Molecular model for the solubilization of membranes into nanodisks by styrene maleic Acid copolymers.
A recent discovery in membrane research is the ability of styrene-maleic acid (SMA) copolymers to solubilize membranes in the form of nanodisks allowing extraction and purification of membrane proteins from their native environment in a single detergent-free step. This has important implications for membrane research because it allows isolation as well as characterization of proteins and lipids...
متن کاملNanoparticle self-assembly in mixtures of phospholipids with styrene/maleic acid copolymers or fluorinated surfactants.
Self-assembling nanostructures in aqueous mixtures of bilayer-forming lipids and micelle-forming surfactants are relevant to in vitro studies on biological and synthetic membranes and membrane proteins. Considerable efforts are currently underway to replace conventional detergents by milder alternatives such as styrene/maleic acid (SMA) copolymers and fluorinated surfactants. However, these com...
متن کاملSMA-SH: Modified Styrene-Maleic Acid Copolymer for Functionalization of Lipid Nanodiscs.
Challenges in purification and subsequent functionalization of membrane proteins often complicate their biochemical and biophysical characterization. Purification of membrane proteins generally involves replacing the lipids surrounding the protein with detergent molecules, which can affect protein structure and function. Recently, it was shown that styrene-maleic acid copolymers (SMA) can disso...
متن کاملSynthesis of fenoprofen and gemfibrozil styrene-maleic acid copolymer conjugates.
Two types of polymer-drug conjugates were synthesized starting from styrene-maleic acid anhydride copolymer (SMA). Fenoprofen and gemfibrozil were chosen as model drugs because of their short plasma half lives. Both drugs were first converted to their 2-aminoethylamides, which possess free amino groups capable of reacting with SMA anhydride rings. By modifying the degree and type of substitutio...
متن کاملGPCR-styrene maleic acid lipid particles (GPCR-SMALPs): their nature and potential.
G-protein-coupled receptors (GPCRs) form the largest class of membrane proteins and are an important target for therapeutic drugs. These receptors are highly dynamic proteins sampling a range of conformational states in order to fulfil their complex signalling roles. In order to fully understand GPCR signalling mechanisms it is necessary to extract the receptor protein out of the plasma membran...
