Human Corticosteroid 11 Beta Dehydrogenase Isozyme 1, HSD11B1 ELI

11β-Hydroxysteroid dehydrogenase type 1, also known as cortisone reductase, is an NADPH-dependent enzyme highly expressed in key metabolic tissues including liver, adipose tissue, and the central nervous system.

In these tissues, HSD11B1 reduces cortisone to the active hormone cortisol that activates glucocorticoid receptors.

It belongs to the family of short-chain dehydrogenases.
