A review with 6 refs. of the authors' work in developing a biophys. technique to investigate the structure, function and dynamics of membrane receptors. A fluorescence-based approach has been developed and applied to the prototypic G protein-coupled recept ...
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 ...
In Drosophila, the immune deficiency (Imd) pathway controls antibacterial peptide gene expression in the fat body in response to Gram-negative bacterial infection. The ultimate target of the Imd pathway is Relish, a transactivator related to mammalian P105 ...
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 ...
We have expressed the 5-HT3 receptor with two transient expression sytems: the Semliki Forest virus and the HEK293EBNA. Both systems allow the rapid expression of functional receptor protein at very high level: up to 107 receptors per cell. Large scale pro ...
Novel fluorescence approaches to investigate ligand recognition and structure of G protein-coupled receptors in native membranes have been developed. These methods combine the biosynthetic incorporation of unnatural fluorescent amino acids at known sites i ...
A review. Cell-based assays are the predominant means of assessing activation of ionotropic receptors and G protein-coupled receptors (GPCRs), but are limited by their inherent complexity. Here we present an approach to immobilize receptors stably and with ...
G protein-coupled receptors (GPCRs) constitute a large class of seven transmembrane proteins, which bind selectively agonists or antagonists with important consequences for cellular signaling and function. Comprehension of the mol. details of ligand bindin ...
Fluorescence Correlation Spectroscopy (FCS) is a suitable technique to investigate biomol. interactions. The advantage of FCS lies in its wide dynamic range in the time and concn. domain, its sensitivity, and thus in the small amt. of material needed. The ...
