Domain

Composed of three domains: a modulating N-terminal domain, a DNA-binding domain and a C-terminal ligand-binding domain.

Function

Receptor for both mineralocorticoids (MC) such as aldosterone and glucocorticoids (GC) such as corticosterone or cortisol. Binds to mineralocorticoid response elements (MRE) and transactivates target genes. The effect of MC is to increase ion and water transport and thus raise extracellular fluid volume and blood pressure and lower potassium levels.

Involvement in disease

Pseudohypoaldosteronism 1, autosomal dominant

PHA1A

A salt wasting disease resulting from target organ unresponsiveness to mineralocorticoids. PHA1A is a mild form characterized by target organ defects confined to kidney. Patients may present with neonatal renal salt wasting with hyperkalaemic acidosis despite high aldosterone levels. These patients improve with age and usually become asymptomatic without treatment.

None

The disease is caused by variants affecting the gene represented in this entry.

Early-onset hypertension with severe exacerbation in pregnancy

EOHSEP

Inheritance is autosomal dominant. The disease is characterized by the onset of severe hypertension before the age of 20, and by suppression of aldosterone secretion.

None

The disease is caused by variants affecting the gene represented in this entry.

Post-translational modifications

Phosphorylated.

Sequence similarities

Belongs to the nuclear hormone receptor family. NR3 subfamily.

Tissue specificity

Ubiquitous. Highly expressed in distal tubules, convoluted tubules and cortical collecting duct in kidney, and in sweat glands. Detected at lower levels in cardiomyocytes, in epidermis and in colon enterocytes.

Cellular localization

  • Cytoplasm
  • Nucleus
  • Endoplasmic reticulum membrane
  • Peripheral membrane protein
  • Cytoplasmic and nuclear in the absence of ligand; nuclear after ligand-binding. When bound to HSD11B2, it is found associated with the endoplasmic reticulum membrane.
