Specific binding of human corticosteroid-binding globulin to cell membranes.
Specific binding sites for corticosteroid-binding globulin were detected on membranes prepared from human prostates. The binding sites are typical of membrane receptors: they are saturable and specific and have high affinity. There was little specific binding at 4 degrees C and 23 degrees C. Maximal specific binding was obtained at 37 degrees C. Scatchard analysis revealed the presence of a sin...
متن کاملPhotoaffinity labeling in target- and binding-site identification.
Photoaffinity labeling (PAL) using a chemical probe to covalently bind its target in response to activation by light has become a frequently used tool in drug discovery for identifying new drug targets and molecular interactions, and for probing the location and structure of binding sites. Methods to identify the specific target proteins of hit molecules from phenotypic screens are highly valua...
متن کاملN-glycans modulate the function of human corticosteroid-binding globulin.
Human corticosteroid-binding globulin (CBG), a heavily glycosylated protein containing six N-linked glycosylation sites, transports cortisol and other corticosteroids in blood circulation. Here, we investigate the biological importance of the N-glycans of CBG derived from human serum by performing a structural and functional characterization of CBG N-glycosylation. Liquid chromatography-tandem ...
متن کاملExpression of corticosteroid-binding globulin CBG in the human heart.
Glucocorticoids are known to be involved in myocardial regeneration and destruction. Cardiomyocytes are mostly devoid of nuclear glucocorticoid receptors (GRs) and it is generally assumed that effects of adrenal steroids in heart are mediated through the mineralocorticoid receptor (MR). Here we used immunocytochemistry to study localization of corticosteroid binding globulin (CBG) in semithin s...
متن کاملPhotoaffinity labeling of retinoic acid-binding proteins.
Retinoid-binding proteins are essential mediators of vitamin A function in vertebrate organisms. They solubilize and stabilize retinoids, and they direct the intercellular and intracellular trafficking, transport, and metabolic function of vitamin A compounds in vision and in growth and development. Although many soluble retinoid-binding proteins and receptors have been purified and extensively...
