A nanodisc is a synthetic model membrane system which assists in the study of membrane proteins.[1] It is composed of a lipid bilayer of phospholipids with the hydrophobic edge screened by two amphipathic proteins. These proteins are called membrane scaffolding proteins (MSP) and align in double belt formation.[2][3][4] Nanodiscs are structurally very similar to high-density lipoproteins (HDL) and the MSPs are modified versions of apolipoprotein A1 (apoA1), the main constituent in HDL. Nanodiscs are useful in the study of membrane proteins because they can solubilise and stabilise membrane proteins[5] and represent a more native environment than liposomes, detergent micelles, bicelles and amphipols.

Peptide nanodiscs[edit]

In peptide nanodiscs, the lipid bilayer is screened by amphipathic peptides instead of two MSPs. Peptide nanodiscs are structurally similar to MSP nanodiscs and the peptides also align in a double belt. They can stabilise membrane proteins,[6] but have higher polydispersity and are structurally less stable than MSP nanodiscs. Recent studies, however, showed that dimerization[7] and polymerization[8] of the peptides make them more stable.
