S-nitrosylation is required for β2AR desensitization and experimental asthma.

Journal Article Mol Cell · August 18, 2022 The β2-adrenergic receptor (β2AR), a prototypic G-protein-coupled receptor (GPCR), is a powerful driver of bronchorelaxation, but the effectiveness of β-agonist drugs in asthma is limited by desensitization and tachyphylaxis. We find that during activation ... Full text Link to item Cite

Structural studies of phosphorylation-dependent interactions between the V2R receptor and arrestin-2.

Journal Article Nat Commun · April 22, 2021 Arrestins recognize different receptor phosphorylation patterns and convert this information to selective arrestin functions to expand the functional diversity of the G protein-coupled receptor (GPCR) superfamilies. However, the principles governing arrest ... Full text Link to item Cite

DeSiphering receptor core-induced and ligand-dependent conformational changes in arrestin via genetic encoded trimethylsilyl 1H-NMR probe.

Journal Article Nat Commun · September 25, 2020 Characterization of the dynamic conformational changes in membrane protein signaling complexes by nuclear magnetic resonance (NMR) spectroscopy remains challenging. Here we report the site-specific incorporation of 4-trimethylsilyl phenylalanine (TMSiPhe) ... Full text Link to item Cite
