The ligand-binding domain (LBD) contains a hydrophobic-binding pocket that attracts the hormone. Binding of the ligand alters the conformation of the LBD, resulting in the ligand being trapped within the hydrophobic environment. Functions attributed to the LBD include ligand binding, heat shock protein (HSP)-90 binding, transcriptional activation, and dimerization (Maeda, 2001).

There is great sequence homology with ER alpha in the DNA-binding domain but not in the ligand binding and hinge domains. Svenska synonymer; Engelska

Especially well studied is the thalidomide binding domain, CULT, which shows an invariable structure across different organisms and in complex with different ligands. Here, based on a series of crystal structures of a bacterial representative, we reveal the Researching motifs in the NR ligand binding domain is of utmost importance. As mentioned above in the ‘Introduction’, the ligand binding domain is a somewhat conserved domain. Finding motifs that have been conserved through the evolutionary process should highlight regions of critical importance in ligand binding. Binding of the ligand of either receptor can activate the complex, but binding of both ligands simultaneously is more potent. Three PPAR isotypes have been identified:α,β (also calledδ) and γ. PPARα is expressed most in brown adipose tissue and liver, then kidney, heart and skeletal muscle.

Toll-like receptors (TLRs) act as sentinels of the innate immune system, sensing a variety of ligands from lipopolysaccharide to flagellin to dsRNA through their ligand-binding domain that is composed of leucine-rich repeats (LRRs). Here we describe the three-dimensional crystal structures of human glucocorticoid receptor ligand-binding domain (GR-LBD) in complex with the antagonist RU-486 at 2.3 Å resolution and with the agonist dexamethasone ligand together with a coactivator peptide at 2.8 Å. 2015-05-29 · Cereblon, a primary target of thalidomide and its derivatives, has been characterized structurally from both bacteria and animals. Especially well studied is the thalidomide binding domain, CULT, which shows an invariable structure across different organisms and in complex with different ligands. Here, based on a series of crystal structures of a bacterial representative, we reveal the Researching motifs in the NR ligand binding domain is of utmost importance. As mentioned above in the ‘Introduction’, the ligand binding domain is a somewhat conserved domain.

Computed conformational free energies, validated by small-angle X-ray scattering experiments, show large differences in the stabilizing effects of cross-lobe interactions. Further, while some ligand-binding positions are largely invariant across domain instances—for example, the zinc-contacting positions in the Cys 2-His 2 zinc finger (C2H2-ZF) domain are required for proper domain folding and thus are highly conserved—other binding positions are not: amino acids within DNA-contacting positions in these same C2H2-ZF domains, for example, vary dramatically Many translated example sentences containing "ligand binding domain" – German-English dictionary and search engine for German translations.

The binding of the EGF ligand to the EGFR extracellular domain (EGFR-ECD) promotes its inactive-to-active conformational transition (activation) but the relevant detailed mechanism remains elusive st Ligand binding to the extracellular domain activates receptor [] tyrosine kinase activity, resulting in a multitude of effects, such as activation of other protein kinases, stimulation of phospholipase and phosphatidylinositol-3-kinase, and modulation of intracellular second messenger pathways. Prototypical NRs share a common structural organization with a variable amino-terminal (Nter) domain that contains a constitutively active activation function (AF)-1, a conserved DNA-binding domain (DBD) consisting of two zinc fingers (see ), a linker region, and a C-terminal (Cter) ligand-binding domain (LBD), also called HOLI domain. The bilobed ligand-binding domain of the GluK2 kainate receptor, a member of the ionotropic glutamate receptors (iGluRs), exhibits unusually high conformational flexibility compared with other iGluRs. Computed conformational free energies, validated by small-angle X-ray scattering experiments, show large differences in the stabilizing effects of cross-lobe interactions.
