Ligand Binding Domain. Nuclear hormone receptors are ligand-activated transcription factors that regulate gene expression by interacting with specific DNA sequences upstream of their target genes. The mechanism of action for these receptors involves as a first step activation through binding of the hormone and as a second step the receptor binding to DNA.

Alternatively, Sia-binding could directly mediate CD22 interaction to the BCR or the ligand-binding domain could have no influence on signaling at all. We have addressed the role of the ligand-binding domain of CD22 by development of a new class of Sia analogs as artificial high affinity Siglec ligands.

The ligand binding domain is the open volume bounded by H3, H 5 and the Loop. 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 Studies on N terminus-truncated hMRs showed that the ligand-binding domain (LBD: amino acids 734-984) has a lower affinity for aldosterone than the entire receptor [dissociation constant (Kd) 2.9 vs. 0.47 nM] and does not interact with hsp90. 1998-11-20 · apo-PPARgamma ligand binding domain (LBD) determined to 2.9-A resolution. Although the structure of apo-PPARgamma-LBD retains the overall fold described previously for other nuclear receptor LBDs, three distinct structural differences are evident.

(E) Ligand binding domain (LBD): Moderately conserved in sequence and highly conserved in structure between the various nuclear receptors. The structure of the LBD is referred to as an alpha helical sandwich fold in which three anti parallel alpha helices (the "sandwich filling") are flanked by two alpha helices on one side and three on the other (the "bread"). Studies on N terminus-truncated hMRs showed that the ligand-binding domain (LBD: amino acids 734-984) has a lower affinity for aldosterone than the entire receptor [dissociation constant (Kd) 2.9 vs. 0.47 nM] and does not interact with hsp90. This Estrogen Receptor (ER) Alpha Ligand Binding Domain (LBD) is a 62.80 kDa recombinant human protein (amino acids 282-595) expressed as a GST fusion protein in baculovirus-infected insect cells. It was expressed and purified in the absence of exogenous ligands.

E) – Ligand binding domain (LBD) containing activation function 2 (AF-2), responsible for agonist induced activity (activity in the presence of bound agonist) AF-2 binds either the N-terminal FXXFL motif intramolecularly or coactivator proteins (containing the LXXLL or preferably FXXFL motifs) A ligand dependent nuclear export signal The class C GPCRs are distinguished by their large N-terminal tail, which also contains a ligand-binding domain. Upon glutamate-binding to an mGluR, the N-terminal tail undergoes a conformational change that leads to its interaction with the residues of the extracellular loops and TM domains.
