The estrogen receptor (ER) is a ligand-activated transcription factor composed of several domains important for hormone binding, DNA binding, and activation of transcription. Careers. cancer metastasis. Estrogen receptors (ER and ER ) are ligand-activated nuclear receptors that mediate the action of estrogens. ESTROGEN RECEPTOR TYPES a AND b STRUCTURE AND FUNCTIONAL DOMAINS ERaand ERbbelong to the steroid/thyroid hormone superfamily of nuclear receptors, members of which share a common structural architecture (99, 118, 123, 166, 218, 363). Estrogen receptors, as other members of the NHR family, are modular proteins in that distinct structural region of the receptors that display unique functional features. 12, 13 Both ERα and ERβ are encoded by two distinct genes and are expressed in the same and different tissues at varying levels. The estrogen receptor, and other nuclear receptors, are composed of several parts connected into one long chain. The structures of two of these parts are available in the PDB. by the ligand Estradiol to bind specific genes in order to regulate have hydrophobic amino acid residues that mediate the interaction between All source code for this website is freely available on, “Multidomain The estrogen receptors are members of the nuclear receptor superfamily, and share a domain structure, which is depicted schematically. The steroid hormones and their receptors are involved in the regulation of eukaryotic gene expression and affect cellular proliferation and differentiation in target tissues. 1995 Jul;9(7):814-25. doi: 10.1210/mend.9.7.7476965. Users can perform simple and advanced searches based on annotations relating to sequence, structure and function. Estrogen receptors α and β, encoded by Esr1 and Esr2, respectively, are expressed in many organs, including the hypothalamus, anterior pituitary, mammary gland, uterus, and ovary. These receptors activate transcription by similar mechanism(s), although the overall amino acid sequence identity is only 47%. 23. The translated receptors show less variability.

As a member of the wwPDB, the RCSB PDB curates and annotates PDB data according to agreed upon standards. Due to their role in cell proliferation, estrogen receptors can also increase the risk of breast cancer and uterine cancer. Successive replacements of the p-F substituent of 27 by an aminoethoxy side chain and of the 1-H of the tetrahydroisoquinoline core by a 1-Me group provided analogues 19 and 20. Accessibility Estrogen Receptor Structures & Functions Estrogen receptor structure-function is a vast topic and the subject of very active current research. certain cancers and may be key to understanding metastasis and in If cells in the breasts or uterine lining have begun to mutate due to environmental or genetic causes, the estrogen receptor can cause the mutated cells to proliferate. Limited studies queried the EDC mechanisms, focusing on limited chemicals or a set of structurally similar compounds. Since estrogen is a steroidal hormone, it can pass through the phospholipid membranes of the cell, and receptors therefore do not need to be membrane-bound in order to bind with estrogen.

Action of "pure" antiestrogens in inhibiting estrogen receptor action. The sequence similarities of human ERα, mouse ERα, rat ERα, dog ERα, and cat ERα are above 90%, but structures of ERα may different among species. Because it is likely that the pure antiestrogens bind to a similar region of the receptor as that of estradiol, we propose that they inhibit receptor dimerization by means of their 7 alpha alkyl-amide extension. J Steroid Biochem … Ligand-dependent activation of transcription by nuclear receptors (NRs) is mediated by interactions with coactivators. Distinct hydrophobic and charged residues are essential for hormone-dependent transcriptional activation, and these appear to be conserved by other members of the nuclear receptor family. developed by the Yang lab .
