The name mineralocorticoid derives from early observations that these hormones were involved in the retention of sodium, a mineral.The primary endogenous mineralocorticoid is aldosterone, although a number of other endogenous hormones (including progesterone [1] and deoxycorticosterone) have mineralocorticoid function.
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 affinity for mineralocorticoids and glucocorticoids.
Adrenocortical hormones are divided into three classes by function: mineralocorticoids, glucocorticoids, and androgens. Mineralocorticoid hormones are synthesized in the outermost layer of the adrenal cortex known as the zona glomerulosa. [2] Their function is to regulate the concentration of electrolytes circulating in the blood. [1]
It functions to increase blood sugar through gluconeogenesis, suppress the immune system, and aid in the metabolism of calories. [3] It also decreases bone formation. [4] These stated functions are carried out by cortisol binding to glucocorticoid or mineralocorticoid receptors inside a cell, which then bind to DNA to affect gene expression. [1 ...
Membrane mineralocorticoid receptors (mMRs) or membrane aldosterone receptors are a group of receptors which bind and are activated by mineralocorticoids such as aldosterone. [ 1 ] [ 2 ] Unlike the classical nuclear mineralocorticoid receptor (MR), which mediates its effects via genomic mechanisms, mMRs are cell surface receptors which rapidly ...
Mutations in this gene cause the syndrome of apparent mineralocorticoid excess and hypertension. [8] Since the main functions of HSD-11βs are for the regulation of glucocorticoids, the two isozymes are linked to various overstimulation or depletion of glucocorticosteroids that result in chemical imbalances in the human body.

Corticosterone has only weak glucocorticoid and mineralocorticoid potencies in humans and is important mainly as an intermediate in the steroidogenic pathway from pregnenolone to aldosterone. Corticosterone is converted to aldosterone by aldosterone synthase, found only in the mitochondria of glomerulosa cells.
