A Binding Site Domain is a region of protein that physically interacts stereospecifically, and usually at high affinity, with a specific ligand, substrate, or a specific domain of some complex target biomolecule, such as a protein, lipid, carbohydrate, or nucleic acid. Typically, but not necessarily, the interaction results in protein conformational alteration and functional modification.

Translations in context of "ligand binding domain" in English-German from Reverso Context: A gene which encodes the ligand binding domain of HNF-4. Our studies thus reveal the C-terminal repeat moiety as the ligand binding domain of TcdA as has been suggested earlier . The binding of TcdA to F9 cells was likely to be mediated by surface glycans since three saccharides, Le x (X-hapten), poly- N -acetyllactosamine (I-antigen) and Galα3Galβ4GlcNAc, which have been reported to bind to TcdA [ 38 , 39 ], are known to be expressed on F9 cells 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. 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.

https: Abstract. The androgen receptor (AR) ligand-binding domain (LBD) binds FXXLF motifs, present in the AR N-terminal domain and AR-specific cofactors, and The C‐terminal ligand‐binding domain (LBD) is multifunctional and, in addition to harbouring a ligand recognition site, contains regions for receptor dimerization Sep 23, 2009 These data show that the glutamate binding domains are surprisingly mobile in the absence of ligand, which could influence receptor activity in ing domain (DBD), and a C-terminal ligand binding domain. (LBD), which is responsible for high affinity ligand binding, dimerization, and hormone- dependent Binding assays with a soluble Notch extracellular domain fusion protein and ligand-expressing cells indicate that the NEGF12f mutation can influence Notch All NR ligand-binding domains have a similar fold, which allows for comparison of the structures of their three main functional sites: the ligand-binding pocket, the Farnesoid X Receptor, Ligand Binding Domain (FXR-LBD) is a 60.07 kDa recombinant human protein (amino acids 193-472) expressed as a GST fusion protein May 7, 2019 The understanding of conformational changes in its ligand binding domain (LBD) is valuable for both biological function studies and Jul 10, 2020 This suggests that the MIDAS is important for ligand binding but not for productive motility.

When a ligand binds to its respective receptor, the shape and/or activity of the Each RTK has an extracellular domain that contains the ligand-binding site, Jun 11, 2018 The α subunit of the integrin heterodimer especially the αI domain determines the ligand specificity for cell-ECM adhesion (reviewed in [3]).

For example, the extracellular domains of both TNF RI and TNF RII contain three cysteine-rich domains (CRD1, CRD2 and CRD3) characteristic of TNF R superfamily members and a less conserved, fourth cysteine-rich domain that is membrane-proximal. 5 CRD2 and CRD3 form the ligand binding pocket for TNF-alpha. 5 Previous studies have shown that TNF R superfamily signaling may be induced upon ligand

The potential H bonding residues (orange, blue and red) that are adjacent to this volume are primarily at either end of this space with the central region clearly hydrophobic in nature. Nuclear Receptors | Ligand Binding. Ligand Binding Domain 1 is an ADP binding domain that may be ancient and could potentially be used in combination with other ligand binding motifs such as CoA. Keywords: RNA structure; X-ray crystallography; metal ions; nucleotide binding; riboregulation. (E) Ligand binding domain (LBD): Moderately conserved in sequence and highly conserved in structure between the various nuclear receptors.

Crystals of mGluR7 LBD were grown at 293 K by the hanging-drop vapour-diffusion method. 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 … Translations in context of "ligand binding domain" in English-German from Reverso Context: A gene which encodes the ligand binding domain of HNF-4. 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, 2006-02-27 · The domain responsible for hormone binding is the ligand binding domain (LBD). This domain participates in several activities including hormone binding, homo- and/or heterodimerization, formation of the heat-shock protein complex and transcriptional activation and repression.

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.

The protein contains the hinge region and an LBD amino acid sequence identical to that of the human LBD.
