The crystal structure of the rat aα thyroid hormone receptor ligand-binding domain bound with a thyroid hormone agonist reveals that ligand is completely buried within the domain as part of the hydrophobic core. In addition, the carboxy-terminal activation domain forms an amphi-pathic helix, with its hydrophobic face constituting part of the hormone binding cavity. These observations suggest a structural role for ligand, in establishing the active conformation of the receptor, that is likely to… 

Structural Evidence for Ligand Specificity in the Binding Domain of the Human Androgen Receptor

The crystal structures of the human androgen receptor (hAR) and human progesterone receptor ligand-binding domains in complex with the same ligand metribolone (R1881) have been determined and the change of two residues in the ligands-binding pocket between the hAR and hAR is most likely the source for the specificity of R1881.

Hormone-dependent coactivator binding to a hydrophobic cleft on nuclear receptors.

Scanning surface mutagenesis on the human thyroid hormone receptor was performed to define the site that binds the coactivators, glucocorticoid receptor-interacting protein 1 (GRIP1) and steroid receptor coactivator 1 (SRC-1).

Identification of a new hormone-binding site on the surface of thyroid hormone receptor.

A new x-ray crystallographic structure of TR-LBD is reported that shows a second binding site for T3 and T4 located between H9, H10, and H11 of the TRα LBD surface, which could be useful as a new target site for drug design and could modulate selectively TR functions.

Homology modelling of the ligand-binding domain of glucocorticoid receptor: binding site interactions with cortisol and corticosterone.

The difference accessible surface area study revealed the steroid-binding region of mGR LBD, and the three-dimensional model reveals two polar sites located at the extremities of the elongated hydrophobic ligand-binding pocket.

Crystallographic comparison of the estrogen and progesterone receptor's ligand binding domains.

A peculiar crystal packing event displaces helix 12 in the hERalphaLBD reported here, suggesting a higher degree of dynamic variability than expected for this critical substructure.



Crystal structure of the ligand-binding domain of the human nuclear receptor RXR-α

The crystal structure of the human retinoid-X receptor RXR-α ligand-binding domain reveals a previously undiscovered fold of an antiparallel α-helical sandwich, packed as dimeric units. Two helices

Interactions among a subfamily of nuclear hormone receptors: the regulatory zipper model.

This "regulatory zipper model" may explain the mechanism by which ligand activates nuclear hormone receptors and suggest a novel model that structurally and functionally links these events.

Preliminary crystallographic studies of the ligand-binding domain of the thyroid hormone receptor complexed with triiodothyronine.

A truncated, recombinant form of the thyroid hormone receptor, including the hormone binding domain, has been co-crystallized with the hormone T3 and high resolution, high-quality data are obtained using synchrotron radiation in conjunction with cryocrystallography.

Identification of a conserved region required for hormone dependent transcriptional activation by steroid hormone receptors.

It is proposed that the conserved region in the C‐terminus of the hormone binding domain between residues 538 and 552 in the mouse oestrogen receptor may be essential for ligand dependent transcriptional activation by other members of the nuclear receptor family.

Protein–DNA and protein–hormone interactions in prealbumin: a model of the thyroid hormone nuclear receptor?

High resolution X-ray analysis of the hormone-binding protein pre albumin has shown that it has a structural complementarity to double-helical DNA, suggesting prealbumin as a model for the thyroid hormone nuclear receptor, providing a number of detailed predictions of its properties.

The tau 4 activation domain of the thyroid hormone receptor is required for release of a putative corepressor(s) necessary for transcriptional silencing.

This study has identified and characterized several functional domains within the ligand binding domain of the human thyroid hormone receptor (TR beta) conferring transactivation and proposed a general model in which the role of hormone is to induce a conformational change in the receptor that subsequently affects the action of tau 4, leading to both relief of silencing and transcriptional activation.

An essential role of domain D in the hormone-binding activity of human beta 1 thyroid hormone nuclear receptor.

Analysis of the T3-binding affinity and analog specificity of the purified truncated hTR beta 1 indicated that domain E alone did not have T2-binding activity, and it was concluded that the E domain alone was not sufficient to bind T3.

Interaction of thyroid-hormone receptor with a conserved transcriptional mediator

It is shown that Tripl can functionally substitute for Sugl in yeast, and that both proteins interact in vitro with the thyroid-hormone receptor, and with the transcriptional activation domains of yeast GAL4 and of herpes virus VP16.
