چکیده
Dr. Wensel received his Ph.D. in chemistry from the University of California, Davis. He then moved on to Stanford University as a post-doctoral fellow where he studied with Lubert Stryer. Currently, Dr. Wensel is professor of biochemistry & molecular biology at the Baylor College of Medicine, where his research focuses on signal transduction of G-protein coupled receptors in the retina and brain. Recent work in his laboratory has yielded considerable insight into the role that Regulator of G-Protein Signaling (RGS) proteins play in visual signal transduction. Using a vast array of techniques including X-ray crystallography, membrane biochemistry, and whole animal genetic manipulation, he aims to characterize the molecular mechanisms that are crucial for the proper regulation of GPCR signaling in the central nervous system.

Identification of small-molecule inhibitors of RGS4 using a high-throughput flow cytometry protein interaction assay.
Regulators of G-protein signaling (RGS) proteins are important components of signal transduction pathways initiated through G-protein-coupled receptors (GPCRs). RGS proteins accelerate the intrinsic GTPase activity of G-protein alpha-subunits (Galpha) and thus shorten the time course and reduce the magnitude of G-protein alpha- and betagamma-subunit signaling. Inhibiting RGS action has been pro...
متن کاملReversible, allosteric small-molecule inhibitors of regulator of G protein signaling proteins.
Regulators of G protein signaling (RGS) proteins are potent negative modulators of G protein signaling and have been proposed as potential targets for small-molecule inhibitor development. We report a high-throughput time-resolved fluorescence resonance energy transfer screen to identify inhibitors of RGS4 and describe the first reversible small-molecule inhibitors of an RGS protein. Two closel...
متن کاملA FRET-Based High Throughput Screening Assay to Identify Inhibitors of Anthrax Protective Antigen Binding to Capillary Morphogenesis Gene 2 Protein
Anti-angiogenic therapies are effective for the treatment of cancer, a variety of ocular diseases, and have potential benefits in cardiovascular disease, arthritis, and psoriasis. We have previously shown that anthrax protective antigen (PA), a non-pathogenic component of anthrax toxin, is an inhibitor of angiogenesis, apparently as a result of interaction with the cell surface receptors capill...
متن کاملScreening for Novel LRRK2 Inhibitors Using a High-Throughput TR-FRET Cellular Assay for LRRK2 Ser935 Phosphorylation
BACKGROUND Mutations in the leucine-rich repeat kinase-2 (LRRK2) have been linked to Parkinson's disease. Recent studies show that inhibition of LRRK2 kinase activity decreased the level of phosphorylation at its own Ser910 and Ser935, indicating that these sites are prime targets for cellular readouts of LRRK2 inhibition. METHODOLOGY/PRINCIPAL FINDINGS Using Time-Resolved Förster Resonance E...
متن کاملKinetic characterization of trans-proteolytic activity of Chikungunya virus capsid protease and development of a FRET-based HTS assay
Chikungunya virus (CHIKV) capsid protein (CVCP) is a serine protease that possesses cis-proteolytic activity essential for the structural polyprotein processing and plays a key role in the virus life cycle. CHIKV being an emerging arthropod-borne pathogenic virus, is a public health concern worldwide. No vaccines or specific antiviral treatment is currently available for chikungunya disease. Th...
