The peroxisome proliferator-activated receptor-gamma (PPARgamma) is a nuclear receptor that controls the expression of a large array of genes involved in adipocyte differentiation, lipid storage and insulin sensitization. PPARgamma is bound and activated b ...
G protein-coupled receptors (GPCRs) constitute an abundant family of membrane receptors of high pharmacol. interest. Cell-based assays are the predominant means of assessing GPCR activation, but are limited by their inherent complexity. Functional mol. ass ...
The 5-hydroxytryptamine receptor of type 3 was investigated by fluorescence correlation spectroscopy (FCS). Binding constants of fluorescently labeled ligands, the stoichiometry, and the mass of the receptor are readily accessible by this technique, while ...
A highly-sensitive surface fluorescence technique was combined with a powerful method for the oriented reversible immobilization of membrane proteins on oxide surfaces. Affinity and kinetic parameters of the interaction of the receptor and a fluorescent li ...
Tumor necrosis factor TNF can trigger increases in membrane conductance of mammalian cells in a receptor-independent manner via its lectin-like domain. A lectin-deficient TNF mutant, lacking this activity, was able to bind to artificial liposomes in a pH-d ...
A fluorescently labeled ligand for the 5-HT3 serotonin receptor was synthesized and its sub-nanomolar affinity for the purified, detergent solubilized receptor was measured. The change in the ligand's fluorescence upon receptor binding was used to directly ...
Peroxisome proliferator-activated receptors are nuclear receptors with pleiotropic effects on intra- and extracellular lipid metabolism, glucose homeostasis, inflammation control, and cell proliferation. This review addresses the respective roles of the di ...
Ligand binding to the nicotinic acetylcholine receptor is studied by surface plasmon resonance. Biotinylated bungarotoxin, immobilized on a streptavidin-coated gold film, binds nicotinic acetylcholine receptor both in detergent-solubilized and in lipid ves ...
The human and simian immunodeficiency viruses (HIV and SIV) downregulate the cell surface expression of CD4, their primary receptor, and of class I histocompatibility complex (MHC-I), a critical mediator of immune recognition. While the first of these effe ...
