DESCRIPTION

Also known as STF1_HUMAN, NR5A1, AD4BP, FTZF1, SF1. Transcriptional activator. Essential for sexual differentiation and formation of the primary steroidogenic tissues (PubMed:27378692). 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 (PubMed:27378692). The SFPQ-NONO-NR5A1 complex binds to the CYP17 promoter and regulates basal and cAMP-dependent transcriptional activity. Binds phosphatidylcholine (By similarity). 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. Binds DNA as a monomer. Interacts with NR0B2 and PPARGC1A (By similarity). Part of a complex consisting of SFPQ, NONO and NR5A1. Interacts with NCOA2. Interacts with DGKQ and CDK7. Binds to and activated by HIPK3.
