Default Fluorine-19 NMR of integral membrane proteins illustrated with studies of GPCRs.

Fluorine-19 NMR of integral membrane proteins illustrated with studies of GPCRs.

Fluorine-19 NMR of integral membrane proteins illustrated with studies of GPCRs.

Curr Opin Struct Biol. 2013 Aug 7;

Authors: Didenko T, Liu JJ, Horst R, Stevens RC, Wüthrich K

Abstract
Fluorine-19 is a spin-½ NMR isotope with high sensitivity and large chemical shift dispersion, which makes it attractive for high resolution NMR spectroscopy in solution. For studies of membrane proteins it is further of interest that (19)F is rarely found in biological materials, which enables observation of extrinsic (19)F labels with minimal interference from background signals. Today, after a period with rather limited use of (19)F NMR in structural biology, we witness renewed interest in this technology for studies of complex supramolecular systems. Here we report on recent (19)F NMR studies with the G protein-coupled receptor family of membrane proteins.

NMR structures of polytopic integral membrane proteins.
NMR structures of polytopic integral membrane proteins. NMR structures of polytopic integral membrane proteins. Mol Membr Biol. 2011 Aug 2; Authors: Patching SG Abstract Membrane proteins represent up to 30% of the proteins in all organisms, they are involved in many biological processes and are the molecular targets for around 50% of validated drugs. Despite this, membrane proteins represent less than 1% of all high-resolution protein structures due to various challenges associated with applying the main biophysical techniques used for...

Curr Opin Chem Biol. 2011 Jun 18; Authors: Kang C, Li Q Signals between a cell and its environment are often transmitted through membrane proteins; therefore, many membrane proteins, including G protein-coupled receptors (GPCRs) and ion channels, are important drug targets. Structural information about membrane proteins remains limited owing to challenges in protein expression, purification and the selection of membrane-mimicking systems that will...
