NR4
NR4A family orphan nuclear receptors are an important class of transcription factors for development and homeostasis of dopaminergic neurons that also inhibit expression of inflammatory genes in glial cells[1]. Nur77 (NGIF-B/NR4A1), Nurr1 (NOT/NR4A2), and NOR-1 (MINOR/NR4A3) form a family of orphan nuclear receptors with a highly conserved DNA-binding domain and COOH-terminal ligand-binding domain, but minimal homology in their NH2-terminal region[2].
