NR0B1

NR0B1

A gene (popularly known as DAX1) on chromosome Xp21.3 that encodes a protein containing a DNA-binding domain, which acts as a dominant-negative regulator of transcription mediated by the retinoic acid receptor. NR0B1 also acts as an anti-testis gene by antagonising SRY.
 
Molecular pathology
NR0B1 mutations cause both X-linked congenital adrenal hypoplasia and hypogonadotropic hypogonadism.

Finally, recent evidence suggests that PPAR[gamma] is able to induce apoptosis in lung cancer, although it can be inhibited by NR0B1, an orphan nuclear receptor whose knockdown reduces tumorigenic and antiapoptotic potential [75].

Nevertheless, ACBD3 takes the central place of an interaction network that composed of multiple genes involving steroid and cholesterol synthesis, including STAR, SCP2, NR0B1, acyl coenzyme-related ACBD1 and BACH, BLZF1, lipid degradation protein (AZGP1, alpha-2-glycoprotein 1, zinc-binding), and several p24 family members [54].
AHC manifests itself mainly in early infancy or in childhood and is caused by deletions or point mutations in the NR0B1 (DAX1) (dosage-sensitive sex reversal, adrenal hypoplasia critical region, on chromosome X, gene 1) gene (OMIM*300473) (Figures 1(a)-1(c)) [1].
The genes surrounding the GK gene, from telomere to centromere, are Xpter-interleukin 1 receptor accessory protein-like 1 (IL1RAPL1); nuclear receptor subfamily 0, group B, member 1 (NR0B1); GK, dystropin (DMD); and ornithine carbamoyltransferase (OTC)-cent.
NR0B1 is an orphan member of the nuclear receptor superfamily.
The deletion included part of the DMD gene, the entire NR0B1 gene, and part of the IL1RAPL1 gene (Figure 4).
DAX-1 (NR0B1), a close partner of SF-1, acts as an adaptor that recruits other factors, such as the nuclear receptor corepressors to SF-1.
