(C) Thyroid hormones are carried through the bloodstream by TBG. (D and E) In the absence of thyroid hormone, thyroid hormone receptors (TR) bind to TREs as dimers (here, represented as a homodimer), which can also bind to a corepressor (CoR). (F and G) In the presence ...

The thyroid hormones are important regulators of growth, development and metabolism. The actions of the thyroid hormones (thyroxine, T4 and triiodothyronine, T3) are initiated by binding to nuclear receptors (TRs), the cellular counterparts of the retroviral v-erbA oncogene, which act as ligand-dep...
The important physiological actions of the thyroid hormones are mediated by binding to nuclear thyroid hormone receptors (TRs), encoded by two genes TRalpha and TRbeta. These receptors act as hormone-dependent transcription factors by binding to DNA motifs located in the regulatory regions of target...
[Vitamins & Hormones] Nuclear Receptor Coregulators Volume 68 || Thyroid Hormone Receptor Subtypes and Their Interaction with Steroid Receptor Coactivators Ligand-dependent nuclear hormone receptor (NR) signaling requires direct interaction between NR and the steroid receptor coactivators (SRC). Herein we...
In previous studies of nuclear extracts containing solubilized receptors for thyroid hormones, triiodothyronine (T3) but not thyroxine (T4) binding activity was lost, even though in the starting material T3 and T4 appeared to bind to the same proteins. In the current studies this paradoxical loss ...
Thyroid hormones are hormones produced by the thyroid gland that have roles in metabolism. They are small molecules based on the amino acid tyrosine. The major thyroid hormones are triiodothyronine (T3) and thyroxine (T4), which can be processed by decarboxylation and deiodination by deiodinases, ...
TRs contain functional modular domains involved in ligand and DNA binding, homo- and hetero-dimerization with other receptors, and interaction with other transcription factors or co-factors. Binding of a ligand triggers conformational changes in TRs which, in turn, stimulate release of co- repressor...
SEPTEMBER 3, 2010 TR and LXR Regulate ChREBP in a Tissue-selective Manner Thyroid hormones (TH) up-regulate lipogenesis in liver, but their roles in WAT are controversial (9 –11). Their actions are mediated by the TR and TR nuclear receptors, which act as transcription factors by binding...
The TH receptor alpha, the monocarboxylate transporter 8 and the type 3 deiodinase appear to be major contributors to the timely regulation of TH action in the developing testis. View article Thyroid Hormone Arturo Hernandez, in Vitamins and Hormones, 2018 3.2 Thyroid Hormone Receptors: Role of ...
