DNA Binding Comments
In the NR5A subfamily, specificity of DNA binding is dictated by the Ftz-F1 box, which is a stretch of 26 amino acids at the C terminus of the DBD.
Co-binding Partners
Name Interaction Effect Reference
DAX1 Physical, Functional Inhibition of LRH-1 dependent transactivation. 21
SHP Physical, Functional Inhibition of LRH-1 dependent transactivation. 14,21
Beta catenin Physical, Functional DNA binding and LRH-1 interacts with the armadillo repeats of beta-catenin. Beta catenin:LRH-1 complex formation enhance LRH-1 dependent transcriptional activation of the Cyclin E1 gene and beta catenin dependent activation of the Cyclin D1 gene. 2
Main Co-regulators
Name Activity Specific Ligand dependent AF-2 dependent Comments References
NCOA1 Co-activator No No Yes 28
NCOA3 Co-activator No No Yes 17
EP300 Co-activator No No Yes 27
EID1 Co-activator No No No MBF-1 interacts with the Ftz-F1 box of LRH-1 and not with the AF-2. MBF-1 does not possess any of the classical histone modifying activities such as histone acetyl- or methyl transferase activities, linked to chromatin remodeling, but interacts in vitro with the transcription factor IID complex 3
PROX1 Co-repressor No No No Prox1 interacts with both the ligand binding domain (LBD) and the DNA binding domain (DBD) of hLRH-1. Gel shift assays reveal that Prox1 impairs the binding of hLRH-1 to the promoter of human cyp7a1 gene 20,25
SNW1 Co-activator No No No NCOA62 interacts and selectively activates LRH-1 in cell transfections assays. The SNW domain is required. (personal expert communication)

Physiological Consequences of Altering Gene Expression
LRH-1 Knock-out Mice: LRH-1 -/- embryos die at E6.5–7.5, with features typical of visceral endoderm dysfunction. LRH-1 +/- adult mice are hypocholesterolemic, and express liver FTF at about 40% of the normal level. Haplo insufficiency of LRH-1 blunts intestinal tumorigenesis in the ApcMin/+ mice, a genetic model of intestinal cancer. Lrh-1+/- mice are protected against the formation of aberrant crypt foci in the colon of mice exposed to the carcinogen azoxymethane.
