Application of Genetically-Encoded Photoactivatable Crosslinkers to Map Ligand-Binding Sites on G Protein-Coupled Receptors
<p>G protein-coupled receptors (GPCRs) are dynamic membrane proteins that bind extracellular molecules to transduce biological signals. Although GPCRs represent the largest class of targets for therapeutic agents, ligand-binding sites have been precisely defined for only a small percentage of the …

The effect of hyperosmolarity on fluid-phase and receptor-mediated endocytosis in P388D1 macrophages
… components can be internalized by either receptor-mediated or fluid-phase endocytosis. Receptor-mediated endocytosis involves the internalization of receptor-ligand complexes into coated vesicles of about 0.1 μm in diameter. The average diameter of primary pinocytic vesicles has been …

Modeling of interactions between vascular endothelial growth factor family members and their receptors KDR and Flt-1
… are mediated by Flt-1 and KDR, two cell-surface receptors selectively expressed by vascular endothelial cells. A secreted form of Flt-1 (sFlt1) retains high affinity for VEGF and can compete for VEGF binding, thereby inhibiting angiogenic responses. In this study, a computational model of this …

Mechanisms of action for aryl hydrocarbon receptor ligands in the PLHC-1 cell line
Aryl hydrocarbon receptor (AHR) expression and activity was characterized in the teleost hepatoma cell line, PLHC-1. This work was carried out in order to gain insights into mechanisms of halogenated aromatic hydrocarbon (HAH) toxicity. The results improve our ability to characterize the risks …

STUDY OF COVALENT AND NON COVALENT INTERACTIONS OF BIOPOLYMER BY MASS SPECTROMETRY
ESI-MS screening methods directly detect ligand-target non covalent complexes in the gas phase and allow inference of affinity (and specificity) of the ligand-target interaction in solution [1, 2]. The identity of different complexes can be directly assessed as the mass of each molecule works as …

Evidence that ARNT plays a role in the regulation of the immunoglobulin heavy chain enhancer and identification of a putative ARNT ligand
… In our study we tested the function of ARNT (Ah receptor nuclear translocator) at the IgH (immunoglobulin heavy chain) enhancer. We were able to determine that ARNT appears to partially down-regulate activation at the IgH enhancer by Pan-1 in transient transfection assays by cotransfection of the …
