetylated by p300/CBP, acetylation increases stability. Deacetylated by HDAC1.
Belongs to the nuclear hormone receptor family. NR4 subfamily.
Fetal muscle and adult liver, brain and thyroid.
