Default Localized Chemical Remodeling for Live Cell Imaging of Protein-Specific Glycoform

Localized Chemical Remodeling for Live Cell Imaging of Protein-Specific Glycoform


Live cell imaging of protein-specific glycoforms is important for the elucidation of glycosylation mechanisms and identification of disease states. The currently used metabolic oligosaccharide engineering (MOE) technology permits routinely global chemical remodeling (GCM) for carbohydrate site of interest, but can exert unnecessary whole-cell scale perturbation and generate unpredictable metabolic efficiency issue. A localized chemical remodeling (LCM) strategy for efficient and reliable access to protein-specific glycoform information is reported. The proof-of-concept protocol developed for MUC1-specific terminal galactose/N-acetylgalactosamine (Gal/GalNAc) combines affinity binding, off-on switchable catalytic activity, and proximity catalysis to create a reactive handle for bioorthogonal labeling and imaging. Noteworthy assay features associated with LCM as compared with MOE include minimum target cell perturbation, short reaction timeframe, effectiveness as a molecular ruler, and quantitative analysis capability.A localized chemical remodeling strategy for live cell imaging of protein-specific glycoform is reported. Compared with the currently used global chemical remodeling method, namely metabolic oligosaccharide engineering, desired assay features of this approach include minimum target cell perturbation, short reaction timeframe, effectiveness as a molecular ruler, and quantitative analysis capability.

[NMR paper] A general mechanism of photoconversion of green-to-red fluorescent proteins based on blue and infrared light reduces phototoxicity in live-cell single-molecule imaging
A general mechanism of photoconversion of green-to-red fluorescent proteins based on blue and infrared light reduces phototoxicity in live-cell single-molecule imaging Photoconversion of fluorescent proteins by blue and complementary near-infrared light, termed primed conversion (PC), is a mechanism recently discovered for Dendra2. We demonstrate that controlling the conformation of arginine at residue 66 by threonine at residue 69 of fluorescent proteins from Anthozoan families (Dendra2, mMaple, Eos, mKikGR, pcDronpa protein families) represents a general route to facilitate PC....

Live Cell NMR. Related Articles Live Cell NMR. Annu Rev Biophys. 2014 May 6;43:171-192 Authors: Freedberg DI, Selenko P Abstract Ever since scientists realized that cells are the basic building blocks of all life, they have been developing tools to look inside them to reveal the architectures and mechanisms that define their biological functions. Whereas "looking into cells" is typically said in reference to optical microscopy, high-resolution in-cell and on-cell nuclear magnetic resonance (NMR) spectroscopy is a powerful method...
