Abstract:

Membrane proteins are responsible for a wide range of essential physiological processes, and important drug targets for treating diseases. However, structural study on membrane proteins lags far behind that on soluble proteins, and this, in large part, is due to technical difficulties in preparing homogeneous, stable and structurally relevant samples in a membrane-like environment. Phospholipid bilayer Nanodisc is novel model membrane derived from highdensity lipoprotein particles, and has proven to be useful in structural studies on membrane proteins. It has been shown that Nanodisc can provide a “native-like” lipid bilayer environment for many membrane proteins, such as VDAC-1 (voltage-dependent anion channel), GPCRs (G-protein-coupled receptors) and cytochrome P450s, thus enabling structural studies on these membrane proteins with NMR/surface plasmon resonance (SPR) techniques. Furthermore, with more sophisticated techniques such as modification of membrane scaffold proteins (MSP), the use of Nanodisc may yield structural and functional insights into a wide variety of membrane proteins in a biologically relevant membrane environment.
