Molecular evolution of the switch for progesterone and spironolactone from mineralocorticoid receptor agonist to antagonist [Medical Sciences]

The mineralocorticoid receptor (MR) is highly conserved across vertebrate evolution. In terrestrial vertebrates, the MR mediates sodium homeostasis by aldosterone and also acts as a receptor for cortisol. Although the MR is present in fish, they lack aldosterone. The MR binds progesterone and spironolactone as antagonists in human MR but...
