Target Background

Transcriptional activator. Essential for sexual differentiation and formation of the primary steroidogenic tissues. Binds to the Ad4 site found in the promoter region of steroidogenic P450 genes such as CYP11A, CYP11B and CYP21B. Also regulates the AMH/Muellerian inhibiting substance gene as well as the AHCH and STAR genes. 5'-YCAAGGYC-3' and 5'-RRAGGTCA-3' are the consensus sequences for the recognition by NR5A1. The SFPQ-NONO-NR5A1 complex binds to the CYP17 promoter and regulates basal and cAMP-dependent transcriptional activity. Binds phosphatidylcholine. Binds phospholipids with a phosphatidylinositol (PI) headgroup, in particular PI(3,4)P2 and PI(3,4,5)P3. Activated by the phosphorylation of NR5A1 by HIPK3 leading to increased steroidogenic gene expression upon cAMP signaling pathway stimulation.
Gene References into Functions
  1. The findings stress the importance of G35 residue for adrenal development. The current observation also suggests that some patients with SF1 deficiency may present with transient adrenal failure. PMID: 29151085
  2. none of the NR5A1 mutations reported to be associated with male infertility were found in our study, except one polymorphism, rs1110061. However, it was not significantly different between infertile and fertile groups. In addition, we have identified six intronic variants; but none of them was significantly associated with male infertility. PMID: 29265478
  3. In vitro functional analyses demonstrate impaired transactivation by NR5A1 mutations found in patients with 46,XY disorders of sex development. PMID: 29027717
  4. This study adds nine novel pathogenic NR5A1 variants to the pool of diagnostic variants. It highlights a greater need for understanding the complexity of SF1 function and the additional factors that contribute. PMID: 29027299
  5. rete ovarii were positive for PAX-8, weakly positive for SF-1, and negative for PAX-2 and GATA-3 PMID: 26352548
  6. SF1 was the only specific marker of uterine tumour resembling ovarian sex cord-stromal tumour PMID: 27311867
  7. this study identified a novel regulatory circuit for ovarian AMH production; specifically, through the coordinated interplay between FOXL2 and SF-1 that could control ovarian follicle development. PMID: 27414805

  9. Results identified a novel heterozygous NR5A1 mutation, c.274C>T p.(Arg92Trp), in three unrelated patients with 46,XX (ovo)testicular disorders of sex development (DSD). Transcriptomics in patient-derived lymphocytes showed upregulation of MAMLD1, a direct NR5A1 target previously associated with 46,XY DSD. This study proposes NR5A1 as a novel gene for 46,XX (ovo)testicular DSD. PMID: 27490115

PMID: 28270555

  14. we review genetic data generated through large-scale sequencing approaches that are changing our view of how this system works, including the recently described recurrent NR5A1 p.R92W mutation associated with testis development in 46,XX children PMID: 27893151
  15. The NR5A1 p.Arg92Gln variant, which has thus far only been seen in a family with 46,XY Disorder of Sex Development, most likely contributes to the ovotesticular Disorder of Sex Development in this case. PMID: 27855412
  16. Data suggest that the first screening step diagnosis for pituitary adenoma was determined based upon immunohistochemical (IHC) scores for Pit-1, SF-1, and ACTH. PMID: 27227698

  21. these results demonstrate that ASAH1 is a novel coregulatory protein that represses SF-1 function by directly binding to the receptor on SF-1 target gene promoters and identify a key role for nuclear lipid metabolism in regulating gene transcription. PMID: 22927646
  22. SF-1 expression was inhibited by miR23a/b overexpression in eutopic endometrial stromal cells(ESCs) and upregulated by miR23a/b inhibition in normal ESCs. PMID: 23450049
