Short chain dehydrogenase/reductase family 9C, member 3
FunctionCatalyzes the conversion of cortisol to the inactive metabolite cortisone. Modulates intracellular glucocorticoid levels, thus protecting the nonselective mineralocorticoid receptor from occupation by glucocorticoids.
Tissue specificityFound in placenta, kidney, pancreas, prostate, ovary, small intestine and colon.
Involvement in diseaseDefects in HSD11B2 are the cause of apparent mineralocorticoid excess (AME) [MIM:218030]. AME is a potentially fatal disease characterized by severe juvenile low-renin hypertension, sodium retention, hypokalemia and low levels of aldosterone. It often leads to nephrocalcinosis.
Sequence similaritiesBelongs to the short-chain dehydrogenases/reductases (SDR) family.
