Rabbit Anti-HSD11B2/FITC Conjugated antibody
background:
There are at least two isozymes of the corticosteroid 11-beta-dehydrogenase, a microsomal enzyme complex responsible for the interconversion of cortisol and cortisone. The type I isozyme has both 11-beta-dehydrogenase (cortisol to cortisone) and 11-oxoreductase (cortisone to cortisol) activities. The type II isozyme, encoded by this gene, has only 11-beta-dehydrogenase activity. In aldosterone-selective epithelial tissues such as the kidney, the type II isozyme catalyzes the glucocorticoid cortisol to the inactive metabolite cortisone, thus preventing illicit activation of the mineralocorticoid receptor. In tissues that do not express the mineralocorticoid receptor, such as the placenta and testis, it protects cells from the growth-inhibiting and/or pro-apoptotic effects of cortisol, particularly during embryonic development. Mutations in this gene cause the syndrome of apparent mineralocorticoid excess and hypertension. [provided by RefSeq, Feb 2010]
Function:
Catalyzes the conversion of cortisol to the inactive metabolite cortisone. Modulates intracellular glucocorticoid levels, thus protecting the nonselective mineralocorticoid receptor from occupation by glucocorticoids.
Subunit:
Interacts with ligand-free cytoplasmic NR3C2.
Subcellular Location:
Microsome. Endoplasmic reticulum.
Tissue Specificity:
Found in placenta, kidney, pancreas, prostate, ovary, small intestine and colon.
Similarity:
Belongs to the short-chain dehydrogenases/reductases (SDR) family.

[DISEASE] Defects in HSD11B2 are the cause of apparent mineralocorticoid excess (AME) [MIM:23630]. An autosomal recessive form of low-renin hypertension. It is usually diagnosed within the first years of life and is characterized by polyuria and polydipsia, failure to thrive, hypernatremia, severe hypertension with low renin and aldosterone levels, profound hypokalemia with metabolic alkalosis, and most often nephrocalcinosis.
