Developmental roles of the steroidogenic acute regulatory protein (StAR) as revealed by StAR knockout mice.
Steroidogenic acute regulatory protein (StAR) is essential for adrenal and gonadal steroidogenesis, stimulating the translocation of cholesterol to the inner mitochondrial membrane where steroidogenesis commences. StAR mutations in humans cause congenital lipoid adrenal hyperplasia (lipoid CAH), an autosomal recessive condition with severe deficiencies of all classes of steroid hormones. We pre...
متن کاملCholesterol binding is a prerequisite for the activity of the steroidogenic acute regulatory protein (StAR).
Steroidogenesis depends on the delivery of cholesterol from the outer to the inner mitochondrial membrane by StAR (steroidogenic acute regulatory protein). However, the mechanism by which StAR binds to cholesterol and its importance in cholesterol transport are under debate. According to our proposed molecular model, StAR possesses a hydrophobic cavity, which can accommodate one cholesterol mol...
متن کاملDiazinon interrupts ovarian steroidogenic acute regulatory (StAR) gene transcription in gonadotropin-stimulated rat model
Organophosphate pesticides are considered as endocrine disruptors that interfere with reproductive functions. The corpus luteum (CL) is a transient endocrine gland that produces progesterone, a crucial hormone for a successful beginning and maintenance of pregnancy. Steroidogenic acute regulatory protein (StAR) facilitates the rate-limiting transfer of cholesterol from the outer mitochondrial m...

متن کاملThe steroidogenic acute regulatory protein is expressed in steroidogenic cells of the day-old brain.
Although recent research has focused on the fundamental role(s) of steroids synthesized de novo in the brain on development, the mechanism by which production of these neurosteroids is regulated remains unclear. Steroid production in peripheral tissues is acutely regulated by the steroidogenic acute regulatory (StAR) protein, which mediates the rate-limiting step in steroid biosynthesis: the in...
