The mineralocorticoid receptor (or MR, MLR, MCR), also known as the aldosterone receptor or nuclear receptor subfamily 3, group C, member 2, (NR3C2) is a protein that in humans is encoded by the NR3C2 gene that is located on chromosome 4q31.1-31.2.[5]
MR is a receptor with equal
Function
MR is expressed in many tissues, such as the
The receptor is activated by mineralocorticoids such as aldosterone and its precursor deoxycorticosterone as well as glucocorticoids like cortisol. In intact animals, the mineralocorticoid receptor is "protected" from glucocorticoids by co-localization of an enzyme, corticosteroid 11-beta-dehydrogenase isozyme 2 (a.k.a. 11β-hydroxysteroid dehydrogenase 2; 11β-HSD2), that converts cortisol to inactive cortisone.[6]
Activation of the mineralocorticoid receptor, upon the binding of its ligand aldosterone, results in its
An activating mutation in the NR3C2 gene (S810L) results in constitutive activity of the mineralocorticoid receptor, leading to severe early-onset hypertension that is exacerbated by pregnancy. In a family known to harbor the S810L mutation, 3 individuals carrying the mutation died of chronic heart failure before age 50.[8] Additional studies have shown that this activated version of MR can positively respond to ligands that are traditionally antagonists, such as endogenous hormones like progesterone, and the diuretic drugs spironolactone and eplerenone.[8]
