Product Specific Information
Immunohistochemistry (PFA fixed):
Incubate antibody for 30 minutes at room temperature.
Staining of formalin-fixed tissues requires heating tissue sections in 10 mM Tris with 1 mM EDTA, pH 9.0, for 45 minutes at 95°C, followed by cooling at room temperature for 20 minutes.
Target Information
Steroidogenic acute regulatory protein (StAR) plays a significant role in cholesterol transport from the cytoplasmic outer membrane to the inner mitochondrial membrane.
The 37 kDa precursor is cleaved to generate an active 28 kDa protein capable of facilitating cholesterol metabolism into pregnenolone.
StAR is prevalently expressed in mitochondria of steroid-producing adrenal and gonadal tissues.
Abnormalities in StAR gene expression are implicated in autosomal Lipoid Congenital Adrenal Hyperplasia (LCAH), resulting in defects in pregnenolone and cortisol synthesis.
The mechanism of cholesterol binding to StAR has yet to be elucidated.
