General description

The nanodisc concept is derived from high density lipoprotein (HDL) particles and their primary protein component, apolipoprotein. The nanodisc is a non-covalent structure of phospholipid bilayer and membrane scaffold protein (MSP), a genetically engineered protein, which mimics the function of Apolipoprotein A-1 (ApoA-1). A soluble nanodisc assembles as the phospholipid forms a bilayer, which is encircled by two amphipathic MSP molecules covering the hydrophobic alkyl chains of the bilayer. The length of the MSP controls the size of the nanodisc structure. MSP1E3D1 yields nanodiscs of ~12.9 nm. The thickness of a nanodisc is dependent on the type of phospholipid incorporated (typically 4.6−5.6 nm).

Application

Nanodisc soluble lipid bilayer systems have proven to be a widely applicable means for rendering membrane proteins soluble in aqueous solutions in a native-like bilayer environment where they remain monodisperse and active. The critical component of nanodiscs is the encircling amphipathic helical protein belt (membrane scaffold protein).
The nanodisc system has been employed to incorporate a wide variety of proteins including GPCRs, P450s, bacteriorhodopsin, coagulation factors, cholera toxin, TAR receptor and aromatase.

ChRmine, a recently discovered pump-like cation-conducting channelrhodopsin, exhibits puzzling properties (large photocurrents, red-shifted spectrum, and extreme light sensitivity) that have created new opportunities in optogenetics. ChRmine and its homologs function as ion channels but, by primary sequence, more closely resemble

They have a compact single immunoglobulin domain organization, bind target proteins with high affinities while reducing their conformational heterogeneity and stabilize multi-protein complexes. Here we demonstrate that engineered nanobodies can also
