Adrenal and Gonad Steroidogenic Factor 1 Expression

The key events of steroidogenic tissues development in mice are shown. Molecular players in male sex (SRY, SOX9, SF-1, Dax-1) and female sex determination (Wnt4, Dax-1) are shown. Dax-1 function in sex determination is still unclear.

Steroidogenic factor 1 (SF-1) levels of expression are schematically presented below the time scale.

Abbreviations

• E - embryonic day
• dpc - days post coïtum
• dpp - days post partum
• dpo - days post ovulation

Steroidogenic Factor 1

• 53 kDa protein called Ad4BP (Adrenal 4 Binding Protein) or SF-1 (Steroidogenic Factor 1)
• classical DNA-binding domain (DBD) characterized by two Cys2-Cys2 zinc fingers in the N-terminal region
• SF-1 binds DNA as a monomer
• high homology with the drosophila Ftz-F1 transcription factor that controls fushi tarazu homeotic gene expression
