	intracellular,cytoplasm,cytosolic,microsome

basic FUNCTION	hydroxysteroid dehydrogenase 11-beta 1, NADP dependent
	regulates glucocorticoid action at the pre-receptor stage by converting cortisone to cortisol
	playing a role in cell-to-cell signaling
	regenerates active cortisol from inactive cortisone
	bi-directional, vascular 11beta-HSD1 favors reactivation (reductase) over the deactivation (dehydrogenase) reaction, impairing Gc (glucocorticoids) deactivation (correlated with lower vascular resistance)
	implicated in the pathogenesis of central obesity and metabolic syndrome
