1 11 beta-hydroxysteroid dehydrogenase-2 is a high affinity corticosterone-binding protein. Corticosterone hydroxysteroid 11-beta dehydrogenase 2 Homo sapiens
2 Based on similarities in steroid specificity and kinetic parameters, we hypothesized that these corticosterone binding sites belong to the type 2 isoform of 11 beta-hydroxysteroid dehydrogenase (11 beta-HSD2). Corticosterone hydroxysteroid 11-beta dehydrogenase 2 Homo sapiens
3 Based on similarities in steroid specificity and kinetic parameters, we hypothesized that these corticosterone binding sites belong to the type 2 isoform of 11 beta-hydroxysteroid dehydrogenase (11 beta-HSD2). Corticosterone hydroxysteroid 11-beta dehydrogenase 2 Homo sapiens
4 The goal of this study was to express the recombinant rabbit 11 beta-HSD2 in mammalian cells and test if such cells acquire both NAD-dependent 11 beta-HSD2 activity as well as high affinity corticosterone binding sites. Corticosterone hydroxysteroid 11-beta dehydrogenase 2 Homo sapiens
5 The steroid specificity of the binding sites, as determined by competing [3H]corticosterone with unlabeled steroids, is identical to that of 11 beta-HSD2: corticosterone >> 11-hydroxyprogesterone > carbenoxolone > 11 dehydrocorticosterone > cortisol > progesterone approximately DOC >>> DEX > RU 28362 - aldosterone. Corticosterone hydroxysteroid 11-beta dehydrogenase 2 Homo sapiens
6 These results strongly suggest that the previously described high affinity corticosterone binding sites are 11 beta-HSD2. Corticosterone hydroxysteroid 11-beta dehydrogenase 2 Homo sapiens
