Steroidogenic Factor 1 (SF-1) also designated Nuclear Receptor Subfamily 5 Group A Member 1 (NR5A1), Adrenal 4 Binding Protein (AD4BP), HSF-1, is a transcription factor belongs the fushi tarazu factor-1 (FTZ-F1) subfamily of orphan nuclear receptors. It regulates multiple genes involved in the organ development and differentiation of the endocrine system. SF-1 plays an important role in fetal development of the hypothalamus, pituitary gland, gonads, and the adrenal gland. Its expression is observed in all steroidogenic tissues, including the adrenal cortex, testicular Sertoli cells, and Leydig cells, ovarian theca/interstitial cells, granulosa cells, hypothalamus, and anterior pituitary. SF1 is highly valuable IHC marker to determine the adrenocortical origin of an adrenal mass and differential diagnosis of endometrioid tumors with carcinoid of the ovary.
