Nurr1/NGFI-B beta/NR4A2: Proteins and Enzymes

Nurr1 belongs to the nerve growth factor-induced clone B subfamily of nuclear receptor superfamily and is designated NR4A2 in the Unified Nomenclature System for NRs. Nurr1 can function as a ligand-independent transcription factor. Nurr1 also heterodimerizes with retinoid X receptors (RXRs) to function as ligand-regulated transcription factor. Nurr 1 is important for specification of dopaminergic neurons that degenerate in Parkinsons disease. Human and mouse Nurr1 share 99% amino acid sequence homology.
