The function of NR4A2 (nuclear receptor subfamily 4 group A member 2, Ensembl gene identifier ENSG00000153234) is as follows. Transcriptional regulator which is important for the differentiation and maintenance of meso-diencephalic dopaminergic (mdDA) neurons during development (PubMed:15716272, PubMed:17184956). It is crucial for expression of a set of genes such as SLC6A3, SLC18A2, TH and DRD2 which are essential for development of mdDA neurons (By similarity). {ECO:0000250|UniProtKB:Q06219, ECO:0000269|PubMed:15716272, ECO:0000269|PubMed:17184956}.
