DNA Binding Comments
DAX1 strongly differs in its structural organization from other NRs. More specifically, it lacks the conventional DNA Binding Domain of other NRs. It was reported that DAX1 binds to DNA hairpin structure with no strong sequence specificity. Interestingly it was found recently that DAX1 is an RNA binding protein associated with polyribosomes that is shuttling between the cytoplasm and the nucleus. The N-terminal repeats as well as the LBD are directly implicated in the RNA recognition.

NR0B1 Human Repressed NR0B1(DAX-1) is able to regulate its own expression by interacting with DNA hairpins present in its promoter. this has also been demonstrated in both the mouse and rat 22
STAR Human Repressed DAX1 interacts with DNA hairpin present in the StAR gene promoter and inhibit StAR expression. This inhibitory effect prevents steroid production as StAR is an essential protein for the transfer of cholesterol to the inner mitochondrial membrane, which is an essential step in steroid biosynthesis. 22

Tissue Distribution Comments
This pattern is reminiscent to the one of SF-1 and is consistent with a function of DAX1 in sex determination as well as in the control of the hypothalamus-pituitary-adrenal axis. In mice, DAX1 expression is first detected in the gonadal urogenital ridge at E10.5 and in the adrenal primordium at E12.5. In the pituitary the expression start at E14.5 whereas in the diencephalon it starts at E11.5. The first sexually divergent expression of DAX1 is seen in the gonad. In both case DAX1 expression is high at E12 but in the male (and not in the female) a rapid decline of expression follows. Similar findings have been observed in another mammal suggesting that this expression pattern is conserved. Similar patterns are seen in the mouse.

Gene Expression and Pathophysiology Comments
Since it was demonstrated as the gene responsible for the dosage sensitive sex reversal, which occurred when the DSS locus of chromosome Xp21 is duplicated, DAX1 has been used in transgenic experiments in order to test the effect of modification of the gene dosage. It was shown that XY mices carrying extra copies of mouse DAX1 as a transgene show delayed testis development when the gene is expressed at high levels but do not normally show sex reversal except when the transgene was introduced in mice strains carrying weak Sry alleles. This has confirmed the notion that DAX1 was responsible for the DSS syndrome.In order to examined the function of DAX1 in both males and females a strain of mice carrying inactivated DAX1 alleles were generated. Strikingly, although DAX1 was first postulated to function in ovarian determination, the female mices do not exhibit abnormalities of ovarian development or fertility. In contrast, in males lack of DAX1 causes progressive degeneration of the testicular germinal epithelium suggesting that DAX1 is essential for spermatogenesis. In addition these animals exhibit abnormalities in gonadotropin and testosterone production, further stressing the role of DAX1 in steroidogenesis and hypothalamus-pituitary-adrenal axis regulation.
Biologically Significant Variants Click here for help
Type:  Splice variant
Species:  Human
Description:  DAX-1 alpha. This shorter isoform of DAX-1 lacks the last 70 aa of the previously described DAX-1 protein. It is abundantly expressed in the adrenal gland, brain, kidney, ovary, and testis. DAX-1alpha can bind to steroidogenic factor 1 and to DNA but is unable to repress steroidogenic factor 1-mediated transactivation. This isoform may act as an antagonist of DAX-1.
