an orphan nuclear receptor and immediate-early gene that regulates cellular proliferation, apoptosis, inflammation, and glucose metabolism. Induced by exercise in muscle and is a functional regulator of glucose metabolism in skeletal muscle. Its level decreases in the muscle of obese insulin-resistant men. Acts concomitantly with NURR1 in regulating the expression of delayed-early genes during liver regeneration. Binds the NGFI-B response element (NBRE) 5'-AAAAGGTCA-3'. May inhibit NF-kappa-B transactivation of IL2. A mediator of TCR-directed thymocyte apoptosis. TCR-signaling induces a FAIM/Akt/Nur77 signaling pathway that is critical for modulating apoptosis in developing thymocytes. A physiological substrate of the MEK-ERK-RSK cascade that modulates nuclear export and intracellular translocation during T cell death. Binds DNA as a monomer. Interacts with GADD45GIP1. Overexpression of Nur77 induces the expression of both p300 and HDAC1. Acetylation by p300 and HDAC1 may regulate the rapid turnover of Nur77 protein.
