The nuclear receptor SF-1 (steroidogenic factor-1) is no longer an orphan.
The nuclear hormone receptor SF-1 (steroidogenic factor-1, also termed adrenal 4-binding protein or Ad4BP) is a major regulator of the development and function of the hypothalamic–pituitary–adrenal and –gonadal axes. It was initially discovered as a key transcription factor regulating the cytochrome P450 steroid hydroxylases in the gonads and the adrenal cortex (1, 2). The promoter of the genes...
متن کاملRegulation of the orphan nuclear receptor steroidogenic factor 1 by Sox proteins.
Steroidogenic factor 1 (SF-1) is an essential factor in endocrine proliferation and gene expression. Despite the fact that SF-1 expression is restricted to specialized cells within the endocrine system, the only identified regulatory factors of SF-1 are the ubiquitously expressed E-box proteins (upstream stimulatory factors 1 and 2). Sequence examination of the SF-1 proximal promoter revealed a...
متن کاملSteroidogenic factor-1 (SF-1, NR5A1) and human disease
Steroidogenic factor-1 (SF-1, Ad4BP, encoded by NR5A1) is a key regulator of adrenal and reproductive development and function. Based upon the features found in Nr5a1 null mice, initial attempts to identify SF-1 changes in humans focused on those rare individuals with primary adrenal failure, a 46,XY karyotype, complete gonadal dysgenesis and Müllerian structures. Although alterations affecting...
متن کاملAn autoregulatory loop controlling orphan nuclear receptor DAX-1 gene expression by orphan nuclear receptor ERRγ
The estrogen receptor-related receptor gamma (ERRgamma/ERR3/NR3B3) is a member of the nuclear receptor superfamily that activates transcription in the absence of ligand. However, the detailed mechanism of gene regulation by ERRgamma is not fully understood. In this study we have found that the orphan nuclear receptor ERRgamma activates the DAX-1 promoter, which, in turn, represses transactivati...
متن کاملNuclear receptor steroidogenic factor 1 directs embryonic stem cells toward the steroidogenic lineage.
The orphan nuclear receptor steroidogenic factor 1 (SF-1) is expressed in the adrenal gland and gonads and is an important regulator of the expression of cytochrome P-450 steroidogenic enzymes in cultured cells. Targeted disruption of the SF-1 gene in mice shows that it is a critical participant in the genetic program that promotes the development of urogenital mesoderm into the adrenal gland a...
