General description
Steroidogenic acute regulatory protein is located on human chromosome 8p11.2.
Immunogen
steroidogenic acute regulatory protein recombinant protein epitope signature tag (PrEST)
Application
Anti-STAR antibody produced in rabbit has been used to detect StAR in Paraffin-embedded adrenal samples using immunohistochemistry.
Biochem/physiol Actions
Steroidogenic acute regulatory protein (StAR) is essential for the transfer of cholesterol to mitochondria for adrenal and gonadal steroidogenesis. StAR gene analysis can help in the diagnosis of lipoid congenital adrenal hyperplasia (LCAH). It is also identified that activins A,B,AB downregulates StAR and thereby reduces the production of progesterone in human granulosa cells. Hypoxia mediated upregulation of StAR stimulates the synthesis of aldosterone in pulmonary artery endothelial cells which contributes to pulmonary vascular fibrosis. Activation of StAR helps in prevention of atherosclerotic cardiovascular disease.
Features and Benefits
Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.
Every Prestige Antibody is tested in the following ways:
- IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
- Protein array of 364 human recombinant protein fragments.
Linkage
Corresponding Antigen APREST76259.
Physical form
Solution in phosphate-buffered saline, pH 7.2, containing 40% glycerol and 0.02% sodium azide.
