There are two main types of estrogen receptor (ER): estrogen receptor alpha (ERα), and estrogen receptor beta (ER-β), also known as NR3A2. Both are nuclear receptors activated by the sex hormone estrogen. Estrogen signaling can be selectively stimulated or inhibited, dependent on the equilibrium of these two receptor types in target organs. [4]
Estrogen receptor alpha (ERα), also known as NR3A1 (nuclear receptor subfamily 3, group A, member 1), is one of two main types of estrogen receptor, a nuclear receptor (mainly found as a chromatin-binding protein [5]) that is activated by the sex hormone estrogen. In humans, ERα is encoded by the gene ESR1 (EStrogen Receptor 1). [6] [7] [8]
Estrogen insensitivity syndrome (EIS), or estrogen resistance, is a form of congenital estrogen deficiency or hypoestrogenism [2] which is caused by a defective estrogen receptor (ER) – specifically, the estrogen receptor alpha (ERα) – that results in an inability of estrogen to mediate its biological effects in the body. [3]
There are two different forms of the estrogen receptor, usually referred to as α and β, each encoded by a separate gene (ESR1 and ESR2, respectively).Hormone-activated estrogen receptors form dimers, and, since the two forms are coexpressed in many cell types, the receptors may form ERα (αα) or ERβ (ββ) homodimers or ERαβ (αβ) heterodimers. [3]
The ERRs are orphan nuclear receptors, meaning the identity of their endogenous ligand has yet to be unambiguously determined. They are named because of sequence homology with estrogen receptors, but do not appear to bind estrogens or other tested steroid hormones. There are three human estrogen related receptors: ERRα ; ERRβ ; ERRγ

Peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC-1α) is a protein that in humans is encoded by the PPARGC1A gene. [4] PPARGC1A is also known as human accelerated region 20 . It may, therefore, have played a key role in differentiating humans from apes. [5] PGC-1α is the master regulator of mitochondrial biogenesis.
[2] [4] Although 17α-estradiol is far weaker than 17β-estradiol as an agonist of the nuclear estrogen receptors, it has been found to bind to and activate the brain-expressed ER-X with a greater potency than that of 17β-estradiol, suggesting that it may be the predominant endogenous ligand for the receptor.
